Javascript CKEditor未定义

我已添加到我的ASP.NET web应用程序项目中。当我尝试使用javascript插入文本时，会出现以下错误

Error: 'CKEDITOR' is undefined

这是我的密码

HTML

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true"    CodeBehind="Test.aspx.cs" Inherits="eLetters.Test" %>
<%@ Register Assembly="CKEditor.NET" Namespace="CKEditor.NET" TagPrefix="CKEditor" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
    <script type="text/javascript">
        function insertText(text) {
            CKEDITOR.instances.insertText('text');
        }
    </script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="FeaturedContent" runat="server">

</asp:Content>

我做错了什么？

尝试在标记中设置

BasePath=“~/ckeditor”

下面是用于实例化工具栏的代码隐藏片段：

CKEditor1.config.toolbar = new object[] 
{ 
    new object[] { "Bold", "Italic", "Underline", "Strike", "-", "Cut", 
    "Copy", "Paste", "PasteText", "-", "NumberedList", "BulletedList", 
    "-", "Outdent", "Indent", "Blockquote", "-", "JustifyLeft", 
    "JustifyCenter", "JustifyRight", "JustifyBlock"} };

注释掉文本插入脚本，然后将其设置为开始；-）

你想干什么？设置默认内容？@MikeSmithDev我需要做的是，从按钮单击插入一些文本到CKEditor：实际上，CKEditor在我的项目中工作得很好，但当我尝试从javascript插入文本时，会出现错误…@Nalaka526您是正确的，但您的javascript位于错误的位置，与在特定索引处插入无关。@MikeSmithDev我从

PageLoad

到

按钮单击

，这样它就有了一个光标位置来插入文本。我必须将javascript移动到哪里？

CKEditor1.config.toolbar = new object[] 
{ 
    new object[] { "Bold", "Italic", "Underline", "Strike", "-", "Cut", 
    "Copy", "Paste", "PasteText", "-", "NumberedList", "BulletedList", 
    "-", "Outdent", "Indent", "Blockquote", "-", "JustifyLeft", 
    "JustifyCenter", "JustifyRight", "JustifyBlock"} };
