• Send multiple checkbox data to PHP via jQuery ajax() 6 answers

How can I send all the checked item into php using AJAX. The info I expect to send including checkbox id and checkbox inner text. e.g. If I check box1 and box2, it could save the useful info into Data then sent to php when I click submit.

I try to use serialize() in javascript, however the Date has always been "".

var Data = $('#myform').serialize(); 

Please notice that I don not expect realtime respond when I check each box. I just wanna send the entire checked list after I click "submit".

<form class="myform" id="myform" action="add.php">
  <input type="checkbox" class="checkBox[]" id="1"> 1
  <input type="checkbox" class="checkBox[]" id="2"> 2
  <input type="checkbox" class="checkBox[]" id="3"> 3
  <input type="submit" class="add" id="add" name="add">
<form>

</div>

Simply you can use this code

var checkBox= new Array();
$("input:checked").each(function() {
   data['checkBox[]'].push($(this).val());
});
