Both plug-ins implement web page loading progress bars, and there are four default methods:
start(): Start the progress bar
set(num): maximum progress, default 0 to 1
inc(): Increase the speed. When the progress bar starts, this function can be used.
done(): The progress bar runs directly to completion
