返回和换行符?

2022-01-19 00:00:00 return javascript

我今天搞砸了一些事情，我要返回一个 DOM 树.我想知道是否有办法让代码如下:

I was messing around with something today, where I'm returning a DOM tree. I was wondering if there was a way to have the code be like:

return
  '<div id="something"> 
     <p>Stuff</p> 
   </div>'

代替:

return '<div id="something"> 
     <p>Stuff</p> 
   </div>'

只是出于美学原因 - 第一个看起来更好.我在 Google 上搜索了大约 10 分钟，然后想我应该问问那些比我了解更多的人.

just for aesthetic reasons - the first one looks better. I Googled it for about 10 minutes, then figured I ought to just ask those who know more than me.

推荐答案

不，不是.

return后的新行触发分号插入，所以代码相当于:

A new line after a return triggers semi-colon insertion, so the code is equivalent to:

return;
  '<div id="something"> 
     <p>Stuff</p> 
   </div>';

…然后你返回 undefined.
