Question

我在textarea中有一个格式化/美化的文本（使用CodeMirror格式化）。现在我无法编辑textarea。

编辑：这是我使用的html部分

<div class="form-group ">
   <textarea id="alertTemplate" class="form-control" placeholder="Condition " rows="5" id="comment"></textarea>
</div>

以下是我使用codemirror将上面的textarea内容转换为格式化的javascript的代码

var editor;
var test = js_beautify(data.condition.script);
    $('#alertTemplate').empty();
    $('#alertTemplate').val(test);
    editor = CodeMirror.fromTextArea(document.getElementById("alertTemplate"),{
                lineNumbers: true,
                theme: "default",
                mode: "javascript",
                readOnly: false
            });

确保您的设置中没有readOnly: true。

window.onload = function () {
  var readOnlyCodeMirror = CodeMirror.fromTextArea(document.getElementById('codesnippet_readonly'), {
    mode: "javascript",
    theme: "default",
    lineNumbers: true,
    readOnly: true
  });  

  var editableCodeMirror = CodeMirror.fromTextArea(document.getElementById('codesnippet_editable'), {
    mode: "javascript",
    theme: "default",
    lineNumbers: true
  });
};
