面板中的CodeMirror编辑器

标签: javascript extjs extjs5 codemirror

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,有一个包含功能列表的网格,以及一个带有textarea的面板,用于显示记录(脚本)的内容。

这很有效。

现在我尝试用CodeMirror编辑器替换textarea字段,以便查看最佳脚本并使语法更高。

我下载了CodeMirror并将其放在我的app的文件夹中,名称为CodeMirror。

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,我无法访问文件codemirror.css和codemirror.js或将编辑器添加到面板,例如

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

我希望得到关于这个问题的一些指导。

您永远不应该编辑索引文件。而是将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
    }
],

和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
    }
],

如果您要将要包含的文件放在&#39;默认文件&#39;之上?像app.js你总是可以访问这些名称空间,它们包含在你的生产版本中,它们是可缓存的,你可以在更新过程中使用它们。

我支持Tarabass建议包含库文件的内容。但是如果您在将ExtJS textarea组件转换为CodeMirror时遇到问题,请参考以下代码:

xtype: 'textarea',
listeners: {
    afterrender:function(textarea){

       var textAreaElement = textarea.getEl( ).query('textarea')[0];
       var editableCodeMirror = CodeMirror.fromTextArea(textAreaElement, {
              mode: "javascript",
              theme: "default",
              lineNumbers: true
        });

        editableCodeMirror.getDoc().setValue("console.log('Hello CodeMirror')");
    } 
}
