In the new version of jquery, the live () method has been deleted, so we will prompt that the function does not exist when calling. js reports an error.

The solution is to use the on () function to replace,

The original statement is:
 
If you replace it with the on () method, the newly generated element does not have any effect when you click the event again. The new syntax is:
 
This involves a question: $ ("body") Why is the body here? In fact, we can choose other nodes closer to # company_logo, which will provide better performance. In fact, on () find the # company_logo node in the body, so we can replace it with the # company_logo superior node to achieve better performance.
