EasyUi After opening the dialog box the control assignment and the solution to the problem that the control does not display after assignment

1: First of all, the assignment can only be done after the page is loaded, that is, in onLoad;

2: Because the textbox control is used in the input field in dialog, if you need to assign a value, you should call the assignment method of textbox instead of $('#userName').val(row[0].User_name);

Because the textbox control of easyui hides the original input field after initialization, and what the control actually shows is the input field generated by easyui. You can use a browser to view the dom structure after initialization of the control.

So modify the assignment statement to $('#dilog_id').textbox("setValue",row.id); That's enough.
