How to implement scenic spot navigation and travel guide in uniapp

With the rapid development of tourism, more and more people like to travel to various places. Sometimes when traveling in a strange city, we may get lost and don't know where to go to see the scenery or find delicious restaurants. In order to help tourists better navigate attractions and provide travel strategies, we can use uniapp to develop a powerful application.

1. Navigation function implementation

1. Obtaining geographical location information
   In uniapp, you can use the uni.getLocation API to obtain the user's geographical location information. For example, the API can be called when the "Navigation" button is clicked to obtain the user's current latitude and longitude information.
2. Map display
   You can use plug-ins, components or APIs to implement map display functions in uniapp, such as uni-ui, uview-ui, etc. You can add a map component to the page and set the center location of the map to the user's current latitude and longitude, as well as the appropriate zoom level.
3. Add marker points
   In order to display the location of attractions, you can use the API of the map component to add marker points. You can obtain the latitude and longitude of the scenic spot from the background interface, then add a marker point on the map, and set the icon and click event of the marker point.
4. Route planning
   If the user wants to know how to get to a certain attraction from the current location, he can use the API of the map component for route planning. The API can be called when clicking on an attraction marker, passing the user's current location and destination to the map component, and then the map will automatically plan the best route and display it on the map.

2. Travel strategy implementation

1. Database storage
   In order to realize the travel strategy function, it is necessary to store attraction information, restaurant information, travel schedule and other data in the database . You can use the database API provided by uniapp to create database tables and store related data.
2. Data display
   You can use the list components, card components, etc. provided by uniapp to display travel strategy data. The data can be read from the database, sorted, filtered, etc. based on requirements, and then the processed data can be displayed on the page.
3. Search function
   In order to facilitate users to find travel guides, the search function can be implemented. You can use text input components and button components to implement search boxes and search buttons, and then use the database API to query matching data and display the results.
4. User comments and likes
   In order to increase interactivity and user participation, you can add comments and likes functions to each travel guide. You can use the database API to implement user comments and likes functions, and display the number of comments and likes on the page.

The above are some basic ideas and code examples for implementing attraction navigation and travel strategies in uniapp. Of course, the specific implementation methods and functional details still need to be adjusted and improved according to actual needs. I hope this article is helpful to you, and I wish you smooth development!
