本文介紹了在Vue.js中使用表單校驗規(guī)則（rules）進行網(wǎng)絡(luò)請求校驗的方法,以及如何通過formRef引用表單對象并進行鍵盤按鍵監(jiān)聽,感興趣的朋友跟隨小編一起看看吧

Form表單

rules格式校驗

可以在validator中進行網(wǎng)絡(luò)請求，實現(xiàn)網(wǎng)絡(luò)校驗

const formRules = {
  userName: [{required: true, message: "用戶名不能為空", trigger: 'blur'}, {
    min: 5,
    max: 10,
    message: "長度必須5-10位",
    trigger: 'blur'
  }],
  passWord: [{required: true, message: "密碼不能為空", trigger: 'blur'}],
  reference: [{
    validator: referenceValidity,
    required: true,
    trigger: "blur",
  },],
}
function referenceValidity(rule, value, callback) {
  console.log('校驗推薦人')
  if (value === "" || value === undefined) {
    callback(new Error("請輸入推薦人姓名"));
  } else {
    //請求網(wǎng)絡(luò)校驗推廣人
    // console.log("輸入的推薦人姓名：" + 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("推薦人不存在"))
    //     }
    //   } else {
    //     callback(new Error("推薦人不存在"))
    //   }
    // });
    callback(new Error("推薦人不存在"))
  }
}

formRef引用form對象 form表單中關(guān)聯(lián)formRef（引用對象），form（表單內(nèi)容），formRules（校驗規(guī)則）

<el-form ref="formRef" :model="form" :rules="formRules">

const formRef = ref()
function reqLogin() {
  console.log("賬號信息", form.value)
  formRef.value.validate((valid) => {
    console.log("formRef valid = ", valid)
    if (valid) {
      setToken()
      store.commit("setUserInfo", form.value)
      showToast("登錄成功")
      router.push('/')
    }
  })
}

鍵盤監(jiān)聽

onMounted(() => {
  console.log("頁面加載")
  document.addEventListener('keyup', onkeyup)
})
onBeforeUnmount(() => {
  document.removeEventListener('keyup', onkeyup)
})
function onkeyup(e) {
  if (e.key === 'Enter') {
    reqLogin()
  }
}

    min: 5,

    message: "長度必須5-10位",
    trigger: 'blur'
  }],
  passWord: [{required: true, message: "密碼不能為空", trigger: 'blur'}],
  reference: [{
    validator: referenceValidity,
    required: true,
    trigger: "blur",
  },],
}
function referenceValidity(rule, value, callback) {
  console.log('校驗推薦人')
  if (value === "" || value === undefined) {
    callback(new Error("請輸入推薦人姓名"));
  } else {
    //請求網(wǎng)絡(luò)校驗推廣人
    // console.log("輸入的推薦人姓名：" + 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("推薦人不存在"))
    //     }
    //   } else {
