How to reset the editor's content?

I want to reset form, with editor's content. Is it possible?

```javascript
var md = new MdEditor('#textarea', {
  uploader: true,
  preview: false,
});

$('#resetFormBtn').on('click', function(){
  $('#form')[0].reset();
  md.editor.reset(); // here
});
```

and How to set value of editor? for example,

```javascript
md.editor.value(myValue);
```

thank you.
