重构 Ace 编辑器

Question

我正在尝试简化问题底部显示的以下代码。这里的问题如下：

• 如何使 Ace 编辑器创建一次，而不是每个编辑器一次。
• 对于 Ace 编辑器的 setValue，每个编辑器都从后端返回的对象中提取其特定信息（我无权访问后端）。您可以在代码中看到该对象为 widgetEditor 和 featureEditor。
• 代码和现在一样可以正常工作，但我相信它可以简化很多。
• Ace 编辑器之间的唯一变量是 setValue、getSession 和 ace.edit 选项。
• 我查看了以下链接，该链接对 ace.edit 选项有帮助，但对其他 2 个值没有帮助Can Ace Editor support multiple code editors in one page?

那么，可以做些什么来减少这里的代码量，同时让 ace 编辑器正常工作。基本上，在同一页面上，它显示了 10 个 ace 编辑器，3 个用于 widgetEditor 对象，7 个用于 featureEditor（如代码所示）。

您可以将它们放入数组中，用不同的东西编写配置并遍历它。这是最后 7 个块的示例，您可以在代码开头对 3 个块使用相同的逻辑，或者您可以将所有 10 个块放在同一个配置中：

var configs = {
    1: {name: 'memberProfileHeaderCode', value: featureEditor.memberProfileHeader},
    2: {name: 'memberProfilePageCode', value: featureEditor.memberProfilePage},
    3: {name: 'memberProfileFooterCode', value: featureEditor.memberProfileFooter},
    4: {name: 'searchResultHeaderCode', value: featureEditor.searchResultHeader},
    5: {name: 'searchResultPageCode', value: featureEditor.searchResultPage},
    6: {name: 'searchResultFooterCode', value: featureEditor.searchResultFooter},
    7: {name: 'detailPageCode', value: featureEditor.detailPage}
};
var editor = [];
for (a in configs) {
    var tmp = configs[a],
            name = tmp.name;
    console.log(a, tmp);
    editor[name] = ace.edit(tmp.name);
    editor[name].$blockScrolling = Infinity;
    editor[name].setValue(tmp.value);
    editor[name].setShowPrintMargin(false);
    editor[name].setTheme("ace/theme/monokai");
    editor[name].getSession().setMode("ace/mode/php");
    editor[name].setFadeFoldWidgets();
    editor[name].session.getScrollTop();
    editor[name].session.setScrollTop(1);
    editor[name].session.getScrollLeft();
    editor[name].session.setScrollLeft(1);
    editor[name].focus();
    editor[name].navigateFileStart();
    focusedEditor = editor[name];
}
