jQuery: how to filter out non-character keys on keypress event?

Asked 2010-02-17T22:20:17.453

I tried searching but unsure of what terms to look for.

I'm using jQuery and would like to use the keypress event in a textbox, but prevent all non-printable characters (ie. Enter, ESC, arrow keys, backspace, tab, ctrl, insert, F1-F12, etc) from triggering the event.

Is there an easy way to determine if it is printable?

You can use regular expressions like this

$('something').keypress(function(e) {
    if(e.match(YourRegularExpressionHere)) {
        //do something
    } 
});

This will only do something if it matches the regular expression.

Have a look at regular expressions. http://www.regular-expressions.info/javascript.html
