“IndexSizeError” when using Selection.getRangeAt on IE
while running window.getSelection().getRangeAt(0) on contenteditable div on modern browsers work as expected,
Internet Explorer throws an "IndexSizeError" exception on some cases.
It happens when the AnchorNode of the Selection object is a TextNode and not a HTML node.
I thought maybe I would find a polyfill for that but none seems to be existing.
Is there any quick solution for that or an alternative for using getRangeAt()?

I discovered that the same thing happens on Safari Mobile:
IndexSizeError: The index is not in the allowed range.
I found this post about it:
Creating a Range object from a Selection object on Safari
with this code:
var rangeObject = getRangeObject(userSelection);
function getRangeObject(selectionObject) {
if (selectionObject.getRangeAt)
return selectionObject.getRangeAt(0);
else { // Safari!
var range = document.createRange();
range.setStart(selectionObject.anchorNode,selectionObject.anchorOffset);
range.setEnd(selectionObject.focusNode,selectionObject.focusOffset);
return range;
}
}
After some adjustments for my need:
var range = document.createRange();
if(selectionObject.anchorNode) {
range.setStart(selectionObject.anchorNode ,selectionObject.anchorOffset);
range.setEnd(selectionObject.focusNode,selectionObject.focusOffset);
}
else {
range.setStart(div_element ,selectionObject.anchorOffset);
range.setEnd(div_element, selectionObject.focusOffset);
}
The condition is for a case where the div is empty and anchorNode is null - so in that case it should use the div_element itself.
if there is anchorNode (including TextNode type), the first part works well also on IE and safary mobile.
