简介模仿风宇博客登录蒙层弹窗(vuex+computed实现)

效果图

在这里插入图片描述

  • 使用了动态组件做组件切换
  • 使用vue内置的transition组件实现过渡效果,蒙层 和 弹框 都使用了transition,并嵌套
  • vuex + computed计算属性,实现数据 和 方法共享,让其它组件也能够控制到登录弹框
  • 蒙层使用了固定定位
  • 未实现:鼠标滚轮在蒙层上面滚动时,蒙层下面的页面也会滚动。但是,我不想使用body,overflow:hidden,这种方式,这样右侧的滚动条就会消失掉,还没找到方法。(已解决:参考-蒙层禁止页面滚动
  • 未实现:页面会立即回到顶部(已解决:参考-蒙层禁止页面滚动))
  • 与原博客中有差异,我的是弹出来后,下面的页面静止不动了,仍然有滚动条,但滚动条里的滑块没了
  • 有其他定位相关的问题,影响了其它页面布局
    • 试了下,把这个问题解决了,只要给body加上width:100%,就解决了全部的问题(1. 有轻微的抖动,2. 其它页面的布局被搞乱了)

    • 最终的效果图如下(以下代码是最新代码):

代码

App.vue

  • 直接将Login这个组件,放入App.vue中,而Login组件使用固定定位,覆盖掉整个视口,然后,使用flex布局,让弹窗内容在中间。
<template>
  <div id="app">
      <router-view/>
    <Login/>
    <Search/>
  </div>
</template>

<script>
import Login from '@/components/model/Login.vue';
import Search from '@/components/model/Search.vue';

  export default {
    name:'App',
    data() {
      return {
        
      }
    },
    components: {
      Login,
      Search
    }
  }
</script>

    overflow-y: scroll !important;
    overflow-x: hidden;

    width: 100%;

store/index.js

  • loginShow控制最外面的蒙层的v-show(即display:none)
  • componentName控制动态组件切换的组件名
  • loginShow 和 componentName都存到vuex中,提供方法入口给外界,去修改这两个值
  • 这两个值,会被Login组件使用,控制展示蒙层 和 切换的动态组件
import Vue from 'vue'
import Vuex from 'vuex'
import router from '@/router'

Vue.use(Vuex)

export default new Vuex.Store({
  state: {
    loginShow: false,
    componentName: '',
    scrollTop1:0
  },
  getters: {

  },
  mutations: {
    updateComponentName(state, val) {
      state.componentName = val
    },
    updateLoginShow(state, val) {
      state.loginShow = val
    },
    showComponentName(state,componentName){

	  /* 记录此时的滚动距离 */
      let documentTop = document.scrollingElement.scrollTop;
      state.scrollTop1 = documentTop
      
      /* 调用其它mutation中的方法 */
      this.commit('updateComponentName',componentName)
      this.commit('updateLoginShow',true)
		
	  /* 保持滚动距离 */
      this._vm.$nextTick(()=>{
        document.body.style.position = "fixed"
        document.body.style.top = -state.scrollTop1 + "px";
      })
    }
  },
  actions: {
  },
  modules: {
  }
})

Login.vue

  • 给 蒙层(使用了v-show,支持过渡) 和 动态组件(动态组件支持过渡) 添加过渡样式
  • 使用 计算属性 配合使用 vuex
  • 点击蒙层时,调用vuex提供的方法,修改store中的值,然后,计算属性接收到修改的值,从而更新渲染(动态组件消失,蒙层隐藏)

NavBar.vue

直接调用vuex暴露出来的方法,来修改store中的值,Login组件接收到修改的值,从而更新渲染(动态组件更新,并展示蒙层)

<li>
    <a class="menu-a" href="#">
        <i class="iconfont icon-denglu"></i>
        <span @click="$store.commit('showComponentName', 'LoginBox')">登录</span>
    </a>
</li>
