Baidu Map provides various client calling methods such as sdk, javascript api, etc. It is commonly used on web pages, that is, javascript api. Here is a brief introduction to how to quickly use javascript to call Baidu map api according to your own use. Using Baidu map api, unlike other front-end frameworks, we can get a js library file on the official website, and then add it to the page by <script src = "path / to / lib.js"> </ script> The use of Baidu map api requires us to register as a developer, and then obtain something similar to the private key, and then use it on the page. Without the private key, we cannot call the map api.
