How to highlight some text in an iframe by script?

mylittlejava 2004-11-23 12:46:59

hi, all
I have an iframe in my page. Actually what I want is just like the google search.
When user clicks search, I will load the a page from another URL into iframe and then highlight the key words in the iframe.
Does anyone know how to do this? By JS or VBScript?

Thanks

first one
if the page you load is not in your own domain, you cant change its content and you
can use xmlhttp parse the source code, then do what you want.

second
the page you load in your own domain, the you can do it by the follow way

var str = window.frames['iframeName'].document.body.innerHTML;
str = str.replace("keyword", "<span style='color:red'>keyword</span>");
window.frames['iframeName'].document.body.innerHTML = str;
