Status: RESOLVED DUPLICATE of bug 787102

(Firefox :: Untriaged, defect)

Description

[huhufleisch]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:10.0.6) Gecko/20120717 Firefox/10.0.6
Build ID: 20120717200345

Steps to reproduce:

I have a function in JS that make a mask to an input. This mask it's just a format for brazilian money.
It work's well from firefox 4, and now(), at 15 branch, it's doesn't work anymore.


Actual results:

The event onchange does not fired when I use the event onkeyup to change the value of the input.
look the code(it's veeeeeery simple):
<input type="text" onkeyup="this.value=this.value+'-';" onchange="alert('change executed');">



Expected results:

the event onchange must be fired.
At firefox 10, I'm sure that this work, because I have this version on my linux.
At Chrome versions 15 to 22, it works too.

The problem was found at linux(Fedora) and windows(xp and seven).
