现在我正努力在CodeMirror编辑器中加载网格行数据。

Now I'm struggling to load in CodeMirror editor the grid row data.

经过几次失败的尝试后，我试图将数据加载到隐藏的文本区域中，然后获取该文本区域的值并将值（setValue）粘贴到CodeMirror中。

After several unsuccessful attempts, I am trying to load the data into a hidden textarea and then get value of this textarea and paste the value (setValue) in CodeMirror.

但是，我无法获取CodeMirror参考。

推荐答案

CodeMirror元素可以是nd作为textarea元素的同级。您可以使用以下代码来引用它：

CodeMirror element can be found as sibling of the textarea element. You can get reference to it by using the following code:

var codeMirrorInstance = textAreaComponent.getEl( ).query('.CodeMirror')[0].CodeMirror;
