Question

I have a drop down list on my form.

What is the event I would use in javascript that triggers once the user has made a selection on a drop down. I tried on change but that did on work.

    DROP DOWN

Answer 1

onchange is the correct event.

HTML

<select onchange="SelectChanged(this)">
...
</select>

JS

function SelectChanged(obj) {
    ...
}

Here’s a very simple working example to get you going.
