input.val() interprets null as 'null' in IE7

Reported by: zirouk Owned by:
Priority: minor Milestone: 1.3.2
Component: attributes Version: 1.3.1
Keywords: Cc:
Blocking: Blocked by:


If I set the value of an input box with .val(null), IE7 inserts the string 'null' into the input. Firefox 3 correctly sets the input to .

1.2.1 correctly set the value to in both ie7 and ffx3 when using .val(null)

I will attach a html file containing a small demo and hotswap 1.2.1 and 1.3.1.

hmm Trac evaluated my double single quotes incorrectly.

Where bad grammar exists describing output, please assume null or empty string.

Fix: core.js Line 389 change to:

if ( value === null
value === undefined ) {

Again, Trac butchered it, I'm sure you're smart enough to work it out.
