Vue集成Iframe页面的方法示例

1. 项目需求

我们切换为vue框架是后面的事情，之前还有一些功能页面是用jsp页面写的，而我们的管理系统需要既支持Vue的url，又要支持这些发布之后的jsp页面

还有一个就是切换tab回来的时候之前输入的东西还要存在

2. 实现思路

针对这个问题，我们最开始的实现思路是写了一个iframe的通用组件，然后把不同的http的页面的url传递进来进行切换，但是这样不满足第二条，我们发现只要切换了vue的路由，然后再切回http的页面，iframe中的src属性的页面就会从新刷新，没有办法保留住东西，于是就有了下面的实现思路

我们在vue的router-view同级别添加了一个iframeTemp组件，其实就是一个elementUI的tab组件，然后把tab组件的头的样式隐藏在我们菜单栏的下面



 .position {
  position: relative
 }

 .router-out-content {
  position: static;
 }



 

 #fwIframe {
  
  
  
  
  
  
  position: absolute;
  left: 0;
  right: 0;
  top: 45px;
  bottom: 0;
  z-index: 5000 !important;
  .el-tab-pane {
   height: 100%;
   width: 100%;
   iframe {
    
    min-height: 600px;
    
    width: 100%;
   }

  }
  .full {
   position: relative;
   left: 0;
   right: 0;
   top: 0;
   bottom: 0;
  }
 }

之后的ifram组件的显示隐藏和tab切换，都是通用vuex和bus事件广播实现的





export const G_GET_NAVTABDATA = 'G_GET_NAVTABDATA'


// 一级tab处理
export const M_PUSH_NAVTABDATA = 'M_PUSH_NAVTABDATA'
export const M_DELETE_NAVTABDATA = 'M_DELETE_NAVTABDATA'
export const M_UPDATE_NAVTABDATA = 'M_UPDATE_NAVTABDATA'

// iframe切换处理
export const M_SHOW_Iframe = 'M_SHOW_Iframe'
export const M_HIDE_Iframe = 'M_HIDE_Iframe'

// iframe添加，删除，选择处理
export const M_Iframe_PUSH_TAB='M_Iframe_PUSH_TAB'
export const M_Iframe_DELETE_TAB='M_Iframe_DELETE_TAB'
export const M_Iframe_CHANGE_SELECTCODE='M_Iframe_CHANGE_SELECTCODE'

// 设置全局系统变量
export const M_SET_SYSTEMNAME = 'M_SET_SYSTEMNAME'


// export const A_REQUEST_DATA = 'A_REQUEST_DATA'



import * as mainConst from './mainConst.js'

export default {
 state: {
  // 一级Tab导航数据集合
  navTabdata: [],
  // 进入的主系统前缀
  systemName:'',
  // 控制路由同级的Iframe的显示隐藏
  showIframe: false,
  // iframe页面中的选中页签的code值
  iframeSelectTab:'',
  // iframe页面的tab数据集合
  iframetabdata:[]

 },
 getters: {
  [mainConst.G_GET_NAVTABDATA](state, getters){
   return state.navTabData
  }
 },
 mutations: {
  // 一级tab处理
  [mainConst.M_UPDATE_NAVTABDATA](state, payload){
   const index = payload.navIndex
   state.navTabData.forEach((item)=> {
    item.active = false
   })

   // 当你利用索引直接设置一个项时是不能触发视图的从新渲染的,下面是老方法和解决办法
   // state.navTabData[index].active=true
   let newItem = Object.assign({}, state.navTabData[index], {active: true})
   // console.log(newItem, 'store newItem')
   state.navTabData.splice(index, 1, newItem)
  },
  [mainConst.M_PUSH_NAVTABDATA] (state, payload) {
   state.navTabData.push(payload)
  },
  [mainConst.M_DELETE_NAVTABDATA] (state, payload) {
   state.navTabData.splice(payload.navIndex, 1)
  },
  // Iframe显示隐藏切换处理
  [mainConst.M_SHOW_Iframe] (state, payload) {
   state.showIframe = true
  },
  [mainConst.M_HIDE_Iframe] (state, payload) {
   state.showIframe = false
  },
  // Iframe添加，删除，选中处理
  [mainConst.M_Iframe_PUSH_TAB] (state, payload) {
   state.iframetabData.push(payload)
  },
  [mainConst.M_Iframe_DELETE_TAB] (state, payload) {
   state.iframetabData = state.iframetabData.filter(tab => tab.tag !== payload.tag)
  },
  [mainConst.M_Iframe_CHANGE_SELECTCODE] (state, payload) {
   state.iframeSelectTab=payload
  },
  // 设置全局system变量
  [mainConst.M_SET_SYSTEMNAME] (state, payload) {
   state.systemName=payload
  }
 },
 actions: {
  // actions的最终功能是修改state，但是它不直接修改state，而是调用mutations
  // async [aboutConst.A_REQUEST_DATA]({dispatch,commit}) {
  //  commit(aboutMutations.REQUEST_LOADING)
  //  await service.getMovieListData('{"movieType":"in_theaters","pageIndex":2,"start":0,"count":10}')

还要添加一个没用的路由，因为我们的锚记还要发生变化


const systemNamePrefix = "iframe_"
import MainContainer from '@/containers/MainContainer.vue'
import IframeComponent from '@Iframe/containers/IframeComponent.vue'

export default [
 {
  path: '/iframe',
  component: MainContainer,
  children: [
   {path: ':tag', component: IframeComponent, meta: {requiresAuth: true, keepAlive: true}},
  ],
  meta: {requiresAuth: true}
 }
]

3. 思考点

虽然这样和iframe结合有点恶心，但是可以实现我们的思路

在这个功能的实现中我们用到了bus事件总线的广播和监听

其实这点我们是可以仔细思考的，因为大量的使用广播不可控，我们可以完全用vuex去实现，这点用了广播，确实偷懒了
广播并不是不推荐，而是要使用对场景，这点其实用广播确实不太好，不利于扩展，谁能猜出来会有哪些扩展？

大家不用关心具体的代码，如果你们遇到类似的问题，了解这个思路就可以了

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持考高分网。
