在html5中有个支持跨域传递的方法postMessage，可是实现iframe之间的数据传递！
代码如下：数据发送页面
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="utf-8"/>
<meta name="copyright" content=""/>
<meta name="keywords" content=""/>
<meta name="description" content=""/>
<title></title>
</head>
<body>
<div class="color">
<input type="text" value="" class="getColor"/>
<input type="button" id="button" value="发送颜色" />
</div>
<iframe id="child" src="http://localhost/send/index.html" width="400" height="300"></iframe>
</body>
</html>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script>
$(function(){
$("#button").click(function(){
var color = $(".getColor").val().toString();
window.frames[0].postMessage(color,‘http://localhost/send/index.html‘);
});
});
</script>
数据接收页面
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="utf-8"/>
<meta name="copyright" content=""/>
<meta name="keywords" content=""/>
<meta name="description" content=""/>
<title></title>
</head>
<body>
<div id="color" style="width:400px;height:200px;">
</div>
</body>
</html>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script>
$(function(){
var color = $("#color");
window.addEventListener(‘message‘,function(e){
var s_color=e.data;
color.css(‘background-color‘,‘#‘+s_color);
},false);
});
</script>
当在发送页面改变颜色值的时候，嵌入的iframe的页面背景色直接就被修改了，效果很好！
