Select values of checkbox group with jQuery

Question

I m using Zend Form to output a set group of checkboxes    lt label style  white-space  nowrap   gt  lt input type  checkbox  name  user group    id  user group-20  value  20  gt This Group lt  label gt    With a normal HTTP Post these values are passed as an array  but when I m somewhat stumped on how to grab all the values using jQuery  I figured I can select the group using      input  name  user group       val     but that just grabs the value of the first checkbox in the list regardless of if it is checked of not  Any ideas

I just shortened the answer I selected a bit:

var selectedGroups  = new Array();
$("input[@name='user_group[]']:checked").each(function() {
    selectedGroups.push($(this).val());
});

and it works like a charm, thanks!

You could use the checked selector to grab only the selected ones  negating the need to know the count or to iterate over them all yourself       input name  user group     checked     With those checked items  you can either create a collection of those values or do something to the collection   var values   new Array      each    input name  user group     checked    function       values push   this  val          or you can do something to the actual checked checkboxes by working directly with   this       something like   this  hide    only something useful  probably   P

I m not 100  entirely sure how you want to  grab  the values   But if you want to iterate over the checkboxes you can use  each like so     input  name  user group       each  function         alert   this  val           Of course a better selector is available       checkbox

You can have a javascript variable which stores the number of checkboxes that are emitted  i e in the  lt head gt  of the page    lt script type  text javascript  gt  var num cboxes  lt  php echo  number of checkboxes   gt    lt  script gt    So if there are 10 checkboxes  starting from user group-1 to user group-10  in the javascript code you would get their value in this way   var values new Array    for  x 1  x lt  num cboxes  x         values x      user group-    x  val

With map in instead of each it is possible to avoid the array creation step   var checkedCheckboxesValues           input checkbox name  groupName   checked            map function                 return   this  val               get      From the map   page of the docs      Pass each element in the current matched set through a function  producing a new jQuery object containing the return values   get   turns those values into an array

I m not sure about the     used in the selector   At least with the latest jQuery  I had to remove the   to get this to function with two different checkbox arrays  otherwise all checked items were selected for each array   var items          input name  items     checked   each function   items push   this  val         var about          input name  about     checked   each function   about push   this  val          Now both  items and about work
