Reason: When HTML renders the page, multiple spaces or line breaks will be merged into one space and displayed on the page
Solution:
You can use the <pre></pre> tag when rendering the page and insert the returned string into this tag.
pre 标签可定义预格式化的文本。被包围在 pre 标签中的文本通常会保留空格和换行符。而文本也会呈现为等宽字体
Use "<br/>" tag to replace line

Uh-huh. . The webpage does not recognize n.
split("n") gets the new array, and then generates a new tag with <br/> insert it into a new line
