最近在做一个车辆管理系统，需要将车辆的定位轨迹通过高德地图回放出来。查找了一些文档后成功完成。
一、首先
在index.html中引入高德地图api
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<!-- <meta name="viewport" content="width=device-width,initial-scale=1.0"> -->
<!-- 禁止页面缩放 -->
<meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" name="viewport" />
<title>啊啊啊啊</title>
<!-- 企业微信api -->
<script type="text/javascript" src="http://res.wx.qq.com/open/js/jweixin-1.2.0.js"></script>
<!-- 高德地图 -->
<script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.14&key=dsffsdfdsfsdfsdfdsf"></script>
<!-- 调试工具 -->
<script src="https://cdn.bootcss.com/vConsole/3.3.4/vconsole.min.js"></script>
</head>
<body>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
其中的key需要你去高德地图注册获取，这里就不详细说了，度娘一查便知。
二、页面中使用
在trackquery.vue中去使用。在html中先设置一个id为"container"的容器
<template>
<div class="trackquery">
<div id="container" class="map"></div>
<div class="contbtn" v-if="lineArr.length > 0">
<flexbox>
<flexbox-item><div class="flex-demo">
<x-button v-if="starshow" class="btncol" type="primary" @click.native="starmove">开始动画</x-button>
<x-button v-if="!starshow" class="btncol" type="primary" @click.native="stopAnimation">停止动画</x-button>
</div></flexbox-item>
<flexbox-item><div class="flex-demo">
<x-button :disabled="btndisabled" v-if="endshow" class="btncol" type="primary" @click.native="endmove" style="background-color: rgb(68, 138, 202);">暂停动画</x-button>
<x-button :disabled="btndisabled" v-if="!endshow" class="btncol" type="primary" @click.native="resumeAnimation" style="background-color: rgb(68, 138, 202);">继续动画</x-button>
</div></flexbox-item>
</flexbox>
</div>
</div>
</template>
应为有可能在定位的时间段中会有多条数据，这里就需要后端去做一些判断，将数据分离出来。
然后在下面的js中去实现逻辑，多余的不说了，看代码
data() {
return {
btndisabled: true,
loadshow: false,
loadtext: '提交中',
showtop: true,
starshow: true,
endshow: true,

this.$axios.get('fsdsfdsf', dataobj)
.then(res => {
this.loadshow = false
res = JSON.parse(res)
// console.log(res)
if(res.Data.Statu_Code == 200) {
if(res.Data.List == null || res.Data.List == []) {
this.lineArr = []
this.$vux.toast.show({
text: res.Data.Msg,

完成，轨迹回放也没问题。
