Hi All,
I have a page with three textboxes. Call them txt1, txt2, and txt3.
Using javascript I need to populate txt3 with whatever has been typed
into txt1 and txt2 as the information is being entered. No problem
there, but I want to update txt3 whenever the user uses the delete or
backspace key in either txt1 or txt2. I capture the delete or
backspace keystrokes, but when I try to update txt3 it is always a
step behind. That is at the time of the keystrokes the value of txt1
or txt2 has no yet been updated.
Does anyone have any suggestions for how to accomplish this?
TIA,
Sven

Look at http://www.mozilla.org/docs/dom/domr...ef.html#998961
and http://msdn.microsoft.com/library/de...nce/events.asp
and check the onkeypress event. You can access every keystroke.

Why to use keys values (that are not same ie on PC & Mac)
when JS has KeyUp & KeyDown ?
<input type=text name=text1
onkeyup="text3. value=this.valu e+text2.value;" >
<input type=text name=text2
onKeyUp="text3. value=text1.val ue+this.value;" >
<input type=text name=text3
onKeyDown="truc =this.value;" onKeyUp="this.v alue=truc;"> This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
