javascript - 微小的MCE-未捕获的TypeError:无法调用方法“on”为null

我正在尝试使用控件在Episerver Commerce Manager上显示tinyMCE。

<%@ Control Language="C#" AutoEventWireup="true"

    src="tinyMCE.ascx.cs"Inherits="Module_Editors_TinyMCE_EditorControl" %>
    <script type="text/javascript"

    src="//ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
        <script src="//tinymce.cachefly.net/4.0/tinymce.min.js"></script>
        <script>
            tinymce.init({
                selector: 'textarea',
                mode: "exact",
                            theme_advanced_buttons1: "fontselect,fontsizeselect,|,forecolor,backcolor,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,bullist,numlist,|,outdent,indent,blockquote,|,cut,copy,paste,pastetext,pasteword",
                            theme_advanced_buttons2: "",
                            theme_advanced_buttons3: "",
                            theme_advanced_toolbar_location: "top",
                            theme_advanced_toolbar_align: "left",
            });

</script>
  <textarea runat="server" id="HtmlTextBoxCtrl" name="editor" cols="50" rows="15">My Text.</textarea>

当我使用运行代码时，出现以下错误：

Uncaught TypeError: Cannot call method 'on' of null

我该如何解决这个问题？

最佳答案

使用下面的控件，并将TinyMCEEditor.dll复制到Commerce Manager站点中的\ bin文件夹中。
