#16170 — dear DOM

HTML code:
<input type="text" id="field1">

<select id="mySel">
</select>

js code: function X
... that would populate the mySel element based on the value/input of
field1

Question, how could we trigger the js function X right upon data/value
input of field1 without manually clicking on event trigger/handler?  I
know I don't know enough of DOM...
Ideally achieve it without resorting to HTML5.

Thanks.

I don't see how that can be possible.
How can your script know when I am done typing?
Suppose I am typing in your "field1" the following:
justaguy

How then can your script know when I am done typing?
If you use an event like KeyUp you will fill your select with:
j
ju
jus
just
etc.

So what is it you want to program?

"resorting"?

One /might/ use the change event of the input element.  This occurs as
soon as the input looses focus, if any changes were made.

I haven't thought of this event handler at the first field.  You're a
genius.  Thank you.
