Serialize is more convenient when you just want to perform an HTTP request (just put the result in the query string), whereas serializeArray is more convenient if you want to process the results yourself.
The.serialize() method generates a text string in URL-encoded format. It may be used on a jQuery object that has individual form controls selected, such as input>, textarea>, and select>: $("input, textarea, select")$("input, textarea, select")$("input, textarea, select")$("input, textarea, select
By serialising form values, the serializeArray() method creates an array of objects (name and value). You can choose one or more form elements (such as input and/or text area) or the entire form element.
Use the serializeArray() function to receive a value from a serialised array. All forms and form elements, such as the, are serialised using the serializeArray() method. However, instead of returning a JSON data structure, the serialise() method produces a JSON data structure for you to deal with.
