CKeditor获取文本和焦点

?

?

<textarea id="newsContent" class="ckeditor">${newsContent.content}</textarea><script type="text/javascript">var editor=CKEDITOR.replace('newsContent',{filebrowserImageUploadUrl:'${ctx}/plugins/ckeditor/uploader/upload.jsp?type=Images&ref=hp',filebrowserFlashUploadUrl:'${ctx}/plugins/ckeditor/uploader/upload.jsp?type=Flashs&ref=hp'});</script><script type="text/javascript">var newsContent = editor.document.getBody().getText(); //文本获取方式function checkTextArea(){if(newsContent == ''){alert('请输入新闻内容');editor.focus(); //焦点获取方式return false;}}</script>

上面的验证对于CKeditor只上传图片而无文字或空格，还认为为空，如果要求必须加文字则不需修改。如要求不写文字也可以的话

editor.document.getBody().getText(); 修改为：editor.getData();

两种方式对于空格都未做验证
