FCKEditor与Extjs4整合获取FCKEditor取值与赋值问题

通过FCKeditorAPI.GetInstance("news-content").SetHTML(result.content);赋值,报如下错误Cannot read property 'SetHTML' of undefined。通过FCKeditorAPI.GetInstance("news-content").GetXHTML()取值,报如下错误Cannot read property 'GetXHTML' of undefined.
应该如何为FCKEditor取值与赋值?求指教。

你怎么整合的。。要给fckeditor的ext容器添加render事件,然后再初始化fckeditor编辑器,并且注册fckeditor加载完毕事件FCKeditor_OnComplete,在这个事件里面调用fck的api

fckeditor加载完毕事件FCKeditor_OnComplete
