javascript wtf

[grifter7]

var $pixel=2;
function $space(){
spool=setInterval("$time()", 100);
}

function $time(){
$pixel+=2;
document.getElementById("move").style.marginLeft=$pixel+"px";
clearInterval(spool);
if($pixel==70){
clearInterval(spool);
}}

um i cant get this to work but im really confused by the fact that when i scroll my mouse over the link very fast multiple times it seems to break and just keep going does anyone know why?

What events are you using to detect mouseover?

And why do you clear the interval, then clear it again (which will error, since you've already killed it) conditionally?

clearInterval(spool);
if($pixel==70){
clearInterval(spool);

i realise i stopped it twice but i was still confused. The

if($pixel==70){clearInterval(spool);

part on its own doesnt stop the menu bar it just keeps rolling to the right. I used

onmouseover

to call

function $space(){

I cant seem to cancel the loop without it either instantly moving seventy pixels to the left or causing my browser to crash.

Just a note: as far as I know, javascript functions and variables can contain only alphanumeric characters (alphabet and digits) and the underscore. Also, the name cannot begin with a numeral. I would have avoid using $ within the name of functions and variables. After all it is javascript, not php

thanks ill use _ from now on then

The dollar sign is actually a perfectly valid character, and it can be used anywhere in a variable name. We might choose to not use it for stylistic reasons, but there is no practical reason to avoid it.

Indeed, otherwise JQuery wouldn't work. I agree, though, stylistically it should be avoided in JS.
