Question

I am trying to add values to a simple array, but I can’t get the values pushed into the array.

So far so good, this is the code I have:

codeList = [];

jQuery('a').live(
    'click', 
    function()
    {
         var code = jQuery(this).attr('id');
         if( !jQuery.inArray( code, codeList ) ) {
              codeList.push( code );
              // some specific operation in the application
         }   
    }
);

The above code doesn’t work!
But if I manually pass the value:

codeList = [];

jQuery('a').live(
    'click', 
    function()
    {
         var code = '123456-001'; // CHANGES HERE
         if( !jQuery.inArray( code, codeList ) ) {
              codeList.push( code );
              // some specific operation in the application
         }   
    }
);

It works!

I can’t figure out what’s going on here, because if I do other tests manually it also work!

Try this .. Instead of cheking for bool check for its index..
It returns a -1 when it is not found..

var codeList = [];

jQuery('a').live(
    'click', 
    function()
    {
         var code = '123456-001'; // CHANGES HERE
         if( jQuery.inArray( code, codeList ) < 0) { // -ve Index means not in Array
              codeList.push( code );
              // some specific operation in the application
         }   
    }
);
