Check if a JQuery mobile checkbox is checked

Question

I have a list of Checkboxes & I want to get the status of each one of them. The List is here :

<div data-role="fieldcontain">
    <fieldset data-role="controlgroup">
       <input type="checkbox" name="Sunday" id="Sunday-1" class="custom" />
       <label for="Sunday-1">Sunday</label>
       <input type="checkbox" name="Monday" id="Monday-1" class="custom" />
       <label for="Monday-1">Monday</label>
       <input type="checkbox" name="Tuesday" id="Tuesday-1" class="custom" />
       <label for="Tuesday-1">Tuesday</label>
  </fieldset>
</div>

I usually Check the checkbox's status using this quote:

var isChecked = $('#CheckboxID').is(':checked');

But in my case now, is there a method to get the status of "Jquery Mobile" checkboxes all at once ?

Answer 1

You can do

var status = $('input[type="checkbox"]').filter('.custom').map(function(){
    return $(this).is(':checked') ? 1 : 0;

});

Then the status array will have an entry for each checkbox in the same order, 0 for unchecked and 1 for checked. It's not much of useful as you have no other information of the checkbox in the array.

If you want to perform operation based on the status you can use .each() instead, like

$('input[type="checkbox"]').filter('.custom').each(function(){
   if($(this).is(':checked')){
     // perform operation for checked
   }
   else{
     // perform operation for unchecked
   }

});

UPDATE

If you want to build an array of objects with the name and status of the checkboxes you can do that with

var status = $('input[type="checkbox"]').filter('.custom').map(function(){
    var name = $(this).attr('name'); 
    if($(this).is(':checked'))
         return { 'name':name, 'status' : 'Checked'}; 
    else
        return { 'name':name, 'status' : 'UnChecked'};

});

console.log(status);​

I have this code. I think you should adjust to your case.

  $('#formfriends input[type=checkbox]').each(function() {
    if ($(this).attr('checked'))
     //$(this).attr('disabled' , true);
     // do what you want here
  });
