runtime-core.esm-bundler.js?d2dd:218 Uncaught TypeError: formRef.value?.validate is not a function

1.vue3 uses the elemetPlus component. When writing the form verification, when the verification method is also logged in the setup, we get the component object, but when calling the attribute method of the component object, it is found that the method printed on the console is invalid.Written on the Internet to find many solutions have not been resolved.Most of the online solutions are vue2 use solutions.

The solution code is as follows:

Conjecture may be the reason why elementplus is only compatible with script setup.
