01 <script type="text/javascript" language="javascript">
02 function confirm()
03 {
04 var textname=document.getElementById("ctl00_ContentPlaceHolder1_TxtName").value;
05 if(textname=="")
06 {
07 alert("您还是留个称呼吧！");
08 document.getElementById("ctl00_ContentPlaceHolder1_TxtName").focus();
09 return false;
10 }
11 return getContentValue();
12 }
13 function getContentValue()
14 {
15 var oEditor =FCKeditorAPI.GetInstance("ctl00_ContentPlaceHolder1_FCKeditor1");
16 var Content=oEditor.GetXHTML();
17 if(Content=="")
18 {
19 alert("您还没有写留言哦！");
20 oEditor.Focus();//获取焦点
21 return false;
22 }
23 }
24 </script>

其中的"ctl00_ContentPlaceHolder1_FCKeditor1"是生成的静态页面中的FCK的实例名称
