Obtain selected text from IFRAME using Rangy

Question

I am trying to get selected text of Iframe using Rangy using this function;

function getSelectedText() {
   var iframe = document.getElementById("CustomeHTMLViewer");
   var iframeWin = iframe.contentDocument ? iframe.contentDocument.defaultView : iframe.contentWindow;
   var sel = rangy.getSelection(iframeWin);
   return sel;
}

This code is not working; how can I get selected text of an Iframe?

Answer 1

Rangy has a convenience method for this: rangy.getIframeSelection(). Example:

var iframe = document.getElementById("CustomeHTMLViewer");
var sel = rangy.getIframeSelection(iframe);

To get hold of the selected text, call toString() on the selection:

var selectedText = sel.toString();
alert(selectedText);

Rangy allows an iframe element to be passed directly into rangy.getSelection().

Having said all that, there doesn't actually seem to be anything wrong with your original code.
