If use typed comma or semi-colon, or changes
focus to a different form element, test function will be called. And
below is my code:

<script language="Javascript">
function test(myObject, flag)
{
if ( (flag) || ((event.keyCode == 59) || (event.which == 59)) || ((event.keyCode == 44) || (event.which == 44)))
{alert(myObject.value);}
}
function closeWin()
{self.close();}
</script>
...
<form name='test'>
<textarea
name='textareaName' cols='44' rows='3' onChange='test(this, true);'
onKeyPress='test(this);' onBlur='test(this, true);'
></textarea>
<input type='text' name='textName'>
<input type='button' name='buttonName' onclick='closeWin();' value='Cancel'>
</form>
...

I
have a problem: when input value(e.g: test;) into textareaName field,
the test function is always run more one time. Please show me the way
can run this only one time.

Thanks in advance,

why don't you just use OnChange ?
the other events are conditionned by that one
it's normal you get multiple calls, as you've multiple events

Hi VGR

Thank for your reply.
But i'm still get stuck with this.
Actualy i want this function is called when user types comma or semi-colon, or changes value/focus to a different form element.
If just use onChange event how can it get this function when user types comma or semi-colon.
Please explain more detail for this.

Thanks in advance,

OnChange is triggered as soon as the value in the control changes, AFAIK

So typing ; , or whatever except TAB will trigger it, I think.
