Convert configuration item of Field

The field convert configuration item allows you to define how to display data in the field. Example:

{Name: 'name'}, {Name: 'First name' convert: function (value, record) {var firstname = record. get ('name '). firstname; return firstname ;}}

Here, record refers to a piece of data returned. The sample data is in JSON format as an example: {'name': {'firstname': 'jason ', 'lastname': 'ton '}}

In general, we use mapping to handle this problem, but when the name is empty, mapping will report an error (this is found in 4.0.2a). Therefore, this method is the safest, you can judge before referencing.

Note: record. the parameter of the get ('name') method must be the name defined in the field. Even if the data you return contains the name attribute, you did not specify it in the field, it is still not recognized.
