Encode a set of form elements as an array of names and values.

.serializeArray()🡢 Array

The .serializeArray() method creates a JavaScript array of objects, ready to be encoded as a JSON string. It operates on a jQuery collection of forms and/or form controls. The controls can be of several types:

  <div><input type="text" name="a" value="1" id="a" /></div>
  <div><input type="text" name="b" value="2" id="b" /></div>
  <div><input type="hidden" name="c" value="3" id="c" /></div>
    <textarea name="d" rows="8" cols="40">4</textarea>
    <select name="e">
      <option value="5" selected="selected">5</option>
      <option value="6">6</option>
      <option value="7">7</option>
    <input type="checkbox" name="f" value="8" id="f" />
    <input type="submit" name="g" value="Submit" id="g" />

The .serializeArray() method uses the standard W3C rules for successful controls to determine which elements it should include; in particular the element cannot be disabled and must contain a name attribute. No submit button value is serialized since the form was not submitted using a button. Data from file select elements is not serialized. Elements that do not contain a value attribute are represented with the empty string value.

This method can act on a jQuery object that has selected individual form controls, such as <input>, <textarea>, and <select>. However, it is typically easier to select the <form> element itself for serialization:

$("form").submit(function (event) {

This produces the following data structure (provided that the browser supports console.log):

    name: "a",
    value: "1",
    name: "b",
    value: "2",
    name: "c",
    value: "3",
    name: "d",
    value: "4",
    name: "e",
    value: "5",

Get the values from a form, iterate through them, and append them to a results display.

<p><b>Results:</b> <span id="results"></span></p>
  <select name="single">
  <select name="multiple" multiple="multiple">
    <option selected="selected">Multiple</option>
    <option selected="selected">Multiple3</option>
  <br />
  <input type="checkbox" name="check" value="check1" id="ch1" />
  <label for="ch1">check1</label>
  <label for="ch2">check2</label>
  <input type="radio" name="radio" value="radio1" checked="checked" id="r1" />
  <label for="r1">radio1</label>
  <input type="radio" name="radio" value="radio2" id="r2" />
  <label for="r2">radio2</label>
select {
  font-size: 14px;
form {
  margin: 5px;
p {
  color: red;
  margin: 5px;
b {
  color: blue;
function showValues() {
  var fields = $(":input").serializeArray();
  jQuery.each(fields, function (i, field) {
    $("#results").append(field.value + " ");

$(":checkbox, :radio").click(showValues);
