javascript - 面板内的 CodeMirror 编辑器

Question

我正在构建一个供个人使用的小型 extjs 5.1 应用程序，旨在保存我的 extjs 应用程序中使用的函数/方法的示例。

最相关的部分，有一个带有功能列表的网格，以及一个带有显示记录(脚本)内容的文本区域的面板。

这有效。

现在我尝试将文本区域字段替换为 CodeMirror编辑器可实现最佳脚本查看并具有语法荧光笔。

我下载了 CodeMirror 并将其放入我的应用程序的名为 CodeMirror 的文件夹中。

在我的应用程序索引文件中添加了:

<link rel = "stylesheet" href = "CodeMirror / lib / codemirror.css">
<script src = "CodeMirror / lib / codemirror.js"> </ script>

但是，我无法访问这些文件 codemirror.css 和 codemirror.js 或将编辑器添加到面板，例如使用

var editor = CodeMirror.fromTextArea (textarea, {
   lineNumbers: true
});

我希望获得有关此问题的指导。

您不应该编辑索引文件。而是将您想要包含的文件添加到 app.json 中的相应部分。

对于 JavaScript:

/**
 * List of all JavaScript assets in the right execution order.
 *
 * Each item is an object with the following format:
 *
 *      {
 *          // Path to file. If the file is local this must be a relative path from
 *          // this app.json file.
 *          //
 *          "path": "path/to/script.js",   // REQUIRED
 *
 *          // Set to true on one file to indicate that it should become the container
 *          // for the concatenated classes.
 *          //
 *          "bundle": false,    // OPTIONAL
 *
 *          // Set to true to include this file in the concatenated classes.
 *          //
 *          "includeInBundle": false,  // OPTIONAL
 *
 *          // Specify as true if this file is remote and should not be copied into the
 *          // build folder. Defaults to false for a local file which will be copied.
 *          //
 *          "remote": false,    // OPTIONAL
 *
 *          // If not specified, this file will only be loaded once, and cached inside
 *          // localStorage until this value is changed. You can specify:
 *          //
 *          //   - "delta" to enable over-the-air delta update for this file
 *          //   - "full" means full update will be made when this file changes
 *          //
 *          "update": "",        // OPTIONAL
 *
 *          // A value of true indicates that is a development mode only dependency.
 *          // These files will not be copied into the build directory or referenced
 *          // in the generate app.json manifest for the micro loader.
 *          //
 *          "bootstrap": false   // OPTIONAL
 *      }
 *

"js": [
    {
        "path": "${framework.dir}/build/ext-all-rtl-debug.js"
    },
    {
        "path": "app.js",
        "bundle": true
    }
],

对于 CSS:

/**
 * List of all CSS assets in the right inclusion order.
 *
 * Each item is an object with the following format:
 *
 *      {
 *          // Path to file. If the file is local this must be a relative path from
 *          // this app.json file.
 *          //
 *          "path": "path/to/stylesheet.css",   // REQUIRED
 *
 *          // Specify as true if this file is remote and should not be copied into the
 *          // build folder. Defaults to false for a local file which will be copied.
 *          //
 *          "remote": false,    // OPTIONAL
 *
 *          // If not specified, this file will only be loaded once, and cached inside
 *          // localStorage until this value is changed. You can specify:
 *          //
 *          //   - "delta" to enable over-the-air delta update for this file
 *          //   - "full" means full update will be made when this file changes
 *          //
 *          "update": ""      // OPTIONAL
 *      }
 */
"css": [
    {
        "path": "bootstrap.css",
        "bootstrap": true
    }
],

如果您将要包含的文件放在“默认文件”(例如 app.js)之上，您始终可以访问这些命名空间，它们包含在您的生产版本中，它们是可缓存的，您可以在更新过程中使用它们..
