[jQuery] Detect Enter event with Jquery on Linux

[Shi Zhuguo]

Hi there,

I am using jquery to make a Comet chat client. But I have problems to
detect "press enter" event on Linux. It's really strange. The same
code runs well on windows:

j.input.bind("keydown", function(l) {
                 if (l.keyCode == 13) {
                        //doing some stuff here, like sending the
message

Any suggestions?
