我要评论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
