Question

All examples of adding new elements to associative arrays are going the “easy” way and just have a one dimensional array – my problem of understanding is having arrays within arrays (or is it objects in arrays?).

I have the following array:

var test = [
            {
                value: "FirstVal",
                label: "My Label 1"
            },
            {
                value: "SecondVal",
                label: "My Label 2"
            }
           ];

Two questions: How to generate this array of associative arrays (yes… object) from scratch? How to add a new element to an existing array?

Thanks for helping me understand javascript.

I’m not exactly sure what you mean by “from scratch”, but this would work:

var test = [];  // new array

test.push({
                value: "FirstVal",
                label: "My Label 1"
            });  // add a new object

test.push({
                value: "SecondVal",
                label: "My Label 2"
            });  // add a new object

Though the syntax you posted is a perfectly valid way of creating it “from scratch”.

And adding a new element would work the same way test.push({..something...});.
