Vue Form表单的使用方法(rules格式校验网络校验键盘按键监听)
作者：张雨zy
本文介绍了在Vue.js中使用表单校验规则（rules）进行网络请求校验的方法,以及如何通过formRef引用表单对象并进行键盘按键监听,感兴趣的朋友跟随小编一起看看吧
Form表单
rules格式校验
可以在validator中进行网络请求，实现网络校验
const formRules = {
userName: [{required: true, message: "用户名不能为空", trigger: 'blur'}, {
min: 5,
max: 10,
message: "长度必须5-10位",
trigger: 'blur'
}],
passWord: [{required: true, message: "密码不能为空", trigger: 'blur'}],
reference: [{
validator: referenceValidity,
required: true,
trigger: "blur",
},],
}
function referenceValidity(rule, value, callback) {
console.log('校验推荐人')
if (value === "" || value === undefined) {
callback(new Error("请输入推荐人姓名"));
} else {
//请求网络校验推广人
// console.log("输入的推荐人姓名：" + value)
// const _url = "xxxxxxxxxxx";
// let param = {};
// param.promotionPecialistName = value;
// get(this.$http, _url, param).then(function (response) {
// let res = response.data;
// if (res.code === "I000000") {
// if (res.data.isFlag) {
// callback()
// } else {
// callback(new Error("推荐人不存在"))
// }
// } else {
// callback(new Error("推荐人不存在"))
// }
// });
callback(new Error("推荐人不存在"))
}
}formRef引用form对象 form表单中关联formRef（引用对象），form（表单内容），formRules（校验规则）
<el-form ref="formRef" :model="form" :rules="formRules">
const formRef = ref()
function reqLogin() {
console.log("账号信息", form.value)
formRef.value.validate((valid) => {
console.log("formRef valid = ", valid)
if (valid) {
setToken()
store.commit("setUserInfo", form.value)
showToast("登录成功")
router.push('/')
}
})
}键盘监听
onMounted(() => {
console.log("页面加载")
document.addEventListener('keyup', onkeyup)
})
onBeforeUnmount(() => {
document.removeEventListener('keyup', onkeyup)
})
function onkeyup(e) {
if (e.key === 'Enter') {
reqLogin()
}
}完整代码
<script setup>
import {onBeforeUnmount, onMounted, ref} from "vue";
import {Lock, User} from "@element-plus/icons-vue";

const router = useRouter()
const store = useStore()
const form = ref({
userName: "",
passWord: "",
reference: ""
})
const formRef = ref()
const formRules = {
userName: [{required: true, message: "用户名不能为空", trigger: 'blur'}, {
min: 5,
max: 10,
message: "长度必须5-10位",
trigger: 'blur'
}],
passWord: [{required: true, message: "密码不能为空", trigger: 'blur'}],
reference: [{
validator: referenceValidity,
required: true,
trigger: "blur",
},],
}
function referenceValidity(rule, value, callback) {
console.log('校验推荐人')
if (value === "" || value === undefined) {
callback(new Error("请输入推荐人姓名"));
} else {
//请求网络校验推广人
// console.log("输入的推荐人姓名：" + value)
// const _url = "xxxxxxxxxxx";
// let param = {};
// param.promotionPecialistName = value;
// get(this.$http, _url, param).then(function (response) {

callback(new Error("推荐人不存在"))

function onkeyup(e) {

onMounted(() => {
console.log("页面加载")
document.addEventListener('keyup', onkeyup)

onBeforeUnmount(() => {
document.removeEventListener('keyup', onkeyup)

function reqLogin() {
console.log("账号信息", form.value)
formRef.value.validate((valid) => {
console.log("formRef valid = ", valid)
if (valid) {
setToken()
store.commit("setUserInfo", form.value)
showToast("登录成功")
router.push('/')
