how to load HTML in DIV

I have one JSP page with two DIVs , one DIV to display the content and other to work as menu. In content DIV, I want to load the external HTML page. and I need to call some Java script function of content HTML (loaded in content DIV) to perform some function. When i am using :
document.getElementById("content").innerHTML =xmlhttp.responseText

innerHTML does not return the HTML page.

Can someone please let me know how I can load external HTML in my content DIV and also i can access their Java script function.

An HTML Page? As in, complete with the <html> tag and everything? If so, then you cannot. It is not valid to include an <html> element anywhere inside the DOM.

If you meant an HTML fragment, that's different.

Which do you mean?

DIV content will have the linked to Javascript , CSS files and images.. no HTML tag.

The just an HTML fragment, not a "page" (for that, you'd have to use an iframe).

So now you need to explain how you are "loading" the fragment and what you mean by "innerHTML does not return the HTML page".

And, this doesn't seem like a JSP problem at all, so I've moved this to the HTML forum.
