[TurboSRT4]

can someone please give me a simple example of creating a javascript list then checkin it for a value? I am fairly good with perl and heres is a perl example of what i need in javascript.

@list = ("one", "two", "three", "four");

foreach(@list){
if ($_ eq "one"){
$exist = "$_ exists in list";
}
}

thank you!

No Lists in JS,only Arrays.

Assuming its an array:

var myList=["one", "two", "three", "four"];
var x;
for(x in myList){
 if(myList[x]=='one'){
var exist='Exists in List';
 }

}
alert(exist);

Hi

Or abit different approach :

[b]var[/b] myList[teal]=[[/teal][green][i]"one"[/i][/green][teal],[/teal] [green][i]"two"[/i][/green][teal],[/teal] [green][i]"three"[/i][/green][teal],[/teal] [green][i]"four"[/i][/green][teal]];[/teal]
[b]if[/b] [teal]([/teal]myList[teal].[/teal][COLOR=darkgoldenrod]indexOf[/color][teal]([/teal][green][i]'one'[/i][/green][teal])!=-[/teal][purple]1[/purple][teal])[/teal] exist[teal]=[/teal][green][i]'Exists in List'[/i][/green][teal];[/teal]

We recently discussed about [tt]Array.indexOf()[/tt] in thread216-1593118 ( see comments starting at 3 Mar 10 9:24 ).
