                colSlider
            ]
        });

        colSlider.on({
            change: function (s, v) {
                g.setTimeColumnWidth(v, true);
            },
            changecomplete: function (s, v) {
                g.setTimeColumnWidth(v);
            }
        });
    }
};

在我的 html 文件中，我包含了 basic.js

我想从 basic.js 访问var taskStore，但很难。

我试着这样做：

var test = App.Gantt.taskStore;
var test = taskStore;

他们没有工作。

最简单也是最丑陋的方法是将其分配给窗口：window.taskStore = taskStore。然后任何文件都可以访问这个变量。花点时间考虑一下您的 JS 应用程序的设计并按照 Brian 的建议做会更好。谁应该知道taskStore等...

Usingvar意味着它是一个私有变量，不能在App.Gantt. 而是尝试使用将this.taskStore = ...其设置为成员变量App.Gantt并使其可公开访问的设置。
