jquery、js调用iframe父窗口与子窗口元素的方法
2、父窗口调用子窗口：myFrame.window.functionName();
3、子窗品调用父窗口：parent.functionName();
简单地说,也就是在子窗口中调用的变量或函数前加个parent.就行
4、父窗口页面源码：
<html> <head> <script type="text/javascript"> function say() { alert("parent.html------>I'm at parent.html"); } function callChild(){ //document.frames("myFrame").f1(); myFrame.window.say();} </script> </head> <body> <input type=button value="调用child.html中的函数say()" onclick="callChild()"> <iframe name="myFrame" src="child.html"></iframe> </body> </html>?5、子窗口页面：
<html> <head> <script type="text/javascript"> function say() { alert("child.html--->I'm at child.html"); } function callParent() { parent.say(); } </script> </head> <body> <input type=button value="调用parent.html中的say()函数" onclick="callParent()"> </body> </html>?
二、iframe 父窗口和子窗口相互的调用方法
1、IE中使用方法：
父窗口调用子窗口：iframe_ID.iframe_document_object.object_attribute = attribute_value<HTML> <HEAD> <TITLE> Test Page </TITLE> <script src="prototype-1.4.0.js"></script> <script language="javascript"> function show() { window.frames["iframe_text"].document.getElementById("myH1").innerHTML = "http://hi.wonsoft.cn"; } </script> </HEAD> <BODY> <iframe height="350" width="600" src="iframe_test.htm" name="iframe_text"></iframe> <form action="" method="post"> <input name="haha" id="haha" type="text" maxlength="30" value="haha" /> <br /> <textarea cols="50" rows="5" id="getAttributeMethod"></textarea> <input type="button" onClick="show();" value="提交"/> </form> <h1 id="myH1">d</h1> </BODY></HTML>
