This sample serializes an object to JSON. Serialize an Object. Serialize a Collection. Serialize a Dictionary. Serialize JSON to a file. Serialize with. Form serialize javascript (no framework). Dependencies that can convert the HTML form into a JSON like object which is. Form to the result from jQuery's. The query string is in identical form to the result from jQuery's $.serialize method. +1 for taking the time to improve the code. I enjoy when people find my flaws, since it is a good learning opportunity. +1 for keeping it looking nice as well.

Wondering is there a function in javascript without jquery or any framework that allows me to serialize the form and access the serialized version?

JQuery Serialize Object. As seen on StackOverflow: Convert forms to JSON LIKE A BOSS. Adds the method serializeObject to jQuery, to perform complex form serialization into JavaScript objects. The current implementation relies in jQuery.serializeArray to grab the form attributes and then create the object using the input name attributes. If the DOM you have is an HTML document, you can serialize using serializeToString, but there is a simpler option: just use the Element.innerHTML property (if you want just the descendants of the specified node) or the Element.outerHTML property if you want the node and all its descendants.

The miniature from-serialize library doesn't rely on a framework. Other than something like that, you'll need to implement the serialization function yourself. (though at a weight of 1.2 kilobytes, why not use it?)

Here is pure JavaScript approach:

Though it seems to be working only for POST requests.

For modern browsers only

If you target browsers that support the URLSearchParams API (most recent browsers) and FormData(formElement) constructor (most recent browsersexcept Edge), use this:

Everywhere except IE

For browsers that support URLSearchParams but not the FormData(formElement) constructor, use this FormData polyfill and this code (works everywhere except IE):

Example

Compatible with IE 10

For even older browsers (e.g. IE 10), use the FormData polyfill, an Array.from polyfill if necessary and this code:

Here's a slightly modified version of TibTibs':

Disabled fields are discarded and names are also URL encoded. Regex replace of %20 characters takes place only once, before returning the string.

The query string is in identical form to the result from jQuery's $.serialize() method.

I started with the answer from Johndave Decano.

This should fix a few of the issues mentioned in replies to his function.

  1. Replace %20 with a + symbol.
  2. Submit/Button types will only be submitted if they were clicked tosubmit the form.
  3. Reset buttons will be ignored.
  4. The code seemed redundant to me since it is doing essentially thesame thing regardless of the field types. Not to mentionincompatibility with HTML5 field types such as 'tel' and 'email',thus I removed most of the specifics with the switch statements.

Button types will still be ignored if they don't have a name value.

This is how I am currently using this function.

If you need to submit form 'myForm' using POST in json format you can do:

The second line converts from an array like:

..into a regular object, like:

..it does this conversion by passing in a mapFn into Array.from(). This mapFn is applied to each ['a','b'] pair and converts them into {'a': 'b'} so that the array contains a lot of object with only one property in each. The mapFn is using 'destructuring' to get names of the first and second parts of the pair, and it is also using an ES6 'ComputedPropertyName' to set the property name in the object returned by the mapFn (this is why is says '[x]: something' rather than just 'x: something'.

All of these single property objects are then passed into arguments of the Object.assign() function which merges all the single property objects into a single object that has all properties.

Array.from():https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/from

Destructuring in parameters:https://simonsmith.io/destructuring-objects-as-function-parameters-in-es6/

If you are looking to serialize the inputs on an event. Here's a pure JavaScript approach I use.

Data will be a JavaScript object of the inputs.

A refactored version of @SimonSteinberger's code using less variables and taking advantage of the speed of forEach loops (which are a bit faster than fors)

Stefan GabosStefan Gabos
Eduardo BorgesEduardo Borges

I refactored TibTibs answer into something that's much clearer to read. It is a bit longer because of the 80 character width and a few comments.

Additionally, it ignores blank field names and blank values.

I've grabbed the entries() method of formData from @moison answer and from MDN it's said that :

The FormData.entries() method returns an iterator allowing to go through all key/value pairs contained in this object. The key of each pair is a USVString object; the value either a USVString, or a Blob.

but the only issue is that mobile browser (android and safari are not supported ) and IE and Safari desktop too

but basically here is my approach :

Say I have something like:

I want to serialize that object. I tried:

Any ideas?

You should use jQuery.param() instead.

Working Example

With vanilla JS, you would use JSON.stringify instead.

As mentioned you should use .param()

But also you need to be careful with your syntax. Your brackets don't match, and that color will need quotation marks. jsFiddle

You could use JSON.stringify to serialize your object, and you'd have to wrap your color string correctly:
