使用jQuery.load方法加载一个网页，那么这个网页内部的js代码是否能够执行呢，答案是肯定的，这就相当于把load的内容与主页面进行了合并一样，只要不冲突（例如id不能一样），我写了一个例子，利用页面参数控制内部的元素id，互相加载自己。这是一个jsp页面，代码如下：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
int i = Integer.parseInt(request.getParameter("i")==null?"0":request.getParameter("i"));
%>

<base href="<%=basePath%>">

<script type="text/javascript" src="<%=path%>/Scripts/jquery-1.5.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#h<%= i %>").click(function(){
$("#d<%= i %>").load("<%=basePath%>index.jsp",{i:<%=i+1%>});
});
});
</script>
</head>
<body>
this is index.jsp?i=<%= i %>
<input type="button" value="get<%= i+1 %>" id="h<%= i %>">
<br>
<div id="d<%= i %>" style="border:1px; border-style: solid; margin: 5px;">load index.jsp?i=<%= i+1 %> here!</div>
</body>
</html>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
int i = Integer.parseInt(request.getParameter("i")==null?"0":request.getParameter("i"));
%>

</body>
</html>
运行后如图所示，可以一直点下去：
但是，如果你只取的是页面的一部分，例如将按钮的点击代码改成：
$("#d<%= i %>").load("<%=basePath%>Login.action input",{i:<%=i+1%>});
那么，加载的就只是一个按钮了，而不是整个页面。如图：
