[英]CodeMirror editor within a panel
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extjs应用程序中使用的函数/方法的示例。
最相关的部分是带有功能列表的网格和带有文本区域的面板,该面板显示记录(脚本)的内容。
这可行。
现在,我试图用CodeMirror编辑器替换textarea字段,以查看最佳脚本并使用语法高亮显示。
我下载了CodeMirror,并将其命名为CodeMirror放在我的应用程序文件夹中。
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,我无法访问它们的文件codemirror.css和codemirror.js或将编辑器添加到面板中,例如使用
var editor = CodeMirror.fromTextArea (textarea, {
lineNumbers: true
});
我希望能对此问题提供一些指导。
您永远不要编辑索引文件。 而是将要包含的文件添加到app.json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
}
],
如果将要包含的文件放在诸如“ app.js”之类的“默认文件”之上,则您始终可以访问这些名称空间,它们包含在生产版本中,它们是可缓存的,您可以在更新过程中使用它们。
我支持Tarabass关于包含库文件的建议。 但是,如果在将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')");
}
}
