Do not trigger a verification immediately after setting the rules attribute to change
Scenario: If two forms are entered through a switch, it is strange that the switch triggers the first validation if nothing is done.
Solution: Add: validate-on-rule-change="false" attribute
example:
<el-form :rules="rules" :validate-on-rule-change="false" ref="testForm" >
</el-form>
This way the checksum won't be triggered when switching! ! !
Little knowledge (clear prompt content): this.$refs.testForm.clearValidate();
testForm corresponds to the form name defined by itself each time
