Usage no npm install needed!

<script type="module">
  import aggulJquerySerializeobject from 'https://cdn.skypack.dev/@aggul/jquery.serializeobject';


Build Status

What is it?

$.serializeObject is a variant of existing $.serialize method which, instead of encoding form elements to string, converts form elements to a valid JSON object which can be used in your JavaScript application.


Whilst it isn't necessary in most cases, and by that I mean 99.99% kind of most, there are times when we manipulate form data on client side. Personally I find JSON much easier to work with than DOM or string manipulation.

How do I use it?

If you want to see the code and demo first: http://jsfiddle.net/davidhong/PRpJT/

Simply include the jQuery.serializeObject.js along with any jQuery instance and use it like $.serialize.

If you have a form like the following:

<form id="minutes">
    <input type="text" name="subject">
    <input type="text" name="minute-taker">
    <!-- ... -->
    <input type="checkbox" name="attendees" value="David" checked="checked">
    <input type="checkbox" name="attendees" value="Daniel" checked="checked">
    <input type="checkbox" name="attendees" value="Darwin" checked="checked">

and wish to convert them to a JSON object:

var minutes = $('form#minutes').serializeObject();

will return:

    "subject": "",
    "minute-taker": "",
    "attendees": [
