Javascript e.keyCode doesn't catch Backspace/Del in IE

Question

I\'m trying to catch the pressing event of Backspace and Delete keys using javascript/jQuery with this kind of code.

$(\"textarea[name=txt]\").keypress(funct         


        

Answer 1

Key Code for Backspace will take the value = 83 if we already have a few characters in a Text Box .

The Key Code will be = 8 if there are NO Characters in the Text Box and we are trying to Hit Backspace.

Answer 2

If you want to support IE and you use special keys (like delete and backspace) I suggest using keydown/keyup instead.

Special keys

Explorer doesn't fire the keypress event for delete, end, enter, escape, function keys, home, insert, pageUp/Down and tab.

If you need to detect these keys, do yourself a favour and search for their keyCode onkeydown/up, and ignore both onkeypress and charCode.
