How can I add content to a page after opening the link in a new window/tab?

Question

I'm trying to add some content into a page that is opened in a new tab/window, and nothing seems to be happening. Here is some of my code:

var newWindow = window.open('/Window');
newWindow.document.body.innerHTML += '<div>This is a test</div>';

Any ideas?

Answer 1

as you have tagged jquery:

var w = window.open();
var html = '<div>This is a test</div>';
$(w.document.body).html(html);
