Use Jquery to add the selected style to the navigation bar of the current page or the page after the jump

After clicking a column in the navigation bar of the page, I learned how to add a special style to the selected column. There are two situations: one is to add a special style directly to the current page. When the page is refreshed or jumps to the next page, the style disappears. When you select a column in the page navigation bar, I have learned how to add a special style to the selected topic and I will make a summary. There are two situations: one is to add a special style directly to the current page. When the page is refreshed or jumps to the next page, the style disappears; another scenario is that the style is valid even after the page is refreshed.
