Guy Watson:
Array.prototype.in_array=function(value){
for(var z=0;z<this.length;++z){
if(this[z] == value){
return true
}
}
return false
}
Also found this @ layer51.com/proto:
msg3 { *k-zimir* [+] <http://www.layer51.com/proto/up.aspx?u=k-zimir>,
posted: 10.22.02 9a•-, top [^]
<http://www.layer51.com/proto/d.aspx?f=6#> } except using a while
loop, this returns the position if found and -1 if
not.. might be little handsomer sometimes.
Array.prototype.in_array=function(value){
var l;
l = this.length;
while(l--)
{
if(this[l] == value){
return l;
}
}
return -1;
}
Of course you could rewrite the above to make them AS2. There are tons of
Array prototypes to be found there. (www.layer51.com/proto)
