How to save edit form without closing it 
========================================

You can do it by adding a button that will save the record without closing the
edit form.

Below is examples for synchronous and asynchronous cases.

.. code-block:: js

  function on_edit_form_created(item) {
      var save_btn = item.add_edit_button('Save and continue');
      save_btn.click(function() {
          if (item.is_changing()) {
              item.post();
              try {
                item.apply();
              }
              catch (e) {
                item.alert_error(error);
              }
              item.edit();
          }
      });
  }

.. code-block:: js

  function on_edit_form_created(item) {
      var save_btn = item.add_edit_button('Save and continue');
      save_btn.click(function() {
          if (item.is_changing()) {
              item.disable_edit_form();
              item.post();
              item.apply(function(error){
                  if (error) {
                      item.alert_error(error);
                  }
                  item.edit();                
                  item.enable_edit_form();
              });
          }
      });
  }
