Description

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

When used while multi-row editing, this method has the following behaviour:

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