Problem with accessing/ defining multi level array variable

[leruman]

Greeting to eveyone.

 

I am following this board for some time, have learned lot of good things. I am beginer in PHP/ java scrip. Code listed belov is part of larger file, i have included relevant files for this problem. I want to define multi level array in jscript file, and to be able to acces it from all functions. From my beginer level of knowldge this code and function shold work and allow this function to set value to variable attacks. Unfortunaltely it throws error:

Uncaught TypeError: Cannot set property '0' of undefined

like array is not deffiend at all. Can someone experienced tell me where i have made mistake and how to define muliti level array whch can be accesed from existing functions in file.

 

Thanks in advance.

 

var attack = new Array(new Array);
$(document).ready(function(){

	$('.seltarget').change(function() { 
                // settig value data           
                var player= $(this).nextAll('#player').val();
                var pattack = $(this).nextAll('#pattack').val();
                var target = $(this).val();
                var party = $("#party").val();
                
                $(this).next().val($(this).children('option:selected').text());
                
			$.post('settarget.php',{
			'player':player,'pattack':pattack,
			'target':target,
			'party':party
			});
                
                attack[player][pattack]=target;
        });

});
