HELP: Problem with Mozilla - Netscape and moving layers

G

GD

I'm using a script that works great on IE, but not on mozilla. the
original one worked also on N4, but i'd like it to be funcional with
mozilla.

this is the orginal script:

*****************************
<Head>
<script language="JavaScript1.2">
var menu1top=230
var menuleft=-115


var pace=14

var step
var direction
var pause=25

var thismenu
var vorzeichen=1
var vorzeimenu1=-1


var menuismoving="no"


function inite() {
if (document.layers) {
document.menu1.left=menuleft
document.menu1.top=menu1top

}
if (document.all) {
document.all.menu1.style.posLeft=menuleft
document.all.menu1.style.posTop=menu1top
}
}

function getmenuname(clickedmenu) {
if (menuismoving=="no") {
if (document.layers) {
thismenu=eval("document."+clickedmenu)
}
if (document.all) {
thismenu=eval("document.all."+clickedmenu+".style")
}
step=pace
checkdirection()
movemenu()
}
}

function checkdirection() {
if (document.layers) {
if
(thismenu==document.menu1){vorzeimenu1=vorzeimenu1*-1;vorzeichen=vorzeimenu1}
}
if (document.all) {
if
(thismenu==document.all.menu1.style){vorzeimenu1=vorzeimenu1*-1;vorzeichen=vorzeimenu1}
}
menuismoving="yes"
}

function movemenu() {
if (document.layers) {
if (step>=0) {
thismenu.left+=step*vorzeichen
step--
var movetimer=setTimeout("movemenu()",pause)
}
else {
menuismoving="no"
clearTimeout(movetimer)
}
}
if (document.all) {
if (step>=0) {
thismenu.posLeft+=step*vorzeichen
step--
var movetimer=setTimeout("movemenu()",pause)
}
else {
menuismoving="no"
clearTimeout(movetimer)
}
}
}


</script>

<style type="text/css">
#menu1 {position:absolute;left:-1000px;}
.baseline {
position:absolute;
left:250px;
top:20px;
font-family:Arial;

"Document.layers" is Netscape code up to version 4. Thereafter, it was
dropped and does not work.
}
if (document.all) {
document.all.menu1.style.posLeft=menuleft
document.all.menu1.style.posTop=menu1top
}
}
Click to expand...
"Document.all" is Microsoft code and does not work (except on those,
such as Opera, which can mimic Microsoft-code).

The net effect you have is that you do not use *any* W3C-standard code
and therefore your script will not work withe modern browsers. Switch to
using the "document.getElementById("id_ref") methods.

Thank you for your advise.

i've changed what you suggested, but somehow the last statement still
doesn't in Mozilla. in fact i got rid of most "if"and it works on IE,
but not Netscape.
Any idea why?

thanks,
GD

In place of *both* your "if" statements, you can use the following:-

if (document.getElementById()) {
document.getElementById(your_element_id).style...
etc.

This replaces all your "browser detection" with detecting the capability
of the browser rather than the manufacturer. Should it fail that test
(so, obviously, in an "else" clause) you can then run your browser
detection to deal with older browsers. There are more detailed examples
of this sort of thing in the group FAQ.

thismenu=eval("document.getElementById('clickedmenu').style")

Terrible script, with all that eval()ing...the above bit should
illustrate why. You're passing the string 'clickedmenu' to the
function, not the string contained in the variable clickedmenu.

thismenu=document.getElementById('clickedmenu').style

And:

thismenu=document.all[clickedmenu].style

There are so many menu scripts floating around these days, of every
variety, there's no reason to waste any time modifying relics of this
sort.

Thanks for your answer and the link, it's a great resource for scripts
and to learn DHTML.

somebody sent me the following script that works great. i'm unable to
add more than one tab though (i'm in the process of learning JS thru
other peoples scripts and website tutorials). what i like about it is
the use of image maps instead of styles for the menus for design
purposes. any help will be greatly appreciatted.

thanks, GD
