There's a function that does exactly this:

serialize() is not a good idea if you want to send a form with post method. For example if you want to pass a file via ajax its not gonna work.

Suppose that we have a form with this id : 'myform'.

the better solution is to make a FormData and send it:

In general use serialize() on the form element.

Please be mindful that multiple <select> options are serialized under the same key, e.g.

will result in a query string that includes multiple occurences of the same query parameter:

which may not be what you want in the backend.

I use this JS code to reduce multiple parameters to a comma-separated single key (shamelessly copied from a commenter's response in a thread over at John Resig's place):

which turns the above into:

In your JS code you'd call it like this:

Hope that helps.

Use

A good jQuery option to do this is through FormData. This method is also suited when sending files through a form!

Your send function in jQuery would look like this:

to add data to your form you can either use a hidden input in your form, or you add it on the fly:

You just have to post the data. and Using jquery ajax function set parameters. Here is an example.

serialize form fields to submit a form over ajax

install

use

form-serialize supports two output formats, url encoded (default) or hash (js objects).

Lets serialize the following html form:

api

serialize(form [, options])

Returns a serialized form of a HTMLForm element. Output is determined by the serializer used. Default serializer is url-encoded.

arg	type	desc
form	HTMLForm	must be an HTMLForm element
options	Object	optional options object

options

option	type	default	desc
hash	boolean	false	if true, the hash serializer will be used for serializer option
serializer	function	url-encoding	override the default serializer (hash or url-encoding)
disabled	boolean	false	if true, disabled fields will also be serialized
empty	boolean	false	if true, empty fields will also be serialized

custom serializer

Serializers take 3 arguments: result, key, value and should return a newly updated result.

See the example serializers in the index.js source file.

notes

New sinhala mp3 song download. only successful control form fields are serialized (with the exception of disabled fields if disabled option is set)

multiselect fields with more than one value will result in an array of values in the hash output mode using the default hash serializer

Vue Js Serialize Form

explicit array fields

Fields who's name ends with [] are always serialized as an array field in hash output mode using the default hash serializer.The field name also gets the brackets removed from its name.

This does not affect url-encoding mode output in any way.

indexed arrays

Adding numbers between brackets for the array notation above will result in a hash serialization with explicit ordering based on the index number regardless of element ordering.

Like the 'explicit array fields' this does not affect url-encoding mode output in any way.

nested objects

Similar to the indexed array notation, attribute names can be added by inserting a string value between brackets. The notation can be used to create deep objects and mixed with the array notation.

Like the 'explicit array fields' this does not affect url-encoding mode output.
