3.处理前端登录事件

在登录按钮加上点击事件

<el-button type="primary" style="width:100%" @click="submitLogin">登录</el-button>

添加method

methods:{
            submitLogin(){
                this.$refs.loginForm.validate((valid) => {
                    if(valid){
                        alert('submit');
                    }else{
                        this.$message.error('请输入所有字段')
                        return false;
                    }
                });
            }
        }

Login.vue全部代码

<template>
    <div>
        <el-form :rules="rules" ref="loginForm" :model="loginForm" class="loginContainer">
            <h3 class="loginTitle">系统登录</h3>
            <el-form-item prop="username">
                <el-input type="text" v-model="loginForm.username" auto-complete="off"
                          placeholder="请输入用户名"></el-input>
            </el-form-item>
            <el-form-item prop="password">
                <el-input type="password" v-model="loginForm.password" auto-complete="off"
                          placeholder="请输入密码"></el-input>
            </el-form-item>
            <el-checkbox class="loginRemember" v-model="checked"></el-checkbox>
            <el-button type="primary" style="width:100%" @click="submitLogin">登录</el-button>
        </el-form>
    </div>
</template>

<script>
    export default {
        name: "Login",
        data(){
            return {
                loginForm: {
                    username: 'admin',
                    password: '123'
                },
                checked:true,
                rules: {
                    username: [{required: true, message: '请输入用户名', trigger: 'blur'}],
                    password: [{required: true, message: '请输入密码', trigger: 'blur'}]
                }
            }
        },
        methods:{
            submitLogin(){
                this.$refs.loginForm.validate((valid) => {
                    if(valid){
                        alert('submit');
                    }else{
                        this.$message.error('请输入所有字段')
                        return false;
                    }
                });
            }
        }
    }
</script>
