Form element array encryption.

Description

The .serializeArray() Ajax method, allows us to encode a set of form elements as an array of name/value pairs ready for encoding as a JSON string.

  • The .serializeArray() method returns an array of objects ready to be encoded as a JSON string and operates on a jQuery object representing a set of form elements.
  • The .serializeArray() method can act on a jQuery object that has form elements of several types if required, although it is generally easier to select the <form> element.
  • Only 'successful controls' are serialized to the returned string as outlined in the  W3C Proposals.

.serializeArray() ExampleTop

Encode a set of form elements as an array of name/value pairs ready for encoding as a JSON string.

In the example below when we press the 'Submit' button we serialize the 'successful controls' from the form below into an array of name/value pairs. For the example we output a message but the resultant array could just as easily be encoded into a JSON string. Change some values in the form and press the 'Submit' button to see the varying results.


$(function(){
  $('#form2').submit(function() {
    $('#div2').append(JSON.stringify($(this).serializeArray()) + '<br>');
    return false;
  });
;});
