function call?

Hi. Question. Say I have <a onclick=' return Outline(this)' onmouseover=' return Outline(this)'>. How could I determine in Outline() that it was launched from a mouseover, as opposed to onclick?

function Outline(oElement, oEvent) {
var sType = oEvent && oEvent.type || "unknown";
alert(sType);
}
....
<a ...
onclick="return Outline(this, event)"
onmouseover="return Outline(this, event)"[color=blue]

onclick="return Outline(this, 'onclick')"
onmouseover="return Outline(this, 'onmouseover')"

That's no improvement at all.

I think it is. Simplicity usually wins.

Right, and passing the event with all event handlers is simpler than
hard-coding a different string with every mouseover, click and whathaveyou,
wouldn't you think?

It's not "simple" to write down a string that's already present
as a property of the event object, nor is it "simple" to write
different code for different event handlers where a versatile
variant can be just copied&pasted.

Beyond that you make it harder to maintain: if I have a typo
like "return Outline(this, ebent)", I will most likely get an
error or exeption in this very line, e.g. telling me that there
is no such property. If you have a typo like "return Outline(
this, 'onclock')", you'll most likely get unexpected behaviour
in the function Outline(), thus not in the typo's place.

re: function call?

How about something like:
<script>
function myfun(good,stuff){
if (stuff.type=="click") theevent="click event"
if (stuff.type=="mouseover") theevent="mouse over event"
alert(theevent)
}
</script>

<a id="fred" href="urlhere" onclick="myfun(this,event)"
onmouseover="myfun(this,event)" >Object stuff</a>

re: function call?

I was hoping for a way that didn't involve passing another parameter, but it'll work...Dennis
