Detailed explanation of SPA single page application in vue

This time I will bring you a detailed explanation of the SPA single-page application in vue. What are the precautions when using the SPA single-page application in vue. The following is a practical case. Let’s take a look. .

1. Overview of SPA

SPA (single page application) is a single page application. In a completed application or site, there is only one complete HTML page. This page has a container into which the code snippets that need to be loaded can be inserted.

How SPA works:

eg: http://127.0.0.1/index.html#/start

① Parse the complete page according to the url in the address bar: index.html
 Load index.html

②According to the routing address after url parsing # in the address bar: start
 According to the routing address, find the configuration object of the routing address in the current application configuration to find the The page address of the template corresponding to the routing address  Initiate an asynchronous request to load the page address

③Load the requested data into the specified container

2. Basic steps to implement a SPA through VueRouter

①Introduce the corresponding vue-router.js (I have uploaded this file to my file)

②Specify a container to hold code snippets

<router-view></router-view>

③Create various components required for the business

④Configure routing dictionary
Configuration object of each routing address (which page to load...)

const myRoutes = [
  {path:'/myLogin',component:TestLogin},
  {path:'/myRegister',component:TestRegister}
  ]
  const myRouter = new VueRouter({
  routes:myRoutes 
  })
  new Vue({
    router:myRouter 
  })

⑤Test

Enter the corresponding different routing addresses in the address bar to confirm whether the corresponding

    var testRegister = Vue.component("register",{

        <p>
          <h1>这是我的注册页面

    //配置路由词典
    //对象数组
    const  myRoutes =[
    //当路由地址：地址栏中的那个路径是myLogin访问组件
    //组件是作为标签来用的所以不能直接在component后面使用
    //要用返回值 
      //path:&#39;&#39;指定地址栏为空：默认为Login页面
        {path:&#39;&#39;,component:testLogin},
      {path:&#39;/myLogin&#39;,component:testLogin},
      {path:&#39;/myRegister&#39;,component:testRegister}
    ]
    const myRouter = new VueRouter({
      //myRoutes可以直接用上面的数组替换
      routes:myRoutes
    })
    new Vue({
      router:myRouter,
      //或者：

        router:new VueRouter({
            routes:[
              {path:&#39;/myLogin&#39;,component:testLogin},
      {path:&#39;/myRegister&#39;,component:testRegister}
            ]

    需要大家创建一个SPA，这个SPA有3个组件，分别对应的是collect/detail/order

    1、引入js文件
    2、创建三个组件,需要返回值
