装入一个远程HTML内容到一个DOM结点。

注意：避免用装入的scripts脚本，装入脚本改用$.getScript.当任何字符显示时，IE会忽略所有的脚本。

返回值：jQuery

参数：

• url (String): 装入的HTML文件url地址
• params (Object): （可选）发送到服务端的键／值对参数。
• callback (Function): （可选） 当数据装入完成时执行的函数.

示例：

$("#feeds").load("feeds.html");

HTML 代码:

<div id="feeds"></div>

结果:

<div id="feeds"><b>45</b> feeds found.</div>

示例：

和上面相似，但加入了当数据装入后执行一个回调函数参数。

$("#feeds").load("feeds.html",
  {limit: 25},
  function()   {
   alert("The last 25 entries in the feed have been loaded");
  } 
); 

Load HTML from a remote file and inject it into the DOM.

Note: Avoid using this to load scripts, instead use $.getScript. IE strips script tags when there aren't any other characters in front of it.

Return value: jQuery
Parameters:

• url (String): The URL of the HTML file to load.
• params (Object): (optional) A set of key/value pairs that will be sent as data to the server.
• callback (Function): (optional) A function to be executed whenever the data is loaded (parameters: responseText, status and response itself).

Example:

 $("#feeds").load("feeds.html");  

 <div id="feeds"></div>  

 <div id="feeds"><b>45</b> feeds found.</div>

Example:

Same as above, but with an additional parameter and a callback that is executed when the data was loaded.

 $("#feeds").load("feeds.html",
     {limit: 25},
     function() {
       alert("The last 25 entries in the feed have been loaded");
     }   
 );
