JS Check Jquery inArray

Question

I would like to use a onchange state on a select element to check if the value of the select is in an array.

I tried this :

function statutEmployeur(){
   statliste = [];
   statliste.push(1);
   statliste.push(2);
   statliste.push(5);
   statid = jQuery("#statut").val();
   if(jQuery.inArray(statid,statliste)>-1){
      alert('inside array');
   }else {
      alert('outside array');
   }
}

Each value that I tried are outside of the array. Anybody can help me ?

Thanks

hey there i'd love to help you, mind throwing your current code (html,js) up into jsbin? makes it easier to give you specific advice. — tdc

Is this possibly a type issue? "1" is not considered to be in an array of [1, 2, 5] — Stryner

as pointed out by Stryner in the comments, try running your .val() through parseInt() to ensure you nave a numerical value (and not a string)

   statid = jQuery("#statut").val();

to:

   statid = parseInt(jQuery("#statut").val(), 10);

the problem is you're searching in the array for a type of string (default type of inputs), but your array only contains numbers. You could either make your array into numbers, or do a type conversion like above to ensure you're working with the same type.
