Question

what i want to do is ensure that ” ‘ are characters that do not get typed into the input box I have a variety of key-press codes that restrict users to a-z and 0-9 but some how i cannot seem to make it work in a manner that i can restrict to not typing a few characters rather than specifying what needs to be typed.

http://jsfiddle.net/cG4aV/ – tryign to restrict enter key (works) , ” ‘ (does not work)

it also does not work for any key that activates with a shift…

any ideas

Answer 1

I see it works on Chrome, but not on Firefox. Try replacing keyCode for which, it’s normalized for all browsers.

Updated fiddle, should work in both browsers now.

Quoting jQuery docs on event.which:

The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input. For more detail, read about event.charCode on the MDC.

So, it’s enough to test for which, no need to check keyCode or charCode.
