I'm trying to get some javascript working, unfortunately I didn't write it - and the person who did is on holiday!

This seems to work on some machines and not others (even with the same version of ie, 6).

I think the problem is something to do with the eval function, but i'm not sure what to use instead.

any help would be greatly appreciated

thanks

Emma


manu=navigator.appName;
vers=navigator.appVersion;
ie3=0;
window.searchmap.debug.value = document.images;
if (manu.indexOf("Microsoft")>=0 && vers.indexOf("3")>=0) ie3=1;

if (document.images && ie3==0 ) {
var ukon = new Image();
ukon.src = "/home/images/newnav/btn-ukprop-active.gif";
var ukoff = new Image();
ukoff.src = "/home/images/newnav/btn-ukprop.gif";
var euroon = new Image();
euroon.src = "/home/images/newnav/btn-europrop-active.gif";
var eurooff = new Image();
eurooff.src = "/home/images/newnav/btn-europrop.gif";
var agentson = new Image();
agentson.src = "/home/images/newnav/btn-agents-active.gif";
var agentsoff = new Image();
agentsoff.src = "/home/images/newnav/btn-agents.gif";
var contacton = new Image();
contacton.src = "/home/images/newnav/btn-contact-active.gif";
var contactoff = new Image();
contactoff.src = "/home/images/newnav/btn-contact.gif";
var companyon = new Image();
companyon.src = "/home/images/newnav/btn-companyinfo-active.gif";
var companyoff = new Image();
companyoff.src = "/home/images/newnav/btn-companyinfo.gif";

}


function imgOn(imgName) {
if (document.images) {
window.searchmap.debug.value = eval(imgName + "on.src");
document
.src = eval(imgName + "on.src");
}
return true;
}

function imgOff(imgName) {
if (document.images) {
window.searchmap.debug.value = eval(imgName + "off.src");
document
.src = eval(imgName + "off.src");
}

return true;
}

what the error message ?

maybe change this :
document
.src = eval(imgName + "on.src");
TO :
eval("document." + imgName + ".src") = eval(imgName + "on.src"); ---------------------------------------

yes, all the images are defined. forgot show how i was calling it:
<A class=&quot;navbar&quot; href=&quot;/index.asp?&quot;><IMG src=&quot;/home/images/newnav/btn-europrop.gif&quot; border=&quot;0&quot; name=&quot;euro&quot; onMouseOver=&quot;window.status=''; return imgOn('euro');&quot; onMouseOut=&quot;window.status=''; return imgOff('euro');&quot;></A>

I've got to go home now, and i'm not at work till monday. So thanks for all your help - and i'll probably be pestering you then!

still doesn't work

so it now reads:

<A class=&quot;navbar&quot; href=&quot;/index.asp?&quot;><IMG src=&quot;/home/images/newnav/btn-europrop.gif&quot; border=&quot;0&quot; name=&quot;euro&quot; onMouseOver=&quot;window.status=''; imgOn('euro');&quot; onMouseOut=&quot;window.status=''; imgOff('euro');&quot;></A>
