Vue project city selection page-search logic implementation (8-8)

Search logic implementation

Search for your city based on the characters you enter.

1. First pass the data needed by the search bar from the parent component.
   
2. Bind our input box
   
3. First set the data to an empty string, then listen to the bound keyword, and add a timer to it to limit the current. The basic idea is to traverse and load the string into the list if it is found
   
4. Traverse the list and display the searched cities.
   
5. A calculation attribute is set, and if the search fails, it will display "No matching data found"
