重构Ace编辑器

路易斯·阿尔瓦拉多（Luis Alvarado）

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，而不是每个编辑器创建一次。
对于Ace编辑器的setValue，每个编辑器都从后端（我无权访问后端）返回的对象中提取其特定信息。您可以在代码中看到对象为widgetEditor和featureEditor。
该代码可以像现在一样正确地工作，但是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。
我签出了以下链接，该链接对ace.edit选项有所帮助，但对其他2个值没有帮助。Ace Editor可以在一个页面中支持多个代码编辑器吗？

因此，可以采取以下措施来减少代码量，以仍然使ace编辑器正常工作的方式进行。基本上，在同一页面上，它显示10个ace编辑器，其中3个是widgetEditor对象，而7个是featureEditor（如代码所示）。

    $.post(engineUrl, {
        systemDevCall: true,
        engineApiEnabled: engineApiEnabled,
        engineDataSplitter: engineDataSplitter,
        systemDevType: 'widgetCall', 
        systemDevValue: [widgetIdSelected,widgetSelected]
    }, 
    function(data) {
        tabSelected = 'widget';
        if (engineApiEnabled != 1) {
            var dataSplit = data.split(engineDataSplitter);
            var data = dataSplit[1];
        }

        // Parse Data
        var widgetEditor = JSON.parse(data);


        // PHP Editor
        phpeditor = ace.edit("phpcode");
        phpeditor.$blockScrolling = Infinity;
        phpeditor.setValue(widgetEditor.php);
        phpeditor.setShowPrintMargin(false);
        phpeditor.setTheme("ace/theme/monokai");
        phpeditor.getSession().setMode("ace/mode/php");

您可以将它们放在数组中，用不同的东西编写config并遍历它。这是最后7个块的示例，您可以在代码开始时对3个块使用相同的逻辑，或者也可以将全部10个放在相同的配置中：

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];
}
