jQuery.param( object ) Examplego to top of page Top

Create a serialized representation of an array or object, suitable for use in a URL query string or Ajax request.

In the example below when we press the button the first time we create a serialized representation of an object. For the example we output messages for this and also for the object decoded. The resultant string could just as easily be sent to a server as part of an Ajax request.


$(function(){
  $('#btn1').one('click', function(){
    var obj1 = {species: 'penguin', skills: {flight: 'no', swim: 'yes'}, climate: 'cold'};
    $('#div3').append($.param(obj1) + '<br />');
    $('#div3').append(decodeURIComponent($.param(obj1)) + '<br />');
    return false;
  });
;});

div3. Some initial text.
