How to avoid double insertion of two identical records when you double-click the submit button?

Question

I have a popup that has two onclick methods: Submit and Cancel.

When I double-click submit , it inserts two entries that mean duplicate entries.

How can i avoid this?

Answer 1

Prevention of double sending is a common problem.

Despite the fact that there are many solutions since you marked it struts2, two methods are provided by a ready-made framework for double-submit processing:

• Token interceptor

  It returns a result invalid.token, which may, for example, display on an error:

  . , . , , "checkout" -. , : invalid.token, . , TokenSessionStoreInterceptor, , .

  . , token tag. , , . , ( ), .

• Token Interceptor, , - , : submit , , ( ) (-):

  TokenInterceptor, . , . , , invalid.token , , , .
