================= on_field_get_text ================= on_field_get_text(field) **domain**: client **language**: javascript **class** :doc:`Item class ` Description =========== Write an ``on_field_get_text`` event handler to perform custom processing for the :doc:`display_text ` property. If the event handler does not return a value, the application uses the :doc:`display_text ` property value to display the field value in the data-aware controls, otherwise the returned value will be used. The ``field`` parameter is the field whose :doc:`display_text ` is processed. To get the item that owns the field, use the :doc:`owner ` attribute of the field. Example ======= .. code-block:: js function on_field_get_text(field) { if (field.field_name === 'customer') { return field.owner.firstname.lookup_text + ' ' + field.lookup_text; } } See also ======== :doc:`Fields `
