Using JavaScript and Tencent Maps to implement map street view navigation function

Overview:
With the rapid development of the Internet and smart phones, map navigation has become a way for people to travel. A must-have tool. Tencent Maps is an excellent map navigation application in China. It not only provides common 2D maps, satellite maps and other functions, but also provides powerful street view navigation functions. This article will introduce how to use JavaScript and Tencent Map API to implement map street view navigation.

Steps:

1. Obtain Tencent Map API key
   Register an account on the Tencent Map open platform and apply for an API key.

2. Introduce Tencent Map API
   Import the JavaScript file of Tencent Map API in the HTML file, for example:

   <script src="https://map.qq.com/api/js?v=2.exp&key=YOUR_API_KEY"></script>

3. Create a map container
   In Add a <div> element for displaying the map in the HTML file, for example: <pre class='brush:html;toolbar:false;'>&lt;div id=&quot;map&quot; style=&quot;width: 100%; height: 500px;&quot;&gt;&lt;/div&gt;</pre><li> <p>Initialize the map<br>In the JavaScript code, use the API to provide The <code>QQMapAPI.createMap() function initializes the map and specifies the map container and map initial configuration, for example:

   var map = new qq.maps.Map(document.getElementById('map'), {
     center: new qq.maps.LatLng(30.25, 120.17),
     zoom: 18
   });

4. Add Street View navigation control
   After initializing the map After that, use the qq.maps.OverviewMapControl() function provided by the API to add the Street View navigation control, for example:

   var svControl = new qq.maps.StreetViewControl();
   map.controls[qq.maps.ControlPosition.TOP_RIGHT].push(svControl);

5. Add the Street View navigation event listener
   When When the user clicks on the Street View navigation control, we can monitor the event and handle it accordingly. For example, when the user clicks to enter the Street View navigation mode, we can switch to the Street View navigation view and load the corresponding Street View data, for example:

   qq.maps.event.addListener(svControl, 'status_changed', function() {
     if (svControl.getStatus() === qq.maps.StreetViewControlStatus.FULL) {
       // 切换到街景导航视图
       map.setStreetView(new qq.maps.StreetViewPanorama(document.getElementById('map')));
       // 加载街景数据
       map.getStreetView().setVisible(true);
     }
   });

6. Other function customization
   According to needs, you can also use the API The methods provided are used to customize functions such as changing the street view perspective and switching street view navigation.

Summary:
This article introduces how to use JavaScript and Tencent Maps to implement the map street view navigation function. By using the Tencent Map API, we can easily implement the map street view navigation function in the web page and customize the corresponding functions. I hope this article can help readers understand how to use Tencent Map API to implement map street view navigation functions, and conduct corresponding development and customization based on actual needs.
