将iframe中的html内容复制到div（ajax）中？

Question

Lets assume I have my browser load an Iframe with <iframe src="test.html">

Can I, using ajax, load the content of test.html into a div in the main html page?

This idea is my solution for that fact that I'm actually trying to overcome the limitation with making ajax submits to remote hosts. The plan is to generate the dynamic page with 0 sized iframe which makes report request to remote host. Then, after the page (& iframe content) loads I will copy the iframe content into a div using JS.

Tips are appreciated,

Thank you, Maxim.

Answer 1

No, you can't.

When you load a page from a different domain into the iframe, it becomes unreachable. You can no longer access the contents of the iframe, as it comes from a different domain.

The only thing that I know of that you can reliably load from a different domain is a script, which JSONP uses.

Yes (since your example has a relative URI and is on the same host) …

… and no. You still can't read data from remote hosts.

I'm sure someone will correct me if I'm wrong, but I believe that scripting across domain boundaries is restricted. Have you tried it? Here's a function that may help out.

function insertDivFromFrame(divname, framename) {
    var frame = document.getElementById(framename);
    var d = frame.contentWindow || frame.contentDocument;
    if (oDoc.document) {d = d.document;}
    document.getElementById('yourdiv').innerHTML = d.body.innerHTML;
}

I'm not sure this code works... see http://xkr.us/articles/dom/iframe-document/ for more help on this.

...您可能，但是，设计一个AJAX请求到本地主机和检索远程服务器的信息（如描述在这里 ）。

Answer 5

If you write a php/perl/etc. script to output the contents of a document from another domain, it'll give you access to the contents as the resulting page would be considered by javascript to belong to your domain. If you're not familiar with any server-side scripting languages, I'm sure you'd be able to find a script that'll do this for you by doing a simple google search.

Best of luck.
