Switching back to the normal font is achieved by converting the content into plain text and then replacing the element content.

The core code is as follows:

$('#f-author').css('cursor','pointer');
$('#f-author').click(function(event){
  var $author = $(this);
  if(!$author.children().is('b')){//子元素没有b
    $author.wrapInner('<b></b>');//包含在$author里面
  }
  else{
    var text = $author.text(); //纯文本
    $author.text(text);
  }
});

The complete code is as follows:
