How to use JS and Amap to realize the location street view display function

In modern web development, the map function has become a very common requirement. In the map, the street view display function can more realistically display the actual situation of the location and provide users with a more intuitive experience. This article will introduce how to use JavaScript and Amap API to implement the function of displaying location street views, and give specific code examples.

1. Introducing the Amap API

First of all, we need to introduce the Amap API into the web page. You can load the JS file of Gaode Map by introducing the following code in HTML:

<script src="https://webapi.amap.com/maps?v=1.4.15&key=YOUR_API_KEY"></script>

In the above code, you need to replace YOUR_API_KEY with your own Gaode Map API key . If you have not registered an Amap developer account, you can go to the Amap open platform to register and obtain an API key.

2. Create a map object

After introducing the Amap API, we need to create a map object for displaying maps and street views.

// 创建地图对象
var map = new AMap.Map('map-container', {
  zoom: 16,
  center: [116.397428, 39.90923]
});

In the above code, map-container is the ID of a container used to display the map. zoom represents the zoom level of the map, center represents the center point position of the map. The coordinates here [116.397428, 39.90923] are the latitude and longitude of Tiananmen Square in Beijing.

3. Create Street View Object

Next, we need to create a Street View object to display the Street View information of the location.

// 创建街景对象
var panorama = new AMap.Panorama('panorama-container');

In the above code, panorama-container is the ID of a container used to display street view.

4. Set location coordinates

After creating the Street View object, we need to set the latitude and longitude coordinates of the location to be displayed.

// 设置地点坐标
var position = [116.397798, 39.908434];
panorama.setPosition(position);

In the above code, position represents the latitude and longitude coordinates of the location to be displayed. The coordinates here [116.397798, 39.908434] are the street view coordinates of Tiananmen Square in Beijing.

5. Listening to map click events

In order to allow users to click on locations on the map to display street views, we need to listen to map click events.

// 监听地图点击事件
map.on('click', function(e) {
  var position = e.lnglat;
  panorama.setPosition(position);
});

In the above code, e.lnglat represents the latitude and longitude coordinates of the location clicked by the user. When the user clicks on a location on the map, we pass the coordinates of the location to the Street View object to display the Street View information of the corresponding location.

Through the above steps, we can realize the function of displaying location street view on the web page. Users can click on a location on the map or directly set the coordinates of the location to display the street view information of the corresponding location.

Summary:

This article introduces how to use JavaScript and Amap API to implement the function of displaying location street views, and gives specific code examples. Through the above methods, developers can easily integrate map and street view functions into web pages to provide users with a more intuitive display of geographical information. Of course, developers can also expand and optimize the code according to needs to achieve richer and more personalized map functions.
