jQuery无法识别前缀为“/”的类名

I have the following html code:

我有以下HTML代码:

   <div class="/temp">asdf</div>
   <input type="button" class="hide_message_button" value="Hide">

And the jQuery for it is something like this:

而jQuery就是这样的:

$('.hide_message_button').click(function(){
   var bool = $('./temp').is(':hidden');
   if(bool){
      $('./temp').show();
      $(this).val('Hide');
   }
   else {
      $('./temp').hide();
      $(this).val('Show');
   }
});

Well all I am trying to do is show or hide the div on button click. However, I get the following error:

好吧,我要做的就是在按钮点击时显示或隐藏div。但是,我收到以下错误:

Uncaught Error: Syntax error, unrecognized expression: ./temp

Works fine when the class name is just "temp". Unfortunately, the class name is prefixed with / and I would not like to change it. How do I resolve the error?

当类名只是“临时”时工作正常。不幸的是,类名前缀为/,我不想改变它。我该如何解决这个错误?

You need to escape the meta-characters.

你需要逃避元字符。

To use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) as a literal part of a name, it must be escaped with with two backslashes: \\

要使用任何元字符(例如!“#$%&'()* +,。/:; <=>?@ [] ^`{|}〜)作为名称的文字部分,必须使用两个反斜杠进行转义:\\

$('.\\/temp').is(':hidden');
