Normal string functions in JavaScript?

[Seymour Clufley]

In PureBasic there's a function StringField for extracting items from a string split by a given delimiter. So:

list="apples|oranges|pears|melons|"
result=StringField(list,3,"|")

would return "pears".

How would you do that in JavaScript?

The end goal is to turn "http://images/im67547.jpg" into "im67547".

<script type="text/javascript">
var url='http://images/im67547.jpg'; // Test string here
alert(url.split('/')[3]); // resultant string
</script>

Just add it to the language; using 0-based indexing of course:<script type='text/javascript'>

String.prototype.getField=function(index, delim)
{
return this.split( delim )[ index ] || "";
}

list="apples|oranges|pears|melons|"

alert( list.getField(2, '|') );

</script>
