I always forget how to create javascript singleton objects.

javascript-singleton.js

    var obj_ea = new function() {
      this.url = 'some_ajax_url.php';
      this.submit_actions = function() {
        var data = {
          'id': 'e04b7291',
          'email': $('#email1').val(), 
          'status': $('#status1').val(),
          'email_pre_cust': $('#email4').attr('checked'),
          'email_pre_fire': $('#email5').attr('checked'),
          'email_approved': $('#email3').attr('checked'),
          'email_denied'  : $('#email2').attr('checked'),
          'expired_date'  : $('#expiration').attr('checked')};  
        $.ajax({
          url:this.url,
          type:'POST',
          data:data,
          success: function(response) { rep = JSON.parse(response); if (rep.RELOAD) {location.reload();} }
        }); 
      }
    }
