Vue

  • definition

    • Vue is a front-end framework that can eliminate DOM operations in native JavaScript and simplify writing

      • The MyBatis framework we learned before is used to simplify JDBC code writing; Vue is a front-end framework that simplifies JavaScript code writing.

      • Added Axios and JSON comprehensive caseThere are a lot of DOM operations in , the examples are as follows:

        let brandName = document.getElementById("brandName").value;
        let companyName = document.getElementById("companyName").value;
        let ordered = document.getElementById("ordered").value;
        let description = document.getElementById("description").value;
        // 获取单选框数组
        let status = document.getElementsByName("status");
        //2.3 给JS对象设置数据
        formData.brandName = brandName;
        formData.companyName = companyName;
        formData.ordered = ordered;
        formData.description = description;

    • It is based on the MVVM (Model-View-ViewModel) idea, which can realize dataTwo-way binding , focusing programming on data

      • Note: The MVC pattern learned before can only realize one-way display from model to view, and cannot bind the view and model to each other (that is, as long as one of the model and view changes, the other will also change)

Vue Quick Start

  • Create a new Html page and import itVue.jsdocument

    • If you import local Vue files (the blogger uses the last version of VUE2:Vue2.7.16开发环境, you can go to the official website to download the correspondingjsdocument)

      <script src="js/vue.js" type="text/javascript" charset="UTF-8"></script>

  • In the JS code area (in<Script>tag body), create Vue core objects for data binding

    • When creating a Vue object, you need to pass a js object, which requires the following properties:

      Attributesexplain
      elSpecifies which tags are managed by Vue. #app middleapp For tags managed by VueidProperty Value
      dataUsed to define data types
      methodsUsed to define functions, you can return the function value through return
      new Vue({
          el:"#app",
          data() {
              return {
                  username : ""

Vue Lifecycle

  • The Vue life cycle has eight stages

    • Each time a life cycle event is triggered, aLifecycle methods (Also called hook method)
  • The following is the position of each life cycle

  • mounted: Mounting completed, Vue initialized successfully, Html page rendered successfully

    • We can send an asynchronous request in this method to load data

    • Simple Example

      new Vue({
          el:"#app",
          mounted() {
            alert("Vue挂载完毕,发送异步请求")

  • question

    • why wouldvar _this = thisWhy not directlythis.brands=resp.data

      In JavaScript this The behavior of a keyword depends on the context in which it is called. In a Vue instance method,this Points to the Vue instance itself. But in Axiosthen In the callback function of the method,this May point to some other object, usually the global object (window object). This will prevent you from correctly accessing the properties and methods of the Vue instance.

      By definition var _this = this, you will Vue instance this save at_this variable, and then use it in the callback function_this To correctly reference the Vue instance.

Element

  • definition

    • It is a set of Vue-based website component libraries that can be used to quickly build web pages
    • Components: the parts that make up a web page, such as hyperlinks, buttons, pictures, tables, etc.

Element Quick Start

  • Step1: Import Vue.js file

  • Step2: Willelement-uiPut the directory in the core directory of the Web project (ie webapp), and then introduceelement-uicss, js files

    • Import local Element's css and js files

      <!-- 引入样式 -->
      <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css">
      <!-- 引入组件库 -->
      <script src="element-ui/lib/index.js"></script>

    • Import css and js files of remote Element

      <!-- 引入样式 -->
      <link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
      <!-- 引入组件库 -->

  • Step3: Create Vue core objects (see Vue section for details)

  • Step4: ElementOfficial WebsiteCopy the Element component code

  • The basic HTML page structure code is as follows:

    <!DOCTYPE html>
    <html lang="en">
        <head>
            <meta charset="UTF-8">
            <title>Title</title>
        </head>
        <body>
            <div id="app">
                <!--3 从官网复制自己想要的组件代码并做对应设计更改-->
                
            </div>
    
            <!--1 引入vue.js文件、element的index.css文件和index.js文件-->
            <script src="js/vue.js" type="text/javascript" charset="UTF-8"></script>
            <!-- 引入样式 -->
            <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css">
            <!-- 引入组件库 -->
            <script src="element-ui/lib/index.js"></script>
    
            <!--2 创建Vue核心对象-->
            <script>
                new Vue({
                    el : "#app"
                })

  • Step5: Add checkboxes to the table: Find the table with checkboxes and copy the code for the checkboxes.

    • Since the check box can be selected in the case diagram to perform batch operations on the row of data, the table must have a method, so when we copy the code about the check box, we must also copy the corresponding method in the table with the check box (don't forget to write the method in the Vue core object), the method is as follows

      handleSelectionChange(val) {
          this.multipleSelection = val;
      }
      
      • 1
      • 2
      • 3

      This method has a propertymultipleSelection, so we need to copy this property into our own code. The final complete code is as follows:
