Javascript Iframe innerHTML

Does anyone know how to get the HTML out of an IFRAME I have tried several different ways:

document.getElementById('iframe01').contentDocument.body.innerHTML
document.frames['iframe01'].document.body.innerHTML
document.getElementById('iframe01').contentWindow.document.body.innerHTML

etc

Solution 1:

I think this is what you want:

window.frames['iframe01'].document.body.innerHTML 

EDIT:

I have it on good authority that this won't work in Chrome and Firefox although it works perfectly in IE, which is where I tested it. In retrospect, that was a big mistake

This will work:

window.frames[0].document.body.innerHTML 

I understand that this isn't exactly what was asked but don't want to delete the answer because I think it has a place.

I like @ravz's jquery answer below.

Solution 2:

Having something like the following would work.

<iframe id = "testframe" onload = populateIframe(this.id);></iframe>

// The following function should be inside a script tag

function populateIframe(id) { 

    var text = "This is a Test"
var iframe = document.getElementById(id); 

var doc; 

if(iframe.contentDocument) { 
    doc = iframe.contentDocument; 
} else {
    doc = iframe.contentWindow.document; 
}

doc.body.innerHTML = text; 

  }

Solution 3:

If you take a look at JQuery, you can do something like:

<iframe id="my_iframe" ...></iframe>

$('#my_iframe').contents().find('html').html();

This is assuming that your iframe parent and child reside on the same server, due to the Same Origin Policy in Javascript.

Solution 4:

Conroy's answer was right. In the case you need only stuff from body tag, just use:

$('#my_iframe').contents().find('body').html();
