function as parameter of a jscript function - how?

[José Joye]

Hello,

I'm having problem with my onLoad event of the <a> tag.
In fact, I want to pass as second parameter of my jscript function another
jscript function.
I could not manage to find the correct syntax.

Any hints welcome

José


here is my snippet:

<a href="../Newsletter.htm"
onMouseOver="F_roll('NavButton3',1)"
onMouseOut="F_roll('NavButton3',0)">
<ILAYER ID="NavButton3"></ILAYER>
<img ID="NavButton3" name="NavButton3" height="24" width="100"
src="javascript:F_getImageName('../images/Newsletter',0)"
onLoad="F_loadRollover(this,F_getImageName('./images/Newsletter',1),0)"
border="0" alt="Letter1">
</a>

I might be wrong but I don't believe you can use an onload event in an <a> tag because it's
basically a "window" event and needs to be either in the body tag or at the bottom javascript
section as onload="function()"


To make a function run another function nest them and the functions and onload would look like this

<script type="javascript">
function1(){
function info here
function2(){
function info here
}}
onload="function1()"
</script>

However if you want it to be a user initiated event tied to the <a> tag it would be an onclick event
like this:

<a onclick="function1()">

and then

<script type="javascript">
function1(){
function info here
function2(){
function info here
}}
</script>

Thanks,

You're right, the onload is not part of my <A> tag but of my <img> tag

Hello,

This seems to be a standart function I have taken from the web.

I turned aroud the problem wrapping it inside another function that will get
the string first and then call it

Thanks,
José

function F_loadRollover(image,imageName,menu) {
if (image && image.src &&
(null == image.out || typeof(image.out) == typeof(void(0)))) {
s = image.src;
image.out = new Image();
image.out.src = s;
image.over = new Image();
if (imageName.lastIndexOf('/') >= 0 || imageName.lastIndexOf('\\') >= 0) {
s = imageName;
} else {
i = s.lastIndexOf('/');
if (i<0) i = s.lastIndexOf('\\');
if (i<0) { s = imageName; }
else { s = s.substring(0,i+1) + imageName; }
}
image.over.src = s;
image.menu = menu;
loaded[image.name] = image;
}
}
