能读frame里的BODY里的内容吗?
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN " "http://www.w3.org/TR/html4/frameset.dtd ">
<html xmlns= "http://www.w3.org/1999/xhtml ">
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=utf-8 ">
<title> 无标题文档 </title>
<script> alert(document.getElementsByTagName( 'mainFrame ').body) </script>
</head>
<frameset rows= "80,* " frameborder= "NO " border= "0 " framespacing= "0 ">
<frame src= "UntitledFrame-2.html " name= "topFrame " scrolling= "NO " noresize title= "topFrame " >
<frame src= "Untitled-1.html " name= "mainFrame " title= "mainFrame ">
</frameset>
<noframes> <body>
</body> </noframes>
</html>
[解决办法]
可以
window.frames[ "frame_name "].document.body就可以获得frame的页面的body对象
读内容可以用window.frames[ "frame_name "].document.body.innerHTML
