Description

It is often useful to be able to get and set the value of a field, or multiple fields, for example in client-side validation, or data manipulation. This method provides that ability for one or more fields in a form.

When used wile multi-row editing, the values returned and set for fields have the following behaviour for this method:

  • As a getter, for each field:
    • If all items being edited have the same value for the field, that value is returned
    • If the items being edited have different values for the field, undefined is returned. multiGet() or field().multiGet() should be used to access individual values if this is the case.
  • As a setter, for each field:
    • The field value is set to the same value for all items being edited. Use multiSet() or field().multiSet() to set individual values if required.

In addition to this method, Editor provides a number of other methods that can be used to get and set field values - each with their own speciality. Please refer to the Related selection below for links to these methods.
