JQuery implements text expansion and contraction Effects

There is only one small area on the webpage, but the descriptive text is very long. The following script displays the long text.

When you click expand, the text is expanded, and the text is shrunk.

Originally, you can write with the toggle () that comes with jQuery. However, when I do not work, toggle uses the click + flag to do this.
