How to get a Javascript routine to NOT act if it's in a text box?

Question

I've got a simple page, and in that page runs a simple jquery keypress routine to catch clicks of the numbers 1 to 9 (has to be that to pass RNIB accessibility test).

And in that page is a form, which can have numbers entered as part of a postcode.

Scroll to the bottom, try typing 8 or 9 for example. The text is entered, but it also acts on the keypress. Expected, but not good.

I'm aware of various things like document.getElementById, but I can't figure out how to put these together to ensure that while the cursor is in the text input box, it doesn't act out the keypress catcher.

Answer 1

The target property of the event object (the parameter to the handler function) will tell you which element actually generated the event.

You need to check whether e.target is an <input> element, like this:

if ($(e.target).is(':input'))
    return;
