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>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

zoom: 16,
viewMode: '3D',
pitch: 45,
})
// 使⽤控件
AMap.plugin(['AMap.ToolBar', 'AMap.Scale', 'AMap.ControlBar','AMap.GeoJSON'], function () {
map.addControl(new AMap.ToolBar())
map.addControl(new AMap.Scale())
map.addControl(new AMap.ControlBar())
})
//定义全局变量
var geojson = new AMap.GeoJSON({
geoJSON: null,
})
// 导⼊数据
if (JSON.stringify(getData()) != '[]') {
//有数据的时候才导⼊
geojson.importData(getData())
}
map.add(geojson)
// 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,
})
// 通过geojson对象管理覆盖物
geojson.addOverlay(marker)
//console.log(geojson)
saveData(geojson.toGeoJSON())
})
</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文章来源:https://www.toymoban.com/news/detail-859006.html
