sliderToggle does not take effect when writing jquery timer setTimeouter_jquery

Today when I was writing jquery, I found that sliderToggle did not take effect in setTimeouter, and an error was reported saying that an unexpected error occurred. After looking at it for a long time, I didn’t understand it. Then I suddenly discovered that just use show();hide();.

Some study notes of bootstrap.

First of all, you should understand its frame structure and what corresponds to what. Secondly, you should be proficient in memorizing the names. Generally speaking, what you see is what you get, and the names are very regular. The last thing is to practice more and gradually master these rules during practice.
