Pay attention to the following two points:

1. The jquery. js path should be correct, otherwise it will be difficult to achieve the desired effect.

2. You need to use $ (document ). ready, this method means that after the file is loaded, execute the JS script in it. If you do not add it, it may not be completed in your document organization, the event binding statement has been executed, but your "# load" has not been loaded yet, leading to event binding failure.
