<el-form :model="ruleForm" status-icon :rules="rules" ref="ruleForm" label-width="100px">

        <el-input v-model.number="ruleForm.phone"/>
    </el-form-item>
</el-form>

export default { data() { var checkPhone = (rule, value, callback) => { if (!value) { return callback(new Error('手机号不能为空')); } else { const reg = /^1[3|4|5|7|8][0-9]\d{8}$/ console.log(reg.test(value)); if (reg.test(value)) { callback(); } else { return callback(new Error('请输入正确的手机号')); } } }; return { ruleForm: { phone: '' }, rules: { phone: [ {validator: checkPhone, trigger: 'blur'} ] } }; } }
