Vue项目elementUI中封装表单验证
1.直接在Vue文件中使用验证:<template><div class="login-wrap"><div class="ms-title">后台管理系统</div><div class="ms-login"&a

1.直接在Vue文件中使用验证:
<template>
<div class="login-wrap">
<div class="ms-title">后台管理系统</div>
<div class="ms-login">
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="0px" class="demo-ruleForm">
<el-form-item prop="username">
<el-input v-model="ruleForm.username" placeholder="username"></el-input>
</el-form-item>
<el-form-item prop="password">
<el-input type="password" placeholder="password" v-model="ruleForm.password" @keyup.enter.native="submitForm('ruleForm')"></el-input>
</el-form-item>
<div class="login-btn">
<el-button type="primary" @click="submitForm('ruleForm')">登录</el-button>
</div>
<p style="font-size:12px;line-height:30px;color:#999;">Tips : 用户名和密码随便填。</p>
</el-form>
</div>
</div>
</template>
<script>
export default {
data: function() {
let checkName = (rule, value, cb) => {
this.$store.commit('checkName',{rule,value,cb});
};
return {
ruleForm: {
username: "admin",
password: "123123"
},
rules: {
username: [
{ required: true, message: "请输入用户名", trigger: "blur" },
{ validator: checkName }
// { min:10 , message:'最少10个字符',trigger:'blur'},
// { pattern: /^[\u4E00-\u9FA5]+$/, message:'用户名只能是中文'},
// { pattern:/^[a-zA-Z]w{5,17}$/, message: '以字母开头,长度在6-18之间, 只能包含字符、数字和下划线'}
],
password: [{ required: true, message: "请输入密码", trigger: "blur" }]
}
};
},
methods: {
submitForm(formName) {
this.$refs[formName].validate(valid => {
if (valid) {
localStorage.setItem("ms_username", this.ruleForm.username);
this.$router.push("/");
} else {
console.log("error submit!!");
return false;
}
});
}
}
};
</script>
2. 使用vuex将需要用到的表单验证写在mutations.js文件中
这需要安装vuex,步骤是:
- cnpm i vuex --save
- store/index.js
import Vue from 'vue'; import Vuex from 'vuex'; import state from './state'; import mutations from './mutations'; import actions from './actions'; Vue.use(Vuex); const store = new Vuex.Store({ state, mutations, actions }); export default store;
- store/mutations_type.js
export const CHECK_NAME = 'checkName';
- store/mutations.js
import {
CHECK_NAME
} from './mutations_type';
export default {
[CHECK_NAME](state , obj){
if(!obj.value){
obj.cb(new Error('请输入用户名'));
}else if(!/^[\u4E00-\u9FA5]+$/.test(obj.value)){
obj.cb(new Error('用户名只能是中文'));
}else{
obj.cb();
}
}
}
- 将vuex引入main.js
-
import store from './store/index'; Vue.prototype.$store = store;
