How to use JS and Baidu Maps to implement the map street view function

The map street view function is a perspective on the map that allows users to enjoy street view photos on the electronic map experience. Baidu Maps provides a powerful API that allows us to simply use JavaScript to implement this function. The following will introduce in detail how to use JS code and Baidu Map API to implement the map street view function.

Step one: Prepare the development environment for Baidu Map API
First, you need to introduce Baidu Map API into your HTML file. Use the following code:

<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的百度地图API密钥"></script>

Among them, you need to replace "your Baidu Map API key" with the API key you applied for on the Baidu Map Developer Platform.

Step 2: Create a map container
Create a container in the HTML file to display the map and street view. Use the following code:

<div id="map"></div>

Step 3: Initialize the map
Use JavaScript code to initialize the map. Use the following code in your JavaScript file:

var map = new BMap.Map("map");
map.centerAndZoom(new BMap.Point(116.404, 39.915), 11); // 设置地图中心点
map.enableScrollWheelZoom(); // 启用缩放功能

This code will create a map object and display it in a div container with the id "map". The center point of the map is set to coordinates (116.404, 39.915), the zoom level is 11, and the wheel zoom feature is enabled.

Step 4: Add map street view
Add the following code in the Javascript file to add map street view:

var panorama = new BMap.Panorama('map');
panorama.setPosition(new BMap.Point(116.404, 39.915)); // 设置街景位置
panorama.setPov({heading: -40, pitch: 6}); // 设置街景视角
panorama.show(); // 显示街景

This code first creates a street view object and displays it in the id In the div container of "map". Then, set the street view's position to coordinates (116.404, 39.915), the viewing angle to heading to -40, and pitch to 6. Finally, the street view is displayed by calling the show() method.

So far, you have successfully implemented the map street view function. You can adjust the initial position of the map and the position and perspective of Street View to suit your needs.

The following is a complete JavaScript code example:

// 初始化地图
var map = new BMap.Map("map");
map.centerAndZoom(new BMap.Point(116.404, 39.915), 11); 
map.enableScrollWheelZoom(); 

// 添加地图街景
var panorama = new BMap.Panorama('map');
panorama.setPosition(new BMap.Point(116.404, 39.915)); 
panorama.setPov({heading: -40, pitch: 6}); 
panorama.show(); 

Please make sure to replace your own API key and coordinate values ​​when using the above code.

Summary:
By using Baidu Map API and JavaScript, we can easily implement the map street view function. First, introduce Baidu Map API into the HTML file and create a map container. Then, initialize the map and street view in a JavaScript file, and set the location and perspective. Finally, the map and street view are displayed. With subtle adjustments and customization, you can create a variety of map street view features based on your needs.
