Jquery global array variable and dynamically created button issue

Question

I have global array variable so i can access it from many functions. Problem occurs when im trying to use this variable in function that is bind to button created dynamically, variable is undefined then.

var array = [[]];

  $('#edit').on("click", "input[id='button']", function(){

... i can't use this variable here and i wanna to put some values:- array[index1][index2]=...

});

I even made function to get this array and assign to new variable, and i can get values that was already in this array, but i can't add new ones cause of error "can't convert undefined to object". What seems to be the problem, and how to solve that ? Maybe some workaround ?

Thx,i know this, but i use a lot with "^=" so i went for longer version ;d — norbidrak

Are you sure your indexes are correct? On the initialization you are creating an empty array at array[0], so the first added value would be at array[1]. The inner brackets are not necessary for a multidimensional array, it's just var array = []; unless you wanted to initialize an empty array at index 0. Also when you're assigning the value, make sure the second dimension of the array is initialized:

var array = [[]];    // creates an empty array at index 0, so we'll add at 1
array[1][0] = 'foo'; // won't work since array is not initialized
array[1] = []; 
array[1][0] = 'bar'; // works

If that doesn't help try posting more code, like how your indexes are generated.

Yeah that helped. I still can't reach that global variable, but my workaround now works.You were right, problem was with initializing second dimension for higher index of array. Thanks.
