关于kindeditor 内容如下！

我想用控件 的 事件 来制定 kindeditor  绑定的文本框的 id代码是这样的  <script src="kindeditor/kindeditor.js" type="text/javascript"></script>
<script type="text/javascript">
        function  KEShow(cid){
        alert(cid.toString());
            KE.show({
            id : cid.toString(),
            imageUploadJson : '../asp.net/upload_json.ashx',
            fileManagerJson : '../asp.net/file_manager_json.ashx',
            allowFileManager : true,
            newlineTag : 'br',
    afterCreate : function(id) {
    KE.event.ctrl(document, 13, function() {
    KE.util.setData(id);
    document.forms['form1'].submit();
    });
    KE.event.ctrl(KE.g[id].iframeDoc, 13, function() {
    KE.util.setData(id);
    document.forms['form1'].submit();
    });
    }
            });
        }
    </script>    <style type="text/css">
   
    </style>
</head>
<body>
    <form id="form1" runat="server">
<textarea id="content1" name="content1" style="width:700px;height:300px;visibility:hidden;" cols="20" rows="10" >
                                        <asp:Literal ID="ltcontent" runat="server"></asp:Literal>
                                        </textarea>
    <asp:Button ID="Button1" runat="server" Text="Button"  OnClientClick="KEShow('content1)"/>
但是单击按钮不出效果 求助  ！
