Description

10 years ago
User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

I have code for dragging over a text area that updates the selected area that works in IE (v_elText is the text area element):

var rng = v_elText.createTextRange();
rng.moveToPoint( e.x, e.y );
rng.select();

Since that doesn't work for Firefox, I wrote the following code that works in Firefox2:

var offset = e.rangeOffset;
offset = this.f_findLocation(e.rangeParent, e.rangeOffset);
v_elText.setSelectionRange( offset, offset );

where f_findLocation is following:

f_findLocation = function(elem, offset) {
while(elem.previousSibling)
{
	elem = elem.previousSibling;
	if (elem.length)
		offset += elem.length;
	else
		offset += 1;
}
return offset;
}

I try this in Firefox 3 and I get permission denied exception when attempting to access rangeParent.previousSibling.


On debugging, I see that in Firefox 2 rangeParent is a Text object as expected. In Firefox 3 rangeParent points to 
a HTMLDivElement (that presumably wraps the text area)
The error specifically is "Permission denied to get property HTMLDivElement.previousSibling"

Is this a bug (rangeParent not pointing to Text object in Firefox 3)?

Reproducible: Always

Steps to Reproduce:
1.
2.
3.
Actual Results:  
evt.rangeParent points to HtmlDivElement object

Expected Results:  
evt.rangeParent points to Text object
If you attach a testcase someone can test what bug fix is responsible for the regression.

The HTMLDivElement is the anonymous div for the textarea in this case.  Hard to say what the right rangeParent is offhand without the testcase Ria asked for.
We are facing the same problem in Firebug. The test case can be found here:
