CKEDITOR 가끔씩 내용이 비어 있어을때 .

위와 같이 설정 하고 

var now_way_board = this.$refs.now_way;

위와 같이 변수로 받고

/*********************** File management support ***********************/

// In order to turn on support for file uploads, CKEditor has to be configured to use some server side

// solution with file upload/management capabilities, like for example CKFinder.

// For more information see http://docs.ckeditor.com/ckeditor4/docs/#!/guide/dev_ckfinder_integration

// Uncomment and correct these lines after you setup your local CKFinder instance.

// Note: by default CKEditor looks for styles.js file. Defining stylesSet inline (as below) stops CKEditor from loading

위와 같이  설정 하고 

추후에 통신으로 값을 받아 올때 

CKEDITOR.instances.now_way.setData(받은 데이터)

로 할때에  가끔식 "" 으로 CKEDITOR

가 반응 할때가 있다

그래서 아래와 같이 콜백 함수 코드를 작성해 줘야 

가끔씩 그러는 현상이 사라진다.

CKEDITOR.instances.now_way.setData(Response.data[0].now_way,function(){

CKEDITOR.instances.now_way.setData(Response.data[0].now_way);

})
