Jquery - get the name of an array item in an array

Question

How do you reference the name of an array within an array?

var jon_count = [0,6,7,9]
var sue_count = [9,7,6,8]
var rob_count = [7,8,6,3]
var name_list = {jon_count, sue_count, rob_count}

I'm trying to get the name of each variable within the "name_list" not the values of each item.

$.each(name_list, function (index, value) {
    $.each(value, function(ind, obj) {
       console.log(value[ind]);
    });
});

I know that's garbage, I want to see:

jon_count
sue_count
rob_count

But I keep getting the numbers.

You can just use the index variable:

$.each(name_list, function (index, value) {
  alert(index);
});

Here is a fiddle.

Thanks Steve. This worked. Is there a way to use this information to dynamically reference this, let's say in a loop like where I only have the first name tmname = index.toLowerCase(); window[tmname + "_count"][0] the problem here is that I'm getting an error on the index of the 0.

Oh, I found it. I have to reference the the first array and index that within the index (if that make sense) - I used: name_list[ thename ][0].

i think you need this:

var name_list = {jon_count:"item 1", sue_count:"item 2", rob_count:"item 3"} 
var keys = Object.keys(name_list)
keys.forEach((item) => {
  console.log(item)
})
