1.引入资源创建地图
//index.html
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>智慧校园</title><!-- 引⼊资源 --><!-- css样式 --><link rel="stylesheet" href="https://a.amap.com/jsapi_demos/static/demo-center/css/demo-center.css" /><link rel="stylesheet" href="./css/index.css"><!-- 引⼊js资源 --><script type="text/javascript">window._AMapSecurityConfig = {securityJsCode: 'code',}</script><script type="text/javascript" src="https://webapi.amap.com/maps?v=2.0&key=key"></script>
</head>
<body><!-- 创建地图容器 --><div id="container"></div><script>//创建地图对象var map = new AMap.Map('container', {center: [114.402672, 30.518987],zoom: 16,viewMode: '3D',pitch: 45,})</script>
</body>
</html>
//css/index.css
html,
body,
#container {width: 100%;height: 100%;
}
2.使用控件
// 使⽤控件AMap.plugin(['AMap.ToolBar', 'AMap.Scale', 'AMap.ControlBar'], function () {map.addControl(new AMap.ToolBar())map.addControl(new AMap.Scale())map.addControl(new AMap.ControlBar())})
3.标记功能
右上⻆就有了交互控件,且可以⽤⿏标左键单击添加标记。
//使⽤⾼德的css样式来创建⼀个div控件<div class="info">点击地图标注热⻔地点</div>
// 添加监听地图点击事件map.on('click',function(e){// 创建标记var marker = new AMap.Marker({position:e.lnglat,})// 添加标记图层map.add(marker)})
4.使⽤GeoJSON数据持久化
使⽤GeoJSON在本地存储中记录数据
首页我们需要创建一个store.js文件用来写读取和存入的函数
// 从local storage中读取数据
function getData() {//判断本地local storage中不存在数据if (!localStorage.getItem('geojson')) {localStorage.setItem('geojson', '[]')}return JSON.parse(localStorage.getItem('geojson'))
}
// 从local storage中写数据
function saveData(data) {localStorage.setItem('geojson', JSON.stringify(data))
}
在index .html引入
<script src="./js/store.js"></script>

</body>
</html>
5.实现打卡
实现思路:使用marker覆盖物的点击事件,导入数据的地方恢复旧数据的点击事件
