中国地图
- 实现效果图
- 创建echartChina.vue组件
- 使用echartChina.vue组件
- 修改标记图标为图片
实现效果图
这是一个有阴影的,并且根据坐标点被标记的地图展示，下面我们就把实现的代码贴出来，老样子，还是开袋即食！
创建echartChina.vue组件
1.点击下载中国地图json文件
把中国地图的json数据下载下来，放到项目本地中的utils文件夹下；位置随意，想放哪里都可以，能找到就行！
2.先写一个echartChina.vue组件
为了方便复用，我们可以先写一个地图组件，因为要实现地图阴影的效果，所以组件中对地图渲染了两次进行重叠，第一次是初始化地图阴影，第二次初始化就是实现地图功能效果的；
组件全部代码如下，直接粘贴即可；
<template>
<div id="china_map"></div>
</template>
<script>
import * as echarts from 'echarts';
import china from '@/utils/china.json'
echarts.registerMap('china', china)
export default {
data() {
return {

//初始化中国地图
initEchartMap() {
let mapDiv = document.getElementById('china_map');
let myChart = echarts.init(mapDiv);

使用echartChina.vue组件
在需要使用地图的组件，直接引入即可，然后把需要展示的坐标地点传给地图组件，全部代码如下：
<template>
<div class="echartChina">
<EchartChina ref="myEchart4"/>
</div>
</template>
<script>
