Usage tutorial

New form

Display

method processing

methods:{ async checkValid () { // 是否验证通过 return this.$refs.form.validate(); }, async handleAddAddress(e){ let check = await this.checkValid(); if(! check) // 验证不通过 { let errors = Object.values(this.$refs.form.errors); let first_error_index = errors.findIndex(val => val.length >= 1); alert(errors[first_error_index][0]) } // 弹出请输入11位的手机号码 ...... }

this.$refs.form.validate()是一个promise,当然你也可以用then

inputshould be encapsulated into a custom component)
