What the program should do.
Get form elements, bind events
When there is input, get the form value, use the rules specified by the developer for verification, and give an error prompt if the verification error.
Realization method
To get the native form element, the vue instruction gets the outer element that wraps the native form element. Here I use the data-type attribute to get the native form element
Validation rules, validation parameters, and custom error prompts are obtained from the instruction values of vue
When submitting, we need a form identity, and here I use the data-scope attribute to group the forms
Reset, reset the entire form through data-scope
Common methods
Lazy verification, passing the .lazy instruction modifier
Remote authentication, through asyncawait
