How to implement integrated Iframe page using Vue

This article mainly introduces examples of how Vue integrates Iframe pages. The editor thinks it is quite good. Now I will share it with you and give it as a reference. Let’s follow the editor and take a look.

1. Project requirements

We will switch to the vue framework later. Before, some functional pages used jsp pages. Written, and our management system needs to support both the Vue URL and the jsp pages after these releases

The other thing is that when switching tabs back, the previously entered things still exist

System page screenshot

2. Implementation idea

In response to this problem, our initial implementation idea was to write a Common components of iframe, and then pass the URLs of different http pages to switch, but this does not satisfy the second point. We found that as long as we switch the route of vue, and then switch back to the http page, the src attribute in the iframe The page will be refreshed, and there is no way to retain things, so we have the following implementation idea

We added an iframeTemp component at the same level as vue's router-view, which is actually a tab component of elementUI, and then Hide the style of the tab component header under our menu bar

<template>
 <!--路由渲染的功能模块区域-->
 <p class="router-out-content">
  <!--缓存部分页面的写法-->
  <keep-alive>
   <router-view v-show="!showIframe" class="position router-content" v-if="$route.meta.keepAlive"></router-view>
  </keep-alive>
  <router-view v-show="!showIframe" class="position router-content" v-if="!$route.meta.keepAlive"></router-view>
  <!--兼容系统外部页面-->
  <iframe-temp v-show="showIframe"></iframe-temp>
 </p>
</template>
<style scoped lang="scss">
 .position {
  position: relative
 }

 .router-out-content {
  position: static;
 }
</style>
<script>
import { mapState } from &#39;vuex&#39;
import iframeTemp from &#39;@/containers/main/IframeTemplate.vue&#39;
export default {
 data() {
  return {}
 },
 components: {
  iframeTemp
 },
 computed: {
  ...mapState([
   &#39;showIframe&#39;
  ])
 }
}
</script>

    // 2、如果删除的一级tab不是当前激活的一级tab，TabsTemeplate中的一级tab删除事件已经在vuex中删除了，不需要做路由跳转操作了
    let index = obj.index

    let url = `/${_this.systemName}`
    if (con) {
     // 还有其他的一级tab，就赋值其他的一级tab的url，探后跳转
     url = con.url
     con.active = true

     // 如果还有其他一级的tab,那么还要判断跳转的页面是不是iframe
     if (url.toLowerCase().indexOf("/iframe") == 0) {
      // 如果是iframe页面，显示iframe,广播iframe的切换tab切换事件，路由进行跳转
      _this.$store.commit(mainConst.M_SHOW_IFRAME)
      _this.$root.bus.$emit("changeIframeTab", url.slice(8))

     } else {
      // 如果不是iframe页面，隐藏iframe,路由进行跳转
      _this.$store.commit(mainConst.M_HIDE_IFRAME)
      // _this.$store.commit(mainConst.M_UPDATE_NAVTABDATA, {navIndex: index})
     }

     _this.$store.commit(mainConst.M_HIDE_IFRAME)
    }

The display, hiding and tab switching of the ifram component are all implemented by universal vuex and bus event broadcast

      menuList[i].active = false
     }
    }
    return childFuncs
   }
  }
 }
</script>

We also need to add a useless route because our anchor has to change

/*
 * iframe/router/index.js
 */
const systemNamePrefix = "iframe_"
import MainContainer from &#39;@/containers/MainContainer.vue&#39;
import IframeComponent from &#39;@Iframe/containers/IframeComponent.vue&#39;

export default [
 {
  path: &#39;/iframe&#39;,
  component: MainContainer,
  children: [
   {path: &#39;:tag&#39;, component: IframeComponent, meta: {requiresAuth: true, keepAlive: true}},
  ],
  meta: {requiresAuth: true}
 }
]

/*
 * iframeComponent.vue，一个没用的vue文件，只是为了让浏览器中的锚记发生变化
 */

<template>
 <p v-if="isCache">
  <span>{{src}}</span>
 </p>
</template>
<style scoped lang="scss">
</style>
<script>
 export default{
  data(){
   return {
    isCache: true,
    src: &#39;&#39;
   }
  },
  created(){
  },
  mounted(){
   // 1、这个页面存在的意义就是在iframe页面切换的时候，路由可以跳转过去用，没有实际大的作用，但是得有这个页面
   // 2、iframe的Tab页面的z-index比这个页面的高
   this.src=this.$route.params.tag
  }
 }
</script>

3. Thoughts

Although it is a bit disgusting to combine it with iframe, it can realize our idea

In the implementation of this function, we use the broadcast and monitoring of the bus event bus

In fact, we can think about this carefully, because the large-scale use of broadcasts is uncontrollable. We can completely use vuex to achieve this. Using broadcasts is indeed lazy
Broadcasting is not not recommended, but it must be used in the right scenario. In fact, using broadcasting is not very good and is not conducive to expansion. Who can guess what expansions there will be?

You don’t need to care about the specific code. If you encounter similar problems, just understand this idea.

The above is what I compiled for everyone. I hope that I will use it in the future. Helpful to everyone.

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
