HTMLHelp Forums _ Client-side Scripting _ Which events are called?

Posted by: msucimaster Mar 21 2021, 04:13 PM

I want to show a picture when an entry in a select box an entry is selected. It should be shown immediately as it is meant as a help for people to choose the right option. So I need to know which events are generated that I can use.

The selected box has multiple rows (size=4).

Can someone help me with this information?

onchange for the SELECT. The value for SELECT is the value of the chosen option.

function getOption(x)

<select onchange="getOption(this.value);">
<option selected>Choose a Pet</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
<option value="parrot">Parrot</option>

Note that the returned value is that of the value attribute, not what's visible on the page. So if the first option is chosen 'dog' not 'Dog' will be returned.
