How do I incrementally build and tear down a JavaScript object?

I need a user to be able to perform these actions:

1. Click an "Add" button. This will add a JavaScript object to either an array, or another JavaScript object.
2. Click a dynamic "Remove" button. This will remove the JavaScript object from the array, or object, whose ID matches the button click.
3. Submit the complete array, or object, of desired objects server-side for processing.

Using an array, am I able to get a handle via ID on a specific element and remove it with a "pop"-like functi开发者_开发技巧on? If not, am I able to do so using a JavaScript object?

This question is related to this post, but there isn't much context in the original to answer my question. Thanks!

You can append an element to an array using the push method, like this:

var someArray = [];    //Start with an empty array

//Later,
someArray.push({ name: 'value' });

It may actually be better to use an object rather than an array. This will allow you to name each object you send back to the server.

var dataObject = {};

function addData(name, data1, data2, data3) {
    dataObject[name] = {
        data1: data1,
        data2: data2,
        data3: data3        
    };
}

function removeData(name) {
    delete dataObject[name];
}
