Passing String As An Array

[snakehips2000]

I've got problems with the following JavaScript code. Although the array is seemingly created, I'm unable to access the individual elements (in this case, the first one 'uno'). Instead the browser displays the whole array, i.e. 'uno', 'dos', 'tres'. When I replace "document.writeln(arr2[0]);" with "document.writeln(arr2[1]);" I receive "undefined":

<script language = "Javascript">

function DuplicateRows(arry) {
var str=arry.substring(1, arry.length-1);
var arr2=new Array(str.split(","));
document.writeln(arr2[0]);
}

DuplicateRows("~'uno', 'dos', 'tres'~");
</script>

Any help much appreciated.

Hi

[tt]String.split()[/tt] returns an [tt]Array[/tt]. There is no need to call [tt]Array[/tt]'s constructor yourself.

var arr2=str.split(",");
