renderings

1. template part

<div>
    <el-form ref="form" label-width="70px" :inline="true" class="login-container" :model="form" :rules="rules">
      <h3 class="login_title">系统登录</h3>

        <el-form-item label="用户名" prop="userName">
            <el-input v-model="form.userName" placeholder="请输入账号"></el-input>
        </el-form-item>

        <el-form-item label="密码" prop="password">
            <el-input show-password v-model="form.password" placeholder="请输入密码"></el-input>
        </el-form-item>

        <el-form-item>
            <el-button @click="submit" class="login_button" type="primary"> 登 录 </el-button>
        </el-form-item>


    </el-form>
  </div>

2. style part

Here I use less to write,

Need to download less and less-loader

<style lang="less" scoped>
.login-container {
  width: 400px;
  border:1px solid #eaeaea;
  margin: 180px auto;
  padding: 35px 35px 15px 35px;
  border-radius: 15px;
  box-shadow: 0 0 25px #cac6c6;
  background-color: #ffffff;
  box-sizing: border-box;
  .login_title {
    text-align: center;
    margin-bottom: 40px;
    color: #505458;
  }
  .el-input {
    width: 198px;
  }
  .login_button {
    margin-left: 105px;
    margin-top: 10px;
  }
  .login_register {
    width: 70px;
    height: 40px;
    text-align: center;
    margin-top: 10px;
  }
}

3. vue part

(1). Introduce the encapsulated axios interface to facilitate subsequent joint debugging

import {GetLogin} from "@/Api/api";

Everyone's different here, this is just my encapsulation

(2) Form

trigger

trigger method

String

click/focus/hover/manual

click

required

Is it required? If not set, it will be automatically generated according to the verification rules

boolean

—

false

blur

Triggered when the Input loses focus

(event: Event)

data() {
    return {
      form: {
        userName:'',
        password:'',
      },
      rules: {
        userName: [
          {
            required: true,
            trigger: 'blur',
            message: '长度在6到16个字符',
            min: 6, max: 16,
          }
        ],
        password: [
          {
            required: true,
            trigger: 'blur',
            message: '请输入密码',
            min: 6, max: 16,

          }
        ],
      }
    }
  },

(3).methods section

validate

The method to validate the entire form, the parameter is a callback function. The callback function will be called after the verification is completed, and two parameters are passed in: whether the verification is successful and the field that failed the verification. If no callback function is passed in, a promise will be returned

Function(callback: Function(boolean, object))

methods: {
    //提交方法
    submit() {
        this.$refs.validate((valid) => {
          if (valid) {
            // 封装的接口使用
            GetLogin({
              // 表单的数据
              userName: this.form.userName,
              password: this.form.password,
            }).then(({data}) => {
              // console.log(data)
              if (data.code === 200) {
                //将token存储在本地
                localStorage.setItem('token',data.data.token)
                //若登录成功则跳转到指定路由
                this.$router.push('/')
              } else {
                this.$message.error(data.data.rules.message)
              }
            })
          }
        })
    }
  }

4. Complete code

<template>
  <div>
    <el-form ref="form" label-width="70px" :inline="true" class="login-container" :model="form" :rules="rules">
      <h3 class="login_title">系统登录</h3>

        <el-form-item label="用户名" prop="userName">
            <el-input v-model="form.userName" placeholder="请输入账号"></el-input>
        </el-form-item>

        <el-form-item label="密码" prop="password">
            <el-input show-password v-model="form.password" placeholder="请输入密码"></el-input>
        </el-form-item>

        <el-form-item>
            <el-button @click="submit" class="login_button" type="primary"> 登 录 </el-button>
        </el-form-item>


    </el-form>
