javascript add element to serialized form array

How to Add Element to Serialized Form Array in JavaScript#

Adding an element to a serialized form array in JavaScript can be done through several methods. Here are some ways:

Method 1: Using the push() Method#

The push() method is used to add one or more elements to the end of an array, and it returns the new length of the array.

let serializedArray = $('form').serializeArray(); // getting serialized array
serializedArray.push({name: 'newFieldName', value: 'newFieldValue'}); // adding new element

Method 2: Using the concat() Method#

The concat() method is used to merge two or more arrays, and it returns a new array that contains all the elements of the merged arrays.

let serializedArray = $('form').serializeArray(); // getting serialized array
let newElement = [{name: 'newFieldName', value: 'newFieldValue'}]; // creating new element
serializedArray = serializedArray.concat(newElement); // adding new element

Method 3: Using the serialize() Method#

The serialize() method is used to create a URL-encoded text string by serializing form values. You can add a new field to the form and then serialize it to get the updated serialized array.

let newForm = $('form').append('<input type="hidden" name="newFieldName" value="newFieldValue">'); // adding new field to form
let serializedArray = newForm.serializeArray(); // serializing form to get updated serialized array

These are some of the ways to add an element to a serialized form array in JavaScript.
