Get selected text with JS - even in iFrames

Question

Right now i get the selected text with window.getSelection().toString(). But unfortunately this doesn't work for text in iFrames. It's for a chrome extension, so i don't need to hear about how iFrames suck ;).

Answer 1

If you have a reference to the iframe in question then

iframeEl.contentWindow.getSelection().toString();

... will do the job. If you want to get the selected text from all iframes, you could use window.frames, which is a collection of Window objects rather than frame/iframe elements:

var selectedTexts = [];
Array.prototype.forEach.call(window.frames, function(frameWin) {
    selectedTexts.push( frameWin.getSelection().toString() );
});
