I have iframe with id="iView" and designMode = on.

My code: 

 var iframeWindow = document.getElementById('iView').contentWindow.document;                                                                                            
 var range = iframeWindow.getSelection().getRangeAt(0);

The Error I get:

Microsoft JScript runtime error: Object doesn't support this property or method

I also tried answers from
how to get selected text from iframe with javascript?

There is no getSelection method for the document object in IE, you have to use the selection object instead.

var selText;
var iframeWindow = document.getElementById('iView').contentWindow;
if (iframeWindow.getSelection)
    selText = iframeWindow.getSelection()+"";
else if (iframeWindow.document.selection)
    selText = iframeWindow.document.selection.createRange().text;

  • why there is need to check iframeWindow.getSelection or iframeWindow.document.selection? – samuel Dec 09 '09 at 22:43
  • You're checking the functionality exists, which is essentially a browser check. If the browser doesn't support the method, those statements would return false and the script wouldn't execute - if the checks weren't there and the browser doesn't support the method an error is thrown. Alternatively, you could use a try/catch statement but this is usually the defacto method of functionality testing. – Andy E Dec 09 '09 at 22:54

    @samuel: This is a perfectly good answer but pretty much identical to a couple found in the other question you mentioned (http://stackoverflow.com/questions/1471759/how-to-get-selected-text-from-iframe-with-javascript), so how has this given you new information? – Tim Down Dec 10 '09 at 10:40
  • lol just checked and it's most identical to your own answer in that question. Sorry if it seems like I duplicated it (I didn't) :-) +1 for it anyway. – Andy E Dec 10 '09 at 11:16
  • @Andy E: I wasn't making a particular case for my answer and I didn't think you'd duplicated it because the style's slightly different, but thanks for the upvote :) – Tim Down Dec 10 '09 at 14:11
