onBlur global event

[robdon]

Hi,

While I'm running an Ajax query, I'm trying to disable the user from moving to other fields on the form.

So, I need a 'global' onBlur event to set focus back to the currect field which its running.

I've tried the following at the start of my code, where I define other global events (that work fine) like onClick & oncontextmenu...

document.onBlur = myBlurProc;

But it doesnt seem to fire on any of my controls.

Anyone know how I can dynamically attach a onBlur event to all of my fields.

Thanks,

Yes - loop over all of the fields you want to attach the event to, and attach it to them one at a time.

Hope this helps,
Dan

Hi,

Thanks for that, but I dont really want to do that.

There has to be a global method, surely??

Really, looping through all elements and attaching an event isnt the best for performance, IMO.

That's odd, because it's exactly what you asked for:

Why does there have to be?

How many elements are we talking here? Have you tried it? How long did it actually take? IMO, anything less than [picks an arbitrary number] 100, then it should take a fraction of a second.

AFAIK, there is no other way.

why noy just include the on blur for each element in the html source code?
(if html is generated serverside it should still be possible to include it here.)

Because it's considered bad practice to do so, not least because those without JS have to download extra bytes that having an external script file would negate.
