Darius,

是的，这可以通过代码实现。如果使用JavaScript / jQuery，则可以使用PreSaveAction函数创建代码文件。在此，您将检查所选值，然后检查单行文本字段的长度。然后使用代码验证它是否合适。

Yes this is possible with code. If you use JavaScript/jQuery you can create a code file with a PreSaveAction function. In this you would check the value selected and then the length of the single line of text field. Then use the code to validate it fits.

PreSaveAction函数在SharePoint保存之前触发。

The PreSaveAction function fires right before SharePoint saves.
