JavaScript代码是否需要以“<！ - "开头？” [英] does javascript code need to start with "<!-- "?

问题描述

我是新手。

许多javascript代码都以<！ -

开头。

 < script type =text / javascript> 
 <！ -  
  

结束于 // - - >

  //  - > 
< / script> 
  

我认为原因在于兼容性。

但是我找不到线索在任何书籍中都是如此。

即使我找不到任何与Google有关的信息。 p>没有。这是Netscape 2普遍存在的原因。

今天任何可以在网络上运行的浏览器都不需要它，它对于XHTML。

我写了更长的解释去年。

I am newbie.

many of javascript code start with <!--

<script type="text/javascript">
        <!--

and finish with //-->

//-->
    </script>

I think the reason is for compatibility.
But I cannot find the clue in any books.

even I cannot find anything with google.

解决方案

No. This is a holdover from the days when Netscape 2 was common.

It isn't needed with any browser that can function on the web today, and it is positively harmful in XHTML.

I wrote a longer explanation last year.
