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.
