Question

I have a table with checkboxes, and I am posting it by clicking <a id='fecth_details'... as:

  $('#fetch_details').click(function(e) {
    e.preventDefault();
    var data = { 'selected_sales[]' : []};
    $("input[name='salesID[]']:checked").each(function() {
      data['selected_sales[]'].push($(this).val());
    });
    $('#list_data').html('');
    $.post('fetch_sales_details',data,function (data) { $('#list_data').html(data)});
  });

I need to control it if it is empty or not. Basically testing like:

var data = ({ 'choices[]': ["Jon", "Susan"] });
alert(data);
if ($.isEmptyObject(data.choices))
{
   alert('it is an empty object');
}
else
{
    alert('auch! I am not empty');
}

But not working… I shouldn’t work if no checkbox is checked.

Answer 1

try

   $('#fetch_details').click(function(e) {
        e.preventDefault();
      if(!$(":checkbox:checked").length>0){//atleast one checkbox is checked
        //your code here
        //
