javascript中的三个斜杠有什么作用？ [英] What does the three slashes in javascript do?

问题描述

我还是Javascript的新手，所以当我的编辑突出显示它时，我很感兴趣。它到底是做什么用的？

I'm still new to Javascript so when my editor highlights it I'm intrigued. what exactly does it do?

示例： ///事后要去的地方

推荐答案

一些文档生成器将三个斜杠///视为向JavaScript引入文档注释。

Some documentation generators regard three slashes /// as introducing documentation comments to JavaScript.

因此，就JavaScript而言，三个斜杠的工作方式与两个斜杠相同（它是一个注释到行尾），但文档生成器可以解释三个斜杠来指示文档部分。

So three slashes work the same as two slashes as far as JavaScript is concerned (it's a comment-to-end-of-line), but three slashes can be interpreted by documentation generators to indicate a documentation section.

示例：

  function getArea(radius)
  {
      /// <summary>Determines the area of a circle that has the specified radius parameter.</summary>
      /// <param name="radius" type="Number">The radius of the circle.</param>
      /// <returns type="Number">The area.</returns>
      var areaVal;
      areaVal = Math.PI * radius * radius;
      return areaVal;
  }
