How to use vue region selection component

This time I will show you how to use vue region selection components. What are the precautions for using vue region selection components? . The following is a practical case, let's take a look.

Overview

is mainly used for the operation of regional data across the country, including linkage at the provincial, municipal and district levels, the addition and deletion of regional data ; When operating regional data, we have used tree-shaped region selection components before, but because the rendering was slow when operating a large amount of regional data, we changed to another data display form and interaction form, thus achieving With this component.

Note: This component is a vue.js component

Parameters
The area selected in the component

Props

area

area parameter is required and represents the region data when the component is initialized. It can be empty. area is an array containing multiple objects. The data structure of each object is as follows:

...
area: [
 {Name: '北京', ID: '01'},
 {Name: '南京', ID: '0401'},
 {Name: '西湖区', ID: '060105'}
],
...

Because later in actual use, I found that sometimes, the background only returns one area. ID value, so optimization has been done here, you can only pass in the ID value, for example:

...
area: [
 {ID: '01'},
 {ID: '0401'},
 {ID: '060105'}
],
...

selected

selected is an event published internally by the component , you can subscribe to this event outside the component to get the value it returns. This value is all the areas currently selected by the component. The returned value is an array composed of multiple objects containing area data, data structure and area parameters. Same as

Simple example

<p>
  <addressmap :area="area" @selected="selected"></addressmap>
</p>

Install

and use

npm install adc -addressmap

If used as a global component<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">//在项目入口文件 import Vue from 'vue' import Addressmap from 'adc-addressmap' Vue.component('Addressmap', Addressmap) 若作为局部组件 //在某个组件中 import Addressmap from 'adc-addressmap' export default { ...  components: { Addressmap}, ... }</pre><div class="contentsignin">Copy after login</div></div> I believe you have mastered the method after reading the case in this article.
