Posted 2022-01-14 安果移不动

vue2.0 项目中新增 vuex_丿灬安之若死-CSDN博客

上面是加入vuex 。如果已经添加就不需要管了

 

 具体实现

上篇博客已经导入进来了

调用方法即可

CommonAside.vue

<template>
  <!--    default-active  默认展开项目-->
  <el-menu
      class="el-menu-vertical-demo"
      @open="handleOpen"
      @close="handleClose"
      background-color="#545c64"
      text-color="#fff"
      active-text-color="#ffd04b"
      :collapse="isCollapse">
    <h3 v-show="!isCollapse">通用后台管理系统</h3>
    <h3 v-show="isCollapse">后台</h3>
    <el-menu-item :index="item.path" v-for="item in noChildren " :key=item.path @click="clickMenu(item)">
      <i :class="'el-icon-'+item.icon"></i>
      <span slot="title"> item.label </span>
    </el-menu-item>

    <el-submenu :index="item.label" v-for="item in hasChildren" :key=item.path>
      <template slot="title">
        <i :class="'el-icon-'+item.icon"></i>
        <span slot="title"> item.label </span>
      </template>
      <el-menu-item-group>
        <el-menu-item :index="subItem.path" v-for="(subItem,subIndex) in item.children" :key="subIndex"
                      @click="clickMenu(item)">
          <i :class="'el-icon-'+subItem.icon"></i>
          <span slot="title"> subItem.label </span>
        </el-menu-item>
      </el-menu-item-group>

    </el-submenu>
  </el-menu>
</template>

<style lang="scss" scoped>

.el-menu 
  height: 100%;
  border: none;

  h3 
    color: #ffffff;
    text-align: center;
    line-height: 48px;
  


.el-menu-vertical-demo:not(.el-menu--collapse) 
  width: 200px;
  min-height: 400px;


</style>


<script>

export default 
  name: "CommonAside",
  data() 
    return 
      //展开 还是折叠
      menu: [
        path: "/", name: "home", label: "首页", icon: "s-home", url: "Home/Home",
        path: "/mall", name: "mall", label: "商品管理", icon: "video-play", url: "MallManage/MallManage",
        path: "/user", name: "user", label: "用户管理", icon: "user", url: "UserManage/UserManage",
        
          label: "其他",
          icon: "location",
          children: [
            path: "/page1", name: "page1", label: "页面1", icon: "setting", url: "Other/PageOne",
            path: "/page2", name: "page2", label: "页面2", icon: "setting", url: "Other/PageTwo",
          ]
        ,
      ]
    ;
  ,
  methods: 
    handleOpen(key, keyPath) 
      console.log(key, keyPath);
    ,
    handleClose(key, keyPath) 
      console.log(key, keyPath);
    ,
    clickMenu(item) 
      this.$router.push(name: item.name);
    
  ,
  computed: 
    noChildren() 
      return this.menu.filter((item) => !item.children);
    ,
    hasChildren() 
      return this.menu.filter((item) => item.children);
    ,
    isCollapse() 
      return this.$store.state.tab.isCollapsed;
    
  

</script>

 根据这个状态来进行更新

但是使用的是计算属性

 

CommonHeader.vue 中呢

<template>
  <header>
    <div class="l-content">
      <el-button plain icon="el-icon-menu" size="mini" @click="handleMenu"></el-button>
      <h3 style="color:#fff">首页</h3>
    </div>
    <div class="r-content">
      <el-dropdown trigger="click" size="mini">
        <span class="el-dropdown-link">
          <img :src="userImage" alt="" class="user">
        </span>
        <el-dropdown-menu slot="dropdown">
          <el-dropdown-item>个人中心</el-dropdown-item>
          <el-dropdown-item>退出</el-dropdown-item>
        </el-dropdown-menu>
      </el-dropdown>
    </div>
  </header>
</template>

<script>
export default 
  name: "CommonHeader",
  data() 
    return 
      userImage: require('../assets/image/user.png')
    ;
  ,
  methods: 
    handleMenu() 
      this.$store.commit("collapseMenu");
    
  

</script>

<style scoped lang="scss">
header 
  display: flex;
  height: 100%;
  align-items: center;
  justify-content: space-between;


.l-content 
  display: flex;
  align-items: center;

  .el-button 
    margin-right: 20px;
  



.r-content 
  .user 
    width: 40px;
    height: 40px;
    border-radius: 50%;
  


</style>

 

 针对按钮添加了一个点击事件

 

通过commit触发点击事件
