javascript中还需要吗？它是用来干什么的？
谢谢
不再需要它了。它被用来在不理解<；脚本>标签。自90年代中期以来制造的每一款浏览器都理解Javascript，即使出于某种原因它不支持它。这将是//<--和//-->。排在前面的//注释代表理解Javascript的浏览器。不理解Javascript的浏览器会看到HTML注释（<；！---->；）中包装的script标记体，因此他们仍然不会将其呈现为纯文本。
它只适用于Netscape 1和Mosaic。
Do not use the
<!-- //-->hack with scripts. It was intended to prevent scripts from showing up as text on the first generation browsers Netscape 1 and Mosaic.
它并不需要。。。基本上永远。
我相信它是用来确保不理解javascript的浏览器不会将其显示为文本。将渲染超旧的浏览器
<script type="text/javascript">
var something = 0;
</script>
就像现代浏览器一样
<span>
var something = 0;
</span>
当然，它被呈现为文本。开头/结尾的注释告诉浏览器将内容视为HTML注释。现代浏览器知道要忽略这些。
