Javascript / jQuery Populating Multidimensional Arrays... Array with array elements

Question

I'm trying to populate a multidimensional array (array with array elements) via Javascript or jQuery... push() is probably the wrong method to use, but I've tried a couple of others and I can't seem to get beyond single dimensional arrays. Here's the latest try so far - any advice or snippets on how I might be able to populate arrays per element of an existing global array appreciated!


<script>
var fred=[];
for(i=0;i<3;i++){
    fred.push(['a',i]);
    $("#disp").html(i);
}
alert(fred.toSource());
$("#disp").html(fred.toSource());
</script>

<div id="disp">abc</div>

Can you explain a bit more what you're after? It's very abstract and hard to understand what the goal is at the moment...if you gave an example of what you expect the result to be it could be very helpful. — Nick Craver

i'd like to be able to assign multiple elements to each index of a main array - similar to what i'd do in php, but in javascript... this way, i can later loop through each "row" to display each array's "columns" — ina

Array.push should work fine. After all, a two-dimensional array is just an array of arrays.

The link you provided does pop up a message with a two-dimensional array. What's the problem?

fred is an array of arrays: [['a', 0], ['a', 1], ['a', 2]]. Maybe you're trying to use the number as a position? Then construct a separate "row" array, fill it up using row.push('abc') and then fred.push(row) for each row.

ahh! sorry my original error had to do with jQuery.inArray not being able to process multidimensional arrays... i had thought it was because my array was not populating.
