<div class="post-body" itemprop="articleBody">
|
||
<p>通常情况下我们在HTML中引用js没有在文件名后面附加任何参数，即：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title=""><script type="text/javascript" src="test.js"></script>
|
||
|
||
</pre>
|
||
|
||
<p>其实我们在其后面加上一些附加参数，我们现在使用的浏览器也是可以识别，同样找到我们需要的js的。（IE6没有测试，不清楚是否支持），即如下：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title=""><script type="text/javascript" src="test.js?div=mydiv&name=tome&age=3"></script>
|
||
|
||
</pre>
|
||
|
||
<p>我们现在需要做的就是如何取出这其中的参数。如：div=mydiv;name=tom;age=3。首先附上我自己写的一个js方法，就是使用了常用的函数，如indexOf,substring,split等方法：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">//你需要获取值的js文件名
|
||
var fileName = "test.js";
|
||
//获取到所有<script>对象
|
||
var scripts = document.getElementsByTagName("script");
|
||
for(var i =0; i< scripts.length;i++){
|
||
var src = scripts[i].src;
|
||
//取得你想要的js文件名
|
||
if(src.indexOf(fileName)!==-1){
|
||
//获取js文件名后面的所有参数
|
||
src = src.substring(src.lastIndexOf(fileName+"?")+(fileName.length+1));
|
||
var array = src.split("&");
|
||
//将参数一个一个遍历出来
|
||
for(var j=0;j<array.length;j++){
|
||
var finalObj = array[j].split("=");
|
||
console.log("参数："+finalObj[0]+"值："+finalObj[1]);
|
||
}
|
||
}
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>我在网上又看到另外一个前辈主要使用了RegExp和match函数，以正则表达式的方式完成了同样的操作，代码如下：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">var jsFileName = "testParam.js";
|
||
var rName = new RegExp(jsFileName+"(\\?(.*))?$")
|
||
var jss=document.getElementsByTagName('script');
|
||
for (var i = 0;i < jss.length; i++){
|
||
var j = jss[i];
|
||
if (j.src&&j.src.match(rName)){
|
||
var oo = j.src.match(rName)[2];
|
||
if (oo&&(t = oo.match(/([^&=]+)=([^=&]+)/g))){
|
||
for (var l = 0; l < t.length; l++){
|
||
r = t[l];
|
||
var tt = r.match(/([^&=]+)=([^=&]+)/);
|
||
if (tt)
|
||
document.write('参数：' + tt[1] + '，参数值：' + tt[2] + '<br />');
|
||
}
|
||
}
|
||
}
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>在测试确定这两个函数都真实可用的情况下，我突然冒出另外一个想法，想测试一下这两种方法到底效率怎么样，比较他们执行的时间的长短：</p>
|
||
<p>测试条件：</p>
|
||
<ul>
|
||
<li>将两个方法的输出都换成一致console.log();</li>
|
||
<li>分别在代码执行前和执行后获取当前时间，相减获取这种方法的执行时间。</li>
|
||
<li>所有测试都在同一台笔记本电脑下，我将测试chrome 21,firefox 14,IE9。每个浏览器分别执行5次</li>
|
||
</ul>
|
||
<p>我用的测试方法代码：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">var original = new Date().getTime(); //在执行方法前
|
||
|
||
//在执行方法后
|
||
|
||
console.log(new Date().getTime()-original);
|
||
|
||
</pre>
|
||
|
||
<p>测试5次的结果为：</p>
|
||
<p><a href="/images/2012/08/saa.png"><img class="aligncenter size-full wp-image-2182" title="执行结果统计" src="/images/2012/08/saa.png" alt="" width="360" height="132" /></a></p>
|
||
<p>结果有点出乎我的意料：在chrome和firefox中普通方式的时间都要好于使用正则表达式这种方式，而更神奇的是在IE中这两种时间都是0毫秒，只有在我快速刷新的时候才偶尔出现时间，一般只有1或者2ms。</p>
|
||
<p>确实很难理解为什么IE时间为0毫秒，只有希望高人可以解答一下了。</p>
|
||
<p>不过不管怎样，至少解决了获取参数这个问题。也不错！</p>
|
||
<p><strong>更新</strong>：根据 <a target="_blank" rel="noopener" href="http://weibo.com/jeffz">@老赵</a>的建议我将测试次数变到反复执行该方法1000次再比较结果，出现如下的数据：（注意较上图正则和普通的位置对调了一下）</p>
|
||
<p><a href="/images/2012/08/1111111111.png"><img class="aligncenter size-full wp-image-2191" title="执行1000次的结果" src="/images/2012/08/1111111111.png" alt="" width="362" height="169" /></a></p>
|
||
<p>欢迎大家讨论。</p>
|
||

<p>跨域问题在我们开发web应用的时候经常遇到，但一直没有很好的解决方案。目前可能大家认为相对比较好使的就是——JSONP技术。不过这样前台通常需要告诉后台需要返回的函数名称，而后台需要向前台前台返回的则是一个可以执行的代码段。这样在后台处理的时候就相对麻烦一些。</p>
|
||
<p>其实在新的W3C标准中，我们只需要在服务器后端添加一句话即可以比较好的解决跨域问题。如java servlet中：</p>
|
||
<pre class="brush: java; title: ; notranslate" title="">response.setHeader("Access-Control-Allow-Origin","http://toozhao.com");
|
||
|
||
</pre>
|
||
|
||
<p>这段代码的意思就是，允许来自toozhao.com的跨域HTTP请求，当然我们也可以使用通配符 “*”,这样任意的请求都可以访问这个地址了，而不会出现跨域的问题。</p>
|
||
<p>不过据其他文档中介绍，这样做是不安全的。因为这样服务器不能访问document.cookie 对象。不知道请求者的相关信息，而微软的介绍文档中说到：</p>
|
||
<blockquote>
|
||
<p><strong>安全警报</strong> 为了保护用户数据，跨域请求是匿名的，这意味着服务器无法轻松找出正在请求数据的用户。 因此，只应请求和响应不属于敏感信息或个人身份识别信息的跨域数据。</p>
|
||
</blockquote>
|
||
<p>因此为了安全，我们只应该向我们能保证其安全的站点提供Access-Control-Allow-Origin，即（CORS）。或者对可以公开的数据采用该种方式。</p>
|
||
<p>我个人认为在下面的情景中，比较适合采用这种跨域处理技术：</p>
|
||
<p><a href="/images/2012/08/aa1.png"><img class="aligncenter size-full wp-image-2179" title="aa" src="/images/2012/08/aa1.png" alt="" width="622" height="432" /></a></p>
|
||
<p>此外，CORS还有一些其他属性可以设置：</p>
|
||
<pre class="brush: xml; title: ; notranslate" title="">Access-Control-Allow-Origin: http://www.toozhao.com //设置允许跨域的地址
|
||
Access-Control-Allow-Methods: POST, GET //设置跨域允许的方法
|
||
Access-Control-Allow-Headers: NCZ //设置跨域允许的头部信息
|
||
Access-Control-Max-Age: 1728000 //设置跨域允许的最大时间
|
||
|
||
</pre>
|
||
|
||
<p>好了有了上面的这些参数，只要我们在java 中可以获取到HttpServletResponse 对象，即可以设置属性。被允许的前台就可以使用一般的ajax调用了。如jquery：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">$.ajax({
|
||
|
||
url: 'http://toozhao.com/test/xxx',
|
||
|
||
method: 'GET'，
|
||
|
||
success: function(msg){
|
||
|
||
console.log(msg);
|
||
|
||
}
|
||
|
||
});
|
||
|
||
</pre>

|
||
<p>我们在开发java web 的程序时候，经常会需要给用户提示信息，或者页面。最常见的，比如用户输入了一个不存在的网址，默认情况下Tomcat会给用户返回一个默认的页面。如下所示：</p>
|
||
<p><a href="/images/2012/08/22.jpg"><img class="aligncenter size-full wp-image-2165" title="22" src="/images/2012/08/22.jpg" alt="" width="529" height="182" /></a></p>
|
||
<p>这个页面千篇一律。我们完全可以给用户展示一个自定义的页面。</p>
|
||
<p>其实java web程序中web.xml 本身就支持自定义错误页面，我们只需要在web.xml添加如下信息：</p>
|
||
<pre class="brush: xml; title: ; notranslate" title=""><error-page>
|
||
<error-code>404</error-code>
|
||
<location>/errorpage/404.html</location>
|
||
</error-page>
|
||
<error-page>
|
||
<error-code>401</error-code>
|
||
<location>/errorpage/401.html</location>
|
||
</error-page>
|
||
<error-page>
|
||
<error-code>500</error-code>
|
||
<location>/errorpage/500.html</location>
|
||
</error-page>
|
||
|
||
</pre>
|
||
|
||
<p>当然“error-code”，可以自己选择在程序中出现得最多的错误码。我个人认为通常我们拦截：</p>
|
||
<p>401：未授权</p>
|
||
<p>404：没有找到页面</p>
|
||
<p>500：服务器内部错误</p>
|
||
<p>这三个即可。在“location”中配置你自己的html,当然页面样式，内容这些这些都可以自己定义。这个就看你自己啦。</p>
|
||
<p>如果我们不做其他操作，当系统出现这些错误情况时，服务器就会自动调用我们配置的网页。当然我们可以自行在恰当的时候使用它。</p>
|
||
<p>在servlet或者其他可能访问到HttpServletResponse对象的地方，使用：</p>
|
||
<pre class="brush: java; title: ; notranslate" title="">response.sendError(404); //404为你需要的错误代码
|
||
|
||
//也可以向前台网页传输错误语句，不过前台网页需要相应支持。这里没有实现
|
||
|
||
response.sendError(404,"这里写想要输出到前台的提示信息");
|
||
|
||
</pre>
|
||
|
||
<p>在java中还可以使用：</p>
|
||
<pre class="brush: java; title: ; notranslate" title="">response.setStatus(404); //设置状态码
|
||
|
||
</pre>
|
||
|
||
<p>设置状态码来实现，不过这并不能调用配置的自定义页面。只是在前台显示错误，并无输出。</p>

<div class="post-body" itemprop="articleBody">
|
||
<p>在java web中我们一般都是使用commons-fileupload 和cos 进行服务器端上传文件的处理，而这种情况通常是我们通过在网页中的form标签中设置enctype=”multipart/form-data”这样的信息，才可以。否则commons-fileupload和cos都不能获取到文件。HTML网页设置格式如下图所示：</p>
|
||
<pre class="brush: xml; title: ; notranslate" title=""><html>
|
||
<body>
|
||
<h2>Hello upload-file</h2>
|
||
<form method="POST" action="upload" enctype="multipart/form-data">
|
||
file upload:<br>
|
||
<input type="file" name="file" />
|
||
<input type="submit" value="submit">
|
||
</form>
|
||
</body>
|
||
</html>
|
||
|
||
</pre>
|
||
|
||
<p>这只是一个简单例子，但如果我们遇到这样的情况：我们有一个java本地的客户端，使用HTTP协议来上传文件，不过这里没有表单。commons-fileupload的服务器端就会报错</p>
|
||
<p>其实解决的办法也很简单，面对没有设置”multipart/form-data”属性的客户端，我们可以通过request.getInputStream() 获取输入流，从中读取文件内容。</p>
|
||
<p>下面是我写的一断简单代码，把输入流信息，写入到C盘的一个文件：</p>
|
||
<pre class="brush: java; title: ; notranslate" title="">protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
|
||
|
||
InputStream input= request.getInputStream(); //获取流
|
||
OutputStream out = new FileOutputStream(new File("c://test.txt"));
|
||
byte[] buffer = new byte[1024];
|
||
int count;
|
||
while ((count = input.read(buffer)) != -1) {
|
||
out.write(buffer, 0, count); //写文件
|
||
}
|
||
out.flush();
|
||
out.close();
|
||
input.close();
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>不过这种方式是不能直接解析上面那种form表单的文件上传方式，他会在文件的前后各加上一段信息,下面是一个form表单上传，输入流中的信息：</p>
|
||
<pre class="brush: xml; title: ; notranslate" title="">------WebKitFormBoundaryOPczhvGNCBlneBER
|
||
Content-Disposition: form-data; name="file"; filename="??????.txt"
|
||
Content-Type: text/plain
|
||
#下面是我写入的文件内容
|
||
df03c9cf37c5fbc5a7894e04297127d7
|
||
3a9bb0371ea5789666ab438b3b7e05c2
|
||
#到此为止
|
||
------WebKitFormBoundaryOPczhvGNCBlneBER--
|
||
|
||
</pre>
|
||
|
||
<p>如果form中没有加上enctype=”multipart/form-data”属性信息，输入流中得到的只有在<input value=””>中设置的value值，因此，通过流来获取上传的文件，应该只适合于从客户端直接向服务器写文件。</p>

<p>我们都知道maven是项目构建的神器，不过用maven从国外下载东西的时候这速度可真就不怎么神器了。而且如果你在公司里面使用maven,而公司里面没有自己建一个maven代理仓库的话，大家一起使用maven下载组件的时候，就费力了。</p>
|
||
<p>因此一个公司是完全有必须要搭建一个maven代理仓库的。既可以节省宽带资源、也可以节省其他人编译相同代码说下载组件的时间，而且代理仓库服务器上的组件还可以随时复制、迁移到其他服务器，造福其他程序员。通常情况下，我们使用nexus搭建自己的maven仓库和做公网上那些用得很多的仓库的代理仓库，今天就在这里分享一些我搜集的公网上常用的代理仓库。这些已经能够保证我工作中的maven项目95%以上正常编译了。</p>

<p>这是nexus自己的仓库，本身就包含了很过仓库仓库的代理，不过速度貌似不够快。</p>

<p>spring 这个开源组织提供的仓库的确很多，而在我平时的编译中也经常用到，有一点spring 做得特别牛，那就是它吧很多一般的jar包转成了或者重新制作成了bundle。(bundle是osgi技术中需要的jar包，bundle可以当成普通jar包使用，而普通jar包不能当成bundle使用，举个简单的例子，如果你想把jar包放到你的osgi 应用服务器virgo 或者 jboss as 7中使用，你就必须得用bundle才可以。)所以当你找不到某个包的bundle版本的时候，试试去spring的maven仓库，他的所有包都是bundle.</p>

|

<p>wso2是一个企业级web services中间件，提供了很多，比较强大的组件。如AS， IS,ESB等。大家有兴趣可以看看。</p>
|
||
<p>把这样仓库全部做成你的nexus的代理，就相当于你拥有它们所有仓库的能力了。是不是瞬间战斗力提升了很多。</p>
|
||
<p>如果你想尽快使用你添加的这些代理仓库，请在nexus中更新这些仓库的 index(索引)，你就可以马上使用这些仓库了。</p>

<p>这篇文章，主要是作为一个记录，记录我一个小时之前搞定这个东西的兴奋心情。spring mongodb主要是mongodb-java-driver 进行了一些封装，然后可以配合强大的spring使用。我觉得可以简单把它看成一个mongo的”ORM”框架。通过我从星期五到星期天的捣腾，我发现熟悉spring 框架本身其实是最重要的。好下面直接上吧：</p>
|
||
<p>首先我在eclipse里面建了一个maven项目，你需要添加如下依赖信息(这里用到的spring框架是3.0.6.RELEASE版本)：</p>
|

<pre class="brush: xml; title: ; notranslate" title=""><properties>

</pre>
|
||
|
||
<p>由于这里面的某些依赖可能maven中央仓库没有，所以请在pom里添加下面两个spring的仓库:</p>
|
||
<pre class="brush: xml; title: ; notranslate" title=""><repository>
|
||
<id>spring-maven-release</id>
|
||
<name>Spring Maven Release Repository</name>

<id>spring-maven-milestone</id>

<name>Spring Maven Milestone Repository</name>
|
||
<url>http://maven.springframework.org/milestone</url>
|
||
</repository>
|
||
|
||
</pre>
|
||
|
||
<p>下面进行我们的代码编写,首先我们需要一个简单的java POJO类:person.java用于存储人的信息，其有三个属性：id(和mongodb中的ObjectId对应)，name-姓名，age-年龄。</p>
|
||
<pre class="brush: java; title: ; notranslate" title="">package com.toozhao.mongo.bean;
|
||
|
||
import org.springframework.data.annotation.Id;
|

import org.springframework.data.mongodb.core.mapping.Document;
|

|

/**

|

@Document
|
||
public class Person {
|
||
|
||
@Id
|
||
private String id;
|
||
private String name;
|
||
private int age;
|
||
|
||
public Person() {
|
||
|
||
}
|
||
|
||
public Person(String name, int age) {
|
||
this.name = name;
|
||
this.age = age;
|
||
}
|
||
|
||
public String getId() {
|
||
return id;
|
||
}
|
||
|
||
public String getName() {
|
||
return name;
|
||
}
|
||
|
||
public void setId(String id) {
|
||
this.id = id;
|
||
}
|

|

public void setName(String name) {
|

this.name = name;
|

}
|

public void setAge(int age) {

this.age = age;
|

}
|

public int getAge() {

return age;
|

}
|

@Override
|

public String toString() {
|

return "Person [id=" + id + ", name=" + name + ", age=" + age + "]";
|
||
}
|
||
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>然后我们定义一个执行操作的接口，和其实现类，这里可以看做是一个dao模式。在接口中我们只定义了保存对象和查询一条记录两个方法。</p>
|
||
<pre class="brush: java; title: ; notranslate" title="">package com.toozhao.mongo.repository;
|
||
|
||
import com.toozhao.mongo.bean.Person;
|
||
/**
|
||

|
||
* @author Junv
|
||
*
|
||
*/
|
||
public interface MongoAction {
|
||
|
||
public void saveObject(Person objToSave);
|
||
|
||
public Person findObject(String id);
|
||
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>实现类：</p>
|
||
<pre class="brush: java; highlight: [11,14]; title: ; notranslate" title="">package com.toozhao.mongo.repository;
|
||
|
||
import org.springframework.beans.factory.annotation.Autowired;
|
||
import org.springframework.data.mongodb.core.MongoOperations;
|
||
import org.springframework.data.mongodb.core.query.Criteria;
|
||
import org.springframework.data.mongodb.core.query.Query;
|
||
import org.springframework.stereotype.Repository;
|
||
|
||
import com.toozhao.mongo.bean.Person;
|
||
|
||
@Repository
|
||
public class PersonActionImp implements MongoAction {
|
||
|
||
@Autowired
|
||
MongoOperations operation;
|
||
|
||
public void saveObject(Person objToSave) {
|
||
operation.insert(objToSave);
|
||
|
||
}
|
||
|
||
public Person findObject(String id) {
|
||
return operation.findOne(new Query(Criteria.where("_id").is(id)),
|
||
Person.class);
|
||
|
||
}
|
||
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>@repository,和@autowired是spring框架中的，主要功能是起到类似反射的作用吧，具体我还没弄得很清楚。</p>
|
||
<p>写一个有main方法的java类，对功能进行简单测试：</p>
|
||
<pre class="brush: java; highlight: [20,21,23]; title: ; notranslate" title="">package com.toozhao.mongo;
|
||
|
||
import org.apache.commons.logging.Log;
|
||
import org.apache.commons.logging.LogFactory;
|
||
import org.springframework.context.ConfigurableApplicationContext;
|
||
import org.springframework.context.support.ClassPathXmlApplicationContext;
|
||
|
||
import com.toozhao.mongo.bean.Person;
|
||
import com.toozhao.mongo.repository.MongoAction;
|
||
|
||
public class MainTest {
|
||
|
||
private static final Log log = LogFactory.getLog(MainTest.class);
|
||
|
||
public static void main(String[] args) {
|
||
|
||
log.info("initial -----------------");
|
||
ConfigurableApplicationContext context = null;
|
||
//实例化appliaction Context对象
|
||
context = new ClassPathXmlApplicationContext(
|
||
"META-INF/spring/applicationContext.xml");
|
||
//获取一个MongoAction Bean，以便后面执行相关操作
|
||
MongoAction action = context.getBean(MongoAction.class);
|
||
Person person = new Person("Tom", 11);
|
||
|
||
action.saveObject(person);
|
||
log.info("结果为：" + action.findObject(person.getId()));
|
||
|
||
}
|
||
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>最后，贴出applicationContext文档，里面主要对mongodb进行了简单的配置，和设置了repository的扫描目录（和@repository对应）。</p>

|

<p>当然你还需要做的就是运行这个项目，我们需要在pom.xml里面添加如下代码,<mainClass>为你需要运行的类：</p>
|
||
<pre class="brush: xml; highlight: [7]; title: ; notranslate" title=""><plugin>
|
||
<groupId>org.codehaus.mojo</groupId>
|

<artifactId>exec-maven-plugin</artifactId>

<!-- 你需要执行的类， -->
|

<configuration>
|

<mainClass>com.toozhao.mongo.MainTest</mainClass>
|
||
</configuration>
|
||
</plugin>
|
||
|
||
</pre>
|
||
|
||
<p>最后，使用 mvn exec:java 就可以运行代码了，当然你在有main方法那个类，右键以java程序的方式也可以运行。结果就是你应该可以看到程序像数据库junv.person中插入了一条数据。</p>

<p>这个月，领导说我对程序仓库方面比较了解，所以让我当这方面的一个项目组长，负责nexus仓库的使用和改造等。</p>
|
||
<p>我们小组有4个人，我和另外一个是实习生，还有另外两位是实训生。就是这样一个小组，我们担负的任务是改造nexus。</p>
|
||
<p>但是到现在我感觉到的只有累。</p>
|
||
<p>每天感觉就像生活在使用maven编译项目的过程中。</p>
|
||
<p>所有需求不明确，只是领导和我们小组一起讨论过一次。也没有讨论出什么东西。下来，我按照讨论结果大概写了一个想法和预期的总结。发给了领导。但是就再也没有回应了。</p>
|
||
<p>我那个东西写得很简略，我也不知道哪些东西可以要，哪些应该深入。我也拿不定主义，可就是这样，我被要求写需求，画流程图，画用例图，我觉得很不知所措，我都不知道哪些东西应该做，哪些不应该做，这叫我怎么实现出来。</p>
|
||
<p>我不明白。我也不知道需求怎么写。恼火。</p>
|
||
<p>在编译和大概看nexus的源码的过程中，我们小组都发现，要成功编译它，还真不是一件容易的事。在看他代码吧。几十个MAVEN项目，几乎没什么说明，代理里面注释也不标准，也看不懂代码是怎么样一个结构。我只是想说这个项目太大了，真的太大了。大到我们不能承受地步，而且，我在网上搜，搜不出一条关于它的源码的解析。</p>
|
||
<p>nexus 也很无赖，很多东西很乱，有些前端文字，在专门的js里面，有些又随意分布。更可恶的是，它还有实时从后台下载文字等信息，显示出来。感觉这个公司真的很流氓。</p>
|
||
<p>我不想当组长了，我只是想安心搞我的技术。我技术都不够成熟。我才大四不到啊。我还想继续搞 我的技术。请让我把技术能力提升了以后再说其他的吧。我好累。好累。</p>
|
||
<p>这个组长不好当，更何况要我做的不是用一个项目，而是改人家一个没什么注释的代码。我伤不起。</p>
|
||
<p>who can help me?</p>

<p>full screen (全屏)API,现在已经成为了HTML5的一个官方API，不过目前只是被chrome、firefox、safari浏览器实现了，且他们目前都是用的自行实现的函数，而非W3C官方标准的函数。建议在调用之前都检测一下！</p>
|
||
<p>full screen API主要有两个方法：一是执行全屏，另外一个则是退出全屏。他们的调用方法为：</p>
|
||
<p><strong>执行全屏</strong></p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">var element = XXX //这里你需要得到你的一个网页中的对象，可以是整个网页，或者其中一个节点
|
||
|
||
element.requestFullscreen(); //W3C的方法
|
||
|
||
element.mozRequestFullScreen(); //firefox实现的方法
|
||
|
||
element.webkitRequestFullScreen(); //chrome 和safari实现的方法
|
||
|
||
</pre>
|
||
|
||
<p><strong>退出全屏</strong></p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">element.exitFullScreen(); //W3C
|
||
|
||
element.mozCancelFullScreen(); //firefox
|
||
|
||
element.webkitCancelFullScreen(); //chrome和safari
|
||
|
||
</pre>
|
||
|
||
<p>例如,我想全屏整个页面,那个就应该使用:</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">var documentEle = document.documentElement;
|
||
|
||
documentEle.webkitRequestFullScreen(); //chrome
|
||
|
||
</pre>
|
||
|
||
<p>此外我们还可以监听，full screen 事件，在其状态改变时执行相关操作。</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">document.addEventListener("fullscreenchange", function () {}, false); //w3c
|
||
|
||
document.addEventListener("mozfullscreenchange",function(){},false); //firefox
|
||
|
||
document.addEventListener("webkitfullscreenchange", function () {}, false); //chrome 和safari
|
||
|
||
</pre>
|
||
|
||
<p>如果我们想获取当前某个对象数否处于全屏状态，就可以使用下面这个属性：</p>
|
||
<pre class="brush: jscript; title: ; notranslate" title="">document.fullScreen //w3c
|
||
|
||
document.mozFullScreen //firefox
|
||
|
||
document.webkitIsFullScreen // chrome 和safari
|
||
|
||
</pre>
|
||
|
||
<p>经过我的测试（chrome 22），应该是HTML 里面所有对象都是可以被全屏的,如：<iframe>,<img>,<p>,网页本身。不过我们是不能一开始网页就让其处于全屏状态。而需要一些行为来触发这个事件。</p>
|
||
<p>在css 里面也有一个对应的选择器来修饰full screen：</p>
|
||
<pre class="brush: css; title: ; notranslate" title="">html:fullscreen{
|
||
|
||
font-size:30px;
|
||
color:white;
|
||
background:blue;
|
||
|
||
}
|
||
|
||
html:-moz-full-screen{
|
||
font-size:30px;
|
||
color:white;
|
||
background:blue;
|
||
}
|
||
html:-webkit-full-screen{
|
||
font-size:30px;
|
||
color:white;
|
||
background:blue;
|
||
}
|
||
|
||
</pre>
|
||
|
||
<p>目前IE9 也是不支持full screen 全屏 API的，不知道在IE 10里面支持不！微软在这方面做得真的不怎么样啊。</p>
|
||
<blockquote>
|
||
<p><a href="http://toozhao.com/playground/fullscreen.html" title="full screen demo">点我查看我做的demo吧！</a>包含全屏网页，和全屏图片，不过由于图片原因效果不好。但是功能有了。哈哈！</p>

|
||
<p>Mongodb是一个非关系型数据库软件(NoSql),以类似json的形式bson存储数据,bson有二进制的json的意思,官方说bson的效率更高,很适合存储类似于对象的数据,这里权当把自己学习的过程记录下来.</p>
|
||
<p>首先是下载安装mongodb,请到<a target="_blank" rel="noopener" href="http://www.mongodb.org/downloads">这里</a>下载适合你操作系统的相应版本,这里我们以windows作为介绍.</p>
|
||
<p>将下载的压缩包解压到一个文件夹,我这里为 f:\mongodb</p>
|
||
<p>在mongodb文件夹下创建一个data文件夹,用于存储你的数据库文件.</p>
|
||
<p>下面就可以开始安装运行mongodb了,mongodb不需要进行安装,直接运行即可,进入命令行:</p>
|
||
<blockquote>
|
||
<p>cd f:\mongodb\bin</p>
|
||
<p>mongod.exe –dbpath=f:\mongodb\data</p>
|
||
</blockquote>
|
||
<p>–dbpath 为配置你的数据库文件路径,注意在等号附近不要空格哦,否则不能正常运行</p>
|
||
<p><a href="/images/2012/07/1_conew1.jpg"><img class="aligncenter size-full wp-image-2120" title="1_conew1" src="/images/2012/07/1_conew1.jpg" alt="" width="500" height="185" /></a></p>
|
||
<p>这样mongodb的服务器端就已经成功运行起来了.下面运行客户端即可.mongodb默认是没有设置登录的用户名和密码,所以我们打开客户端,就可以直接连接上服务器.</p>
|
||
<blockquote>
|
||
<p>f:\mongodb\bin\mongo.exe</p>
|
||
</blockquote>
|
||
<p>如果连接成功, 你会看到会默认连上test数据库.(connectting to :test)</p>
|
||
<p>下面我们就可以进行一些简单的操作了.</p>
|
||
<blockquote>
|
||
<p>help // 查看帮助信息</p>
|
||
<p>db.help() //在当前数据库内的帮助信息</p>
|
||
<p>show dbs //查看所有的数据库列表</p>
|
||
<p>use dbname //dbname为你的数据库,如果你想创建一个新的数据库,将dbname写成一个不存在的数据库名称即可,mongodb会自动帮你创建数据库,同时起到切换数据库的作用</p>
|
||
</blockquote>
|
||
<p>在mongodb中没有我们通常说的”表”的概念,与表相对应的是”collection”,我们通常做到增删查改都是都与一个数据库中的collection而言的,在mongodb中不需要特意创建collection,如果我们使用的是一个没有的collection,系统便会自动创建</p>
|
||
<p>比如我们想插入一条数据:</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">db.mycollection.save({"name":"junv"});
|
||
|
||
</pre>
|
||
|
||
<p>系统便会自动生成名为mycollection的collection,并将数据存入其中.</p>
|
||
<p>我们也可以使用下面的话来达到同样的效果:</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">var tom = {"name": "junv"};
|
||
|
||
db.mycollection.save(tom);
|
||
|
||
</pre>
|
||
|
||
<p>我们可以使用 show collections 在查看当前数据库中所拥有的所有collection列表.</p>
|
||
<p>我们需要使用db.mycollection.find() 来查询其中的数据,如果我想查询”name” 为mary 的数据,就需要使用:</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">db.mycollection.find({"name":"mary"});
|
||
|
||
</pre>
|
||
|
||
<p>在一个collection 中,我们可以插入不同的数据,比如在mycollection中,我们还可以插入:</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">db.mycollection.insert({"city":"chegndu","nation":"china"});
|
||
|
||
</pre>
|
||
|
||
<p>这正是mongodb带来的优势.</p>
|
||
<p>如果我们查查询若干条数据,或者查询从n到m条数据,就需要使用:</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">db.mycollection.find().limit(n);
|
||
|
||
db.mycollection.find().limit(n,m)
|
||
|
||
</pre>
|
||
|
||
<p>当查询的数据过多而显示不完是,我们就需要使用 it 命令,来显示剩余部分.</p>
|
||
<p>更新数据，比如我们将“name”为mary的改为lily</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">var temp = db.mycollection.find({"name":"mary"});
|
||
|
||
temp.name = "lily"; //改变名字
|
||
|
||
db.mycollection.update({"name":"mary"},temp); //保存
|
||
|
||
</pre>
|
||
|
||
<p>删除数据,将lily这条数据删除：</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">db.mycollection.remove({"name":"lily"});
|
||
|
||
</pre>
|
||
|
||
<p>删除所有数据:</p>
|
||
<pre class="brush: sql; title: ; notranslate" title="">db.mycollection.remove({})
|
||
|
||
</pre>

<p>平时在使用maven下载依赖或者maven插件的时候，经常被本地仓库，settings里面profile中设置的仓库，mirror仓库，pom文件中的repository搞疯，因为很可能你就会因为这些你所设置的仓库不能正常编译项目。下面将和大家一起探讨和比较下这几种仓库的优先级别。</p>
|
||
<p>这里我们有三个仓库 ：</p>
|
||
<ul>
|
||
<li>远程222.197.xxx仓库</li>
|
||
<li>localhost镜像，是我自己在本机搭建的一个仓库</li>
|
||
<li>nexus仓库，是nexus官方的仓库</li>
|
||
</ul>
|
||
<p>首先考虑这样一种情况：maven本地仓库中拥有该包，而中央仓库、mirror仓库、profile仓库、pom中仓库均不含该包。我们可以看到maven直接首先从本地仓库中找到该包，编译成功。</p>
|
||
<p><a href="/images/2012/07/1.png"><img class="aligncenter size-large wp-image-2083" title="1" src="/images/2012/07/1-1024x267.png" alt="" width="1024" height="267" /></a></p>
|
||
<p>由此可以看出，本地仓库拥有最高的优先级。</p>
|
||
<p>接下来，我们继续剩下的仓库的优先级，（下面所有情况，都默认本地不拥有我们需要的包）剩下的仓库都是远程仓库，这里我们设定mirror设置的镜像仓库是中央仓库的镜像。那么就可以把mirror当成中央仓库，因为其已经被mirror替换了。</p>
|
||
<p>这次的场景为：pom文件中定义的仓库（repository）（即远程：222.197.xxx）拥有该包，而mirror(localhost镜像)和profile（nexus仓库）中的仓库不拥有该包。进行测试：</p>
|
||
<p><a href="/images/2012/07/2.png"><img class="aligncenter size-large wp-image-2087" title="2" src="/images/2012/07/2-1024x267.png" alt="" width="1024" height="267" /></a></p>
|
||
<p>从这个结果可以看出，maven首先调用了profile中的仓库，其次找到了pom文件中设置的仓库。而mirror没有出现。我们这里可以初步推测优先级别为：profile > pom > mirror，为了验证我们的判断，我们需要在进行一次测试来验证这个结果。</p>
|
||
<p>场景如下：mirror中拥有该包（222.197），而pom(localhost镜像)和profile（nexus仓库）中均不含有该包。进行测试：</p>
|
||
<p><a href="/images/2012/07/3.png"><img class="aligncenter size-large wp-image-2089" title="3" src="/images/2012/07/3-1024x319.png" alt="" width="1024" height="319" /></a></p>
|
||
<p>实际情况的确验证了我们的猜想。那么我们得出这几种maven仓库的优先级别为：</p>
|
||
<blockquote>
|
||
<p>本地仓库 >profile > pom中的repository > mirror</p>
|
||
</blockquote>
|
||
<p>注意：我也验证过这样的情况，将mirror这样设置：</p>
|
||
<pre class="brush: xml; title: ; notranslate" title=""><mirror>
|
||
<id>huacloud-central</id>
|
||
<mirrorOf>*</mirrorOf>
|
||
<name>name-of-this</name>
|
||
<url>http://222.197.XXXXXX/nexus/content/groups/public/</url>
|
||
</mirror>
|
||
</pre>
|
||
|
||
<p>即是表示该仓库地址为所有仓库的镜像，那么这个时候，maven会忽略掉其他设置的各种类型仓库仓库，只在mirror里面找。所以建议不要这样设置，他将导致pom文件中、pforile里面的仓库设置都失效。</p>

|
||
<p>pom中的repository:</p>
|
||
<pre class="brush: xml; title: ; notranslate" title=""><repositories>
