jQuery Ajax 全解析【.ajax .post .get】 14 December 2009 13:03 Monday by 小屋 浏览(3631)

1. load( url, [data], [callback] ) ：载入远程 HTML 文件代码并插入至 DOM 中。

url (String) : 请求的HTML页的URL地址。

data (Map) : (可选参数) 发送至服务器的 key/value 数据。

callback (Callback) : (可选参数) 请求完成时(不需要是success的)的回调函数。

这 个方法默认使用 GET 方式来传递的，如果[data]参数有传递数据进去，就会自动转换为POST方式的。jQuery 1.2 中，可以指定选择符，来筛选载入的 HTML 文档，DOM 中将仅插入筛选出的 HTML 代码。语法形如 "url #some > selector"。

这个方法可以很方便的动态加载一些HTML文件，例如表单。

示例代码：

$(".ajax.load").load("http://www.cnblogs.com/QLeelulu/archive/2008/03/30/1130270.html .post",
		function (responseText, textStatus, XMLHttpRequest){
		this;//在这里this指向的是当前的DOM对象，即$(".ajax.load")[0]	
		//alert(responseText);//请求返回的内容
		//alert(textStatus);//请求状态：success，error
