Can more than one JavaScript handler register to an event?

Question

Can more than one JavaScript handler register to an event such as window.onresize? I tried using +=, but that had no effect. Only = and that obviously replaces any previously assigned events.

Answer 1

For IE you can use: window.attachEvent('onresize', handler);

where handler is your handler function.

In all other browsers you can use: window.addEventListener('resize', handler);

Both of these functions can be used multiple times to attach multiple event handlers.
