确认只测试数据是否与标识域的规则一致，（从语法上来说是正确的）；它不根据第二个数据源验证数据。
Validation only tests that the data is in accordance with the rules identified for that field (syntactically correct); it does not verify the data against a second data source.
一旦您验证了数据源工作正常，请选择OK。
Once you have verified the data source is working, select OK.
数据验证几乎总是只在服务器上进行，因为要根据一个数据源对数据进行验证。
Verification of data should almost always only be done on the server, because the data is going to be validated against a data source.
