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

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:
| Attributes | explain |
|---|---|
el | Specifies which tags are managed by Vue. #app middleapp For tags managed by VueidProperty Value |
data | Used to define data types |
methods | Used to define functions, you can return the function value through return |
new Vue({
el:"#app",
data() {
return {
username : ""
}
}
});

The Vue life cycle has eight stages
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({

}
});

The screenshot after Tomcat runs the Web project is as follows
question
why wouldvar _this = thisWhy not directlythis.brands=resp.data
In JavaScript
thisThe behavior of a keyword depends on the context in which it is called. In a Vue instance method,thisPoints to the Vue instance itself. But in AxiosthenIn the callback function of the method,thisMay point to some other object, usually the global object (windowobject). This will prevent you from correctly accessing the properties and methods of the Vue instance.By definition
var _this = this, you will Vue instancethissave at_thisvariable, and then use it in the callback function_thisTo correctly reference the Vue instance.

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 -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
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>

Explanation: It will provide many rows, each row has 24 basic grids
step:
Step 1: Import vue.js file, element's index.css file and index.js file
Step 2: Create Vue core objects
Step 3: Copy the component code you want from the official website
<style>The tag body contains CSS style code, which can be imported externally or written directly into the HTML page.<el-row>

Open the html page through the browser, the screenshot is as follows
Definition: A container component used for layout, which facilitates and quickly builds the basic structure of the page
Explanation: As shown in the figure above, it is a layout with a left navigation bar
step:
Step 1: Import vue.js file, element's index.css file and index.js file
Step 2: Create Vue core objects
Step 3: Copy the component code you want from the official website
Take the first instance as an example, as shown in the official website diagram
In this example, in addition to HTML and CSS codes, there are also properties of the Vue object, as follows
<script>
//export default为自己创建的Vue对象
export default {
data() {
const item = {
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄'
};
return {
tableData: Array(20).fill(item)
}
}
};
</script>
We can copy the properties of Vue in the official website instance to our own Vue core object, as follows
<script>
new Vue({
el : "#app",
data() {
const item = {
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄'
};
return {
tableData: Array(20).fill(item)
}
}
})
</script>

Open the html page through the browser, the screenshot is as follows
Make the effect as shown below

When the browser opens the HTML page, as shown in the figure, you can start to adjust it after getting the general picture.
Step2： Add columns and data to the table obtained in Step 1 and modify the column names
DeletewidthEach column will automatically adjust its width after the attribute
Center the table content: Scroll down the corresponding table component section on the official website to find the corresponding methods and properties, as shown in the figure.align="center"

}

})

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

Add the checkbox method to output and test whether it is successful. The code is as follows
handleSelectionChange(val) {
this.multipleSelection = val;
console.log(this.multipleSelection)
}
After the browser opens the page, open the developer tools → select the Console controller to view the output, as shown in the figure
Step6： Add a form: The form in the example diagram is horizontal, so we find a similar form (i.e. inline form) on the official website and copy the code. The code is as follows
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
