Thank for all of your idea. With your advice, I finally work out this question with my friends. The solution is as
followed.
We find that “window" is one of the object in JavaScript, which can operate the element in "iframe". So you can use it to locate the tag in an embedded web page.
top
"top" is an attribute in the object window. By using the statement "window.top", you can get the top window in the web page. and then
Using the statement"window.top.iframe" to get the iframe object .
get the next iframe tag by object "document"
attribute "contentDocument" in iframe can be used to return the current document object. and then you can find the next iframe using the statement"window.top.iframe.contentDocument.getElementsByTagName('iframe')[0]"!
