checking if a value changed in onblur event handler

[laredotornado]

Hi,

Using the onblur handler in a text field, how can I check if the value
was changed from what was originally there prior to the user focussing
on the text field?

Thanks, - Dave

Store the value in the onfocus handler and check against it in onblur.

Why you use the onblur,but not use onkeydown or onchange?

Because that isn't what the OP asked for. onkeydown doesn't enter
into it, but you could use onchange instead of onfocus and onblur.

when onchange event is invoked ?
is it invoked when the actual value of text field is
changed by user interaction (by key board/ mouse - copy paste)?
what if, the value of text field is changed by the script and not by I/
O device?

I am changing the value of text field by a java script
(asynchronous) and i want that event catched when value changed.
"onchange" does not work at that time.

Is there any way to detect the change?

No, but if it is your code that is doing it, why not do whatever you need to
do after setting the value.

Hello Dave
Actually my code is not changing the value, I am using a
third party javascript
Utility(html-editor: GPL ). Which changes the value. I can't change
the utility code(GPL).
Therefore I wanted to detect that change.

Thanks.

Unless the editor can do a callback on this change or can be
subclassed, I don't know what you can do.
