Obtain selected text from IFRAME using Rangy

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?

Solution

  • 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.
