Why doesn't validate in vue enter?

The reasons why the validate function does not enter are: unbound model, incorrect call, undefined validation rules, improper use of v-model, field disabled, incorrect submit button type, JavaScript error, asynchronous validation.

##validate in Vue Why not enter

Use

validate in Vue , you may encounter a situation where the function will not be entered. The following are some possible reasons:

1. The form field is not bound to the model

validate The form field that the function needs to validate must be bound to the Vue model. Without binding, validate will not find the field to validate.

2. validate The function was not called correctly

validate The function must be called with specific syntax. For example:

this.$refs.form.validate();

Make sure the function is called with correct syntax.

3. The form validation rules are not defined correctly

validate The function requires validation rules to determine whether a field is valid. Make sure that the form validation rules are defined correctly and match the field's value.

4. The v-model directive is not used correctly. The

v-model directive is used for two-way binding of form fields. . If the v-model directive is not used correctly, form fields may not validate.

5. disabled attribute is set

If the form field is disabled (e.g. via the

disabled attribute), The validate function will not validate this field.

6. The form submission button type is incorrect

The type of the form submission button must be

submit, otherwise validate function will not be triggered.

7. JavaScript Errors

JavaScript errors that occur during validation may prevent the

validate function from entering. Check if there are any errors and fix them.

8. Asynchronous verification

If the verification is asynchronous, the

validate function may not enter immediately. Check if asynchronous validation is being used, if so, wait for validation to complete.
