2)在iframe中调用父页面中定义的方法和变量:
parent.method
parent.value
3)实例
1.父页面
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="IframeDemo._Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " <html xmlns="www.w3.org/1999/xhtml" ><head runat="server"> <title></title> <script language="javascript" type="text/javascript" src="jquery-1.5.1.min.js"></script> <script language="javascript" type="text/javascript"> var hello = 'hello'; function getHelloWorld() { alert('hello world'); } </script></head><body> <form id="form1" runat="server"> <div> <div id="default" style=" width:200px; height:400px; float:left;">default.aspx</div> <iframe id="iframeid" src="IFrame.aspx" style=" width:400px; height:400px; float:left;"> </iframe> </div> </form> </body></html>
2.子页面
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="IFrame.aspx.cs" Inherits="IframeDemo.IFrame" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " <html xmlns="www.w3.org/1999/xhtml" ><head runat="server"> <title></title> <script language="javascript" type="text/javascript" src="jquery-1.5.1.min.js"></script> <script language="javascript" type="text/javascript"> $(function() { //在iframe中查找父页面元素 alert($('#default', window.parent.document).html()); //在iframe中调用父页面中定义的方法 parent.getHelloWorld(); //在iframe中调用父页面中定义的变量 alert(parent.hello); }); </script></head><body> <form id="form1" runat="server"> <div id="iframe"> IFrame.aspx </div> </form> </body> </html>
