Question

编译以下代码以生成带有JSDoc 3的文档时出错。如果我删除第一行“user strict”;然后它就可以了。这是JSDoc中的错误，还是我遗漏了什么？

代码：

"use strict";

var BaseClass = require("./BaseClass").BaseClass;

/**
 * @class
 * @extends BaseClass
  */
 var MyClass = BaseClass.extend(
 /** @lends MyClass.prototype */
 {
     /**
      * Initializer.
      * @public
      */
     initialize:function () {
         this._id = -1;
     },

     /**
      * Property id
      * @public
      * @property {number} id
      */
     get id() {
         return this._id;
     },

     set id(id) {
         this._id = id;
     }
 }); 

 exports.MyClass = MyClass;

这是我看到的错误：

如上所述，此语法在JavaScript的严格模式下是合法的。我怀疑这是JSDoc使用的Mozilla Rhino版本中的解析器错误。

作为一种变通方法，您可以使用以下插件在JSDoc分析文件之前注释掉“use strict”声明：

exports.handlers = {
    beforeParse: function(e) {
        e.source = e.source.replace(/['"]use strict['"]/g, "//'use strict'");
    }
};

JSDoc 3在严格模式下使用相同的名称解析错误getter / setter
