Superstar learning brush course browser - stable version

Online classes on each platform have corresponding tests. However, these tests are not so friendly to those students who adhere to the principle of happy learning first. In order to make these students enjoy the fun of high scores, we have found some small helpers to make online learning happier.

Supplement 2020-6-29: update the superstar test script to adapt to multi video courses. It solves the problem that multiple videos under the previous chapter cannot be played

Mending 2020-7-12: some netizens left a message saying that the double play can't be used. I didn't pay much attention before. Then I tried it myself. There is a problem. I'll try to see if it can be repaired in recent days. There are more things near the end of the term. I hope you can understand. Let's make do with it first
Supplement 2020-8-1: shared the code of skipping the discussion version
Supplement 2020-8-4: I don't know why the previous one written in jquery syntax will report an error after a period of time. It is simply changed to use the native javascript syntax

Official tutorial:

Built in course brushing plug-in, add the following code to realize automatic course brushing

Link: https://www.lanzoux.com/b01hkgoze

The effect is shown in the figure:

Step 1: view the description (key points)

Step 2: unzip the plug-in

Step 3: open the browser. The browser has its own course brushing script and examination script. There is no need to configure it manually.

Step 4: after clicking start answer, you can see the answer of the current chapter test on the web page.

The script code is as follows:
