Javascript function replace instead of write

Question

function sethtml(a,b)
{
    var x = document.getElementById("canvas_html").contentDocument; x.write(b);
}

This works but I want to replace the content instead of writing to it.

Is `x` supposed to be an iframe? More detail is needed here. — Chris Hayes, Nov 12 '12 at 16:34

x.innerHTML = b;

This will replace entirely the contents of x for ordinary DOM elements. In the case of an iframe, see this question for details on how to clear an iframe. You could then simply use the write method to add your new content.

Ended up with `function sethtml(a,b) { var doc = document.getElementById("canvas_html"); if( doc.document ) { document.test.document.body.innerHTML = ""; //Chrome, IE }else { doc.contentDocument.body.innerHTML = ""; //FireFox } doc.contentDocument.write(b); }` – Max0999 Nov 12 '12 at 16:47
