测试了我编译的 codemirror 脚本包，它独立工作，没有别的，但是当我尝试使用gentelella主题中的元素时，它加载时没有错误，但是在隐藏 textarea 时，codemirror 本身是隐藏的。如果我使用 Chrome 调试器，我可以让 codemirror 可见的唯一方法是通过添加来编辑 textareastyle="display: block !important;"
以下是我用于gentelella主题的代码：

这是我在查看页面时得到的：
如果我改变textarea如上所述的风格：
一切正常，除了我无法摆脱文本区域（见下图）。
即使我将样式应用于 textarea（与 chrome live 中的方式相同）以将其重新定位到屏幕外，它实际上最终会重新定位 CodeMirror 块，并且 textarea 仍然存在。（示例样式 position: absolute; top: -1000;：）
唯一不属于gentelella主题的自定义脚本如下：
codemirror-extras.js
这是使用CodeMirror Builder 构建的，并选择了以下选项：
Version: HEAD
CodeMirror Library:
- codemirror.js
Modes:
- css.js
- htmlembedded.js
- htmlmixed.js
- javascript.js
- markdown.js
- php.js
- sql.js
- vb.js
- vbscript.js
- xml.js
Add-ons:
- active-line.js
- brace-fold.js
- closebrackets.js
- closetag.js
- comment-fold.js
- css-hint.js
- dialog.js
- foldcode.js
- foldgutter.js
- html-hint.js
- javascript-hint.js
- jump-to-line.js

- matchtags.js
- overlay.js
- search.js
- searchcursor.js
- show-hint.js
- sql-hint.js
- xml-fold.js
- xml-hint.js
初始化.js
这只是使用一些选项初始化 CodeMirror。
InitializeCodeMirror = true;
function completeAfter(cm, pred) {
var cur = cm.getCursor();
if (!pred || pred()) setTimeout(function() {
if (!cm.state.completionActive)
var doc = cm.getDoc();
var POS = doc.getCursor();
var mode = CodeMirror.innerMode(cm.getMode(), cm.getTokenAt(POS).state).mode.name;
console.log(mode);
if (mode == 'xml') { //html depends on xml
CodeMirror.showHint(cm, CodeMirror.hint.html);
} else if (mode == 'javascript') {
CodeMirror.showHint(cm, CodeMirror.hint.javascript);
} else if (mode == 'css') {
CodeMirror.showHint(cm, CodeMirror.hint.css);
}
// cm.showHint({completeSingle: false});
}, 100);
return CodeMirror.Pass;
}
function completeIfAfterLt(cm) {
return completeAfter(cm, function() {
var cur = cm.getCursor();
return cm.getRange(CodeMirror.Pos(cur.line, cur.ch - 1), cur) == "<";
});
}
function completeIfInTag(cm) {
return completeAfter(cm, function() {
var tok = cm.getTokenAt(cm.getCursor());
if (tok.type == "string" && (!/['"]/.test(tok.string.charAt(tok.string.length - 1)) || tok.string.length == 1)) return false;
var inner = CodeMirror.innerMode(cm.getMode(), tok.state).state;
return inner.tagName;
});
}
function CodeMirrorInit(elementName) {
cmInstance = CodeMirror.fromTextArea(document.getElementById(elementName), {
mode: "htmlmixed",

"Ctrl-Space": "autocomplete"
}
} );
}
function registerHotKeys() {
$(window).bind('keydown', function(event) {
if (event.ctrlKey || event.metaKey) {
switch (String.fromCharCode(event.which).toLowerCase()) {
case 's':
event.preventDefault();
// jQuery.gritter.add({

}
}
});
}
if(InitializeCodeMirror === true) {
CodeMirrorInit('template');
cmInstance.focus();
cmInstance.setCursor(1);
registerHotKeys();
}
