Question

jquery sum checked + select all

Answer 1

A:

You forgot type="text/javascript" on your third <script> tag. That could be part of it...

Answer 2

+1 A:

Try this, it can actually fit into one line:

$(document).ready( function() {
    $('#paradigm_all').click(function() {
          $(".chkOptions").attr('checked', $('#paradigm_all').is(':checked'));   
       }
    ));
});

If that does not trigger the recalculation, maybe try triggering the click event on the chkOptions:

$(".chkOptions").attr('checked', $('#paradigm_all').is(':checked')).each(function() {
    $(this).click();
});

Answer 3

A:

The sum is not calculated anywhere in the "select all" callback... the ugly way would be to just copy-paste it from the other function like this:

$(document).ready(function()
{
  $("#paradigm_all").click(function()      
  {
    var checked_status = this.checked;
    var ntot = 0;
    $("input[name=paradigm]").each(function()
    {
      if (checked_status) ntot += parseInt($(this).val());
      this.checked = checked_status;
    });
    $("#PaymentTotal").val(ntot);

  });       
});

...a bit prettier way would be to separate the calculation of the sum to it's own function and call it from the both callbacks. In the process you could combine the two script tags and the two $(document).ready callbacks:

function updateSum() {
  var ntot = 0;
  $("input.chkOptions:checked").each(function() {
    ntot += parseInt($(this).val());
  });
  $("#PaymentTotal").val(ntot);
}    

$(document).ready(function() {
  $(".chkOptions").click(function() {
    updateSum();
  });

  $('#paradigm_all').click(function() {
    $("input[type='checkbox']").attr('checked', $('#paradigm_all').is(':checked'));   
    updateSum();
  });


});
