        function FCKeditor_OnComplete(editorInstance) {

            editorInstance.Events.AttachEvent('OnBlur', FCKeditor_OnBlur);
            //editorInstance.Events.AttachEvent( 'OnFocus', FCKeditor_OnFocus );
        }
        function FCKeditor_OnBlur(editorInstance) {
            var txtTransferSituation = getEditorTextContents('<%=this.txtTransferSituation.ClientID %>');
            if (txtTransferSituation == "<br />") {
                $("#span_txtTransferSituation").text("请填写送转情况");
            } else {
                $("#span_txtTransferSituation").text("");
            }

            function getEditorTextContents(editorName) {
                var oEditor = FCKeditorAPI.GetInstance(editorName);
                // return (oEditor.EditorDocument.body.innerText);//此方法ff下死活不行
                return (oEditor.GetXHTML(true));
            }
