dom - How do I write content to another browser window using Javascript?

Question

I've opened a new window with window.open() and I want to use the reference from the window.open() call to then write content to the new window. I've tried copying HTML from the old window to the new window by using myWindow.document.body.innerHTML = oldWindowDiv.innerHTML; but that's doesn't work. Any ideas?

Answer 1

The reference returned by window.open() is to the child window's window object. So you can do anything you would normally do, here's an example:

var myWindow = window.open('...')
myWindow.document.getElementById('foo').style.backgroundColor = 'red'

Bear in mind that this will only work if the parent and child windows have the same domain. Otherwise cross-site scripting security restrictions will stop you.
