[javascript] Javascript Iframe innerHTML

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; 

  }
