【问题描述】：

所以我在练习，当我点击它时它会运行，但是当我将它复制并粘贴到我自己的文字处理器 (Atom) 并在选项卡中运行它时，它只是空白

require([
"dijit/MenuBar",
"dijit/PopupMenuBarItem",
"dijit/Menu",
"dijit/MenuItem",
"dijit/DropDownMenu",
"dojo/domReady!"
], function(MenuBar, PopupMenuBarItem, Menu, MenuItem, DropDownMenu){
var pMenuBar = new MenuBar({});
var pSubMenu = new DropDownMenu({});
pSubMenu.addChild(new MenuItem({
    label: "File item #1"
}));
pSubMenu.addChild(new MenuItem({
    label: "File item #2"
}));
pMenuBar.addChild(new PopupMenuBarItem({
    label: "File",
    popup: pSubMenu
}));
var pSubMenu2 = new DropDownMenu({});
pSubMenu2.addChild(new MenuItem({
    label: "Cut",
    iconClass: "dijitEditorIcon dijitEditorIconCut"
}));
pSubMenu2.addChild(new MenuItem({
    label: "Copy",
    iconClass: "dijitEditorIcon dijitEditorIconCopy"
}));
pSubMenu2.addChild(new MenuItem({
    label: "Paste",
    iconClass: "dijitEditorIcon dijitEditorIconPaste"
}));
pMenuBar.addChild(new PopupMenuBarItem({
    label: "Edit",
    popup: pSubMenu2
}));
pMenuBar.placeAt("wrapper");
pMenuBar.startup();
});
</script>
<div id="wrapper"></div>

反斜杠是句点没有问题。

【问题讨论】：

在执行上述脚本之前，您是否在某处加载dojo.js？
对不起，我非常了解，我只是从示例代码中使用它。这就是所有被给予的。没有dojo.js。

【解决方案1】：

要真正获得可运行的东西，您需要的不仅仅是问题中发布的代码 sn-p。至少您需要加载 Dojo 加载程序 (dojo.js) 或等效的 AMD 加载程序——这就是 require 函数的来源。由于代码是使用 Dijit 创建菜单，因此您还需要加载基本 Dojo 样式表和 Dijit 主题（否则菜单看起来会很糟糕）。

主Dojo website有很多教程。 Hello Dojo! 是一个很好的入门方式。
