Use of indexOf() Method in JavaScript

Question

var araj=["1","2"];  
var idx=Array.IndexOf(araj,"1");

Doesn't work as expected. Why, and what's next?

EDIT: it is javascript in asp.net (so the friend who won't open account here says)

And what results are you getting? – GendoIkari Nov 04 '10 at 18:03 — GendoIkari, Nov 04 '10 at 18:03
What language is this? C#? VB? JavaScript? – Matt Ball Nov 04 '10 at 18:03 — Matt Ball, Nov 04 '10 at 18:03
have you tried `araj.IndexOf("1");` ? – Pekka Nov 04 '10 at 18:03 — Pekka, Nov 04 '10 at 18:03
Why is this ASP now? It was Javascript a second ago – Pekka Nov 04 '10 at 18:05 — Pekka, Nov 04 '10 at 18:05
Guys, sorry, it's jscript in asp.net – Daniel Mošmondor Nov 04 '10 at 18:10 — Daniel Mošmondor, Nov 04 '10 at 18:10

Change IndexOf to indexOf.

Javascript is case-sensitive.

Javascript is case sensitive language. IndexOf should be indexOf:

var araj=["1","2"];  
var idx=Array.indexOf(araj,"1");

Result:

Although equivalent, I prefer this method.

var araj = ['1', '2'];
var idx = araj.indexOf('1');
alert(idx);
