[Moo] selections in Meio.Mask.Reverse

[Robert]

Hey,
I am using great script by Fabio Costa "Meio.Mask.Reverse".
I had some problems with selection functionality: after selecting
everything in the box and pressing "delete" or "backspace" or some
number value wasn't cleared, instead the number was added in the end
of the number (or delete last number).
In jquery version of the script it looks like everything is working
ok:

I made a fast remedy for my client in keypress method:
        //previous:
        //elementValue = o.isRemoveKey ? elementValue.substring(0,
elementValue.length - 1) : this.getValue(elementValue + _char);
        //my solution:
        var selectionRange = this.element.getSelectedRange();
        var selStart = selectionRange.start;
        var selEnd = selectionRange.end;
        if (selStart < selEnd) {
            elementValue = elementValue.substring(0, selStart) +
elementValue.substring(selEnd, elementValue.length);
        }
        if (o.isRemoveKey) {
            if (selStart === selEnd) {
                elementValue = elementValue.substring(0,
elementValue.length - 1);
            }
        } else {
            elementValue = this.getValue(elementValue + _char);
        }

But maybe there is a better way to do this? Or am I missing something
and it shouldn't be done at all?


Happy Easter!
Robert
