No logic is executed after the El form is validated successfully

form Forms validate No logic is executed after success

01. Problem analysis

1. The prompt will be executed when the verification form fails , No logic is executed after passing , As shown in the figure below

2. According to the correct logic , The console will output success, But the task logic is not executed after the verification , Therefore, it is the method return problem after the validation rule passes

02. View existing rules

1. see form Forms rules Logic , As shown in the figure below

2. The age is verified in the figure , Prompt for null value

3. Most of the time, I feel that there is no problem in such verification , But only the wrong logic is executed here , Not executing the correct logic , Therefore, it is necessary to execute the correct logic when it is worth it

03. Problem solving

1. Add correct processing logic to the verification method , As shown in the figure below

2. Added callbak() Method , Used for logical execution after verification

Be careful

1. All methods of customizing validation rules , whatever （ situation ） It needs to be implemented in all cases callback() Method
