Here are some useful Javascript snips for working with form data.

How to get the name of the HTML tag for an element:


This code will see if we have a map set of inputs (somename[]):

// See if we have a map here
var mapFound = 0;
if (thisName.indexOf('[]') != -1) {
    mapFound = 1;
    thisName = thisName.replace(/[\[\]']+/g, '');

How to take a map of inputs and turn them into a Javascript map type var, and toss the empty ones:

var map = $(thisName).map(function(){
    if (this.value != '') {
        return this.value;
    } else {
        return null;
