Two easyui DataGrid 1.4 requests

When the returned data is {rows: [], total: 0}, the DataGrid requests twice.

Problems with the framework itself are hard to find out the cause, and Google eventually finds a solution in the easyui community.

The attachment is the bug fixing code of version 1.4. You only need to add this JS Code after the JS is imported to the page (note that it should be placed behind easyui. Min. JS)

Attachments cannot be uploaded, depressing
