JQuery controls the iFrame of instance code

Get the value of an element of the parent window in the IFRAME with jQuery DOM method and jquery method to combine the way to achieve

**1. In the parent window, select all radio buttons in the IFRAME **$(window frames [r]. “iframe1” document), find (” input [@ type = ‘radio’] ”). Attr (” checked ”, “true”);

**2. Operate all the radio buttons in the selected parent window in the IFRAME **$(window. The parent. The document). Find (” input [@ type = ‘radio’] ”). Attr (” checked ”, “true”);

Iframe:

< Iframe SRC = “test.html” id= “iframe1” width= “700” height= “300” frameborder= “0” scrolling= “auto” > < / iframe>

IE7 passed the test

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >

    <title>jQuery control iframe</title>
    <script type="text/ecmascript" src="../js/jquery-1.2.6.js"></script>
    <script type="text/javascript">
        $(function(){
            $("#t1").hover(function(){alert('');});
            //$("iframe").contents().find("body").append("I'm in an iframe!");
            //$(window.frames["iframe1"].document).find("input[@type='text']").attr("size","30px");
            //$("#iframe1").contents().find("#d1").css('color','red');
            //$(window.frames["iframe1"].document).find("input[@name='t1']").css({background:"#369"});
            //$("#iframe1").src("test.html");
        });
    </script>
</head>
<body>
<div>
<input type="text" id="t1" />
<iframe id="iframe1" src="child.htm"></iframe>
<iframe src="child.htm" width="300" height="100"></iframe>
</div>
<div>
</div>
</body>
</html>

Use jquery to manipulate the iframe

There are two ifame in the content

< The iframe id = “leftiframe”… < / iframe> < The iframe id = “mainiframe.. < / iframe>

JQuery in leftiframe changes the SRC code of mainiframe: $(” # mainframe ”, the parent. The document. The body). Attr (” SRC ”, ”/ / www.jb51.net”)

**2. If the content contains an ifame with the ID mainiframe **< The iframe id = “mainifame”… > < / ifame> Ifame contains a someID < Div id = “someID” > You want to get this content< / div> Get the content of someID

$(” # mainiframe ”). The contents (.), find (” someID ”). The HTML () HTML or $(” # mainiframe ”). The contains (). The find (” someID ”). The text () value

3. In the parent window, select all radio buttons in the IFRAME $(window frames [r]. “iframe1” document), find (” input [@ type = ‘radio’] ”). The attr (” checked ”, “true”);

The natural choice for id is to still use the find method $(window frames [r]. “iframe1” document), find (” # id ”)
