I have an asp.net program in which I place a marker on a google map when the address in a textbox is changed. This Javascript is triggered by the onchange event. However I have noticed that if the user does not 'tab' out of the box before clicking submit, the event does not fire. Is there a way I can fix this?

i want it to fire when the text is changed, it works correctly in most cases, the problem is when the user changes the text and immediately clicks the submit button without clicking out of the box first...it seems to skip firing the event.SHeinema– SHeinema2012-01-30 00:37:38 +00:00Commented Jan 30, 2012 at 0:37

Perhaps try onblur , occasionally I've had success with one when the other fails.mikey– mikey2012-01-30 00:41:09 +00:00Commented Jan 30, 2012 at 0:41

I think what you are trying to achieve is impossible. the onchange event, happens only when you lose focus on the element. You could use onkeypress, onkeydown or onkeyup to get that change quicker. The problem here is that the value of the textbox is going to be changed by the click of an external element and therefore, you cannot bind it directly to the textbox.
If you know exactly what the clickable elements would be, you could add a click event to each one of them, pointing to a function that would test the textbox current value against the latest known value and if they were different, do whatever you want to do. But i don't think that's the case...
following your comment, you should add a submit event to the form, that would compare the current state of the textbox before submitting the form...

Actually.......I do know the clickable elemets, really just the submit button, so I added a call to another function that check to make sure a field was set, if not it called the onchange fnc from there. Thanks ( :
