Currently researching Blackberry Browser software solution and have found an issue.  I am creating a html input text via asp.net and attach an onchange event to the list.  Upon onchange I simply want to display the id of the text box that generated fired the onchange

Attempts made....

alert(Event.currentTarget); = empty alert

alert(Event.currentTarget.id);= no alert.  I assume an exception is thrown behind the scence.

Anyone from RIM care to comment?  How can I get the id of the element that triggered the event?  The preferred method would be W3C compliant.

Thanks,

smorton

"Event.currentTarget" is not W3C-compliant. Something like "e.currentTarget" would be, if e were the event object passed to the event handler. What does your actual HTML look like?

Using an external js file this seems to work.  elementId is a global var in the js file.  

<input name="bla" type="text" id="bla" onchange="elementId=this.id;  someObject.method();" value="7.00" />

That being said I don't like this solution. I agree e.currentTarget would be the best approach e doesn't exist in the BB.  Am I missing something?

Hello

I would pass the id in the method parameter.

onchange="someObject.method(this.id)"

I'm not sure that the event.currentTarget.id would work for a text box, I don't think this method works in IE.

Tried that already.  Once in the method the reference to this is set to the current object and not the page.

I tried onchange="foo(event.currentTarget.id)" and that worked fine (note the lowercase 'e' in event).

Excellent.  I thought I had tried that already but I think I had the event reference in my external js file which would have flawed the test.

Thanks
