Vue实现简单视图模板（登录，后台）

1.登录

<template>
  <div>
    <el-form ref="loginForm" :model="form" :rules="rules" label-width="80px" class="login-box">
      <h3 class="login-title">欢迎登录</h3>
      <el-form-item label="账号" prop="username">
        <el-input type="text" placeholder="请输入账号" v-model="form.username"/>
      </el-form-item>
      <el-form-item label="密码" prop="password">
        <el-input type="password" placeholder="请输入密码" v-model="form.password"/>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" v-on:click="onSubmit('loginForm')">登录</el-button>
      </el-form-item>
    </el-form>

    <el-dialog
      title="温馨提示"
      :visible.sync="dialogVisible"
      width="30%"
      :before-close="handleClose">
      <span>请输入账号和密码</span>
      <span slot="footer" class="dialog-footer">
        <el-button type="primary" @click="dialogVisible = false">确 定</el-button>
      </span>
    </el-dialog>
  </div>
</template>

<script>
export  default {
  name:"Login",
  data(){
    return {
      form:{
        username: '',
        password: ''
      },
      //表单验证，需要再el-form-item 元素中增加prop属性
      rules:{
        username:[
            {required:true,message:'账号不能为空',trigger:'blur'}
          ],
    password:[
    {required: true,message: '密码不能为空',trigger:'blur'}
          ]
  },
    //对话框显示和隐藏
    dialogVisible:false
  }
  },
  methods:{
    onSubmit(formName) {
      //为表单绑定验证功能
      this.$refs[formName].validate((valid) =>{
        if (valid){
          //使用 vue-router路由到指定页面，该方式称之为编程式导航
          this.$router.push("/main");
        } else {
          this.dialogVisible = true;
          return false;
        }
      });
    }
  }
}
</script>

<style lang="scss" scoped>
.login-box{
  border: 1px solid #DCDFE6;
  width: 350px;
  margin:180px auto;
  padding:35px 35px 15px 35px;
  border-radius: 5px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  box-shadow:0 0 25px #909399;
}

.login-title{
  text-align:center;
  margin:0 auto 40px auto;
  color:#303133;
}
</style>

2.url路径错误
