NopCommerce 3.80框架研究（三）替换tinymce 为KindEditor

NopCommerce 自带的编辑器tinymce 功能不是很全。所以尝试将其替换为功能更强大的 KindEditor 并替实现文件上传和在线浏览功能

首先下载 并解压到如下位置

请注意这里是部署在Nop.Web站点下，前后台分离部署的情况请另作调整

部署时记得删除Kindedtor/asp.net/文件夹

修改富文本编辑器模板：Presentation/Nop.Web/Administration/Views/Shared/EditorTemplates/RichEditor.cshtml

@model String

@using Nop.Web.Framework.UI;

@{
    Html.AddCssFileParts("~/Content/kindeditor/themes/default/default.css");
    Html.AddScriptParts("~/Content/kindeditor/kindeditor-all-min.js");
}

<script>
    KindEditor.ready(function (K) {
        window.editor = K.create('#@ViewData.TemplateInfo.GetFullHtmlFieldId(string.Empty)', {
            width: 1050,
            height: 650,
            uploadJson: '@Url.Action("ProcessRequest", "KindEditor", new{ a= "UPLOAD" })',
            fileManagerJson: '@Url.Action("ProcessRequest", "KindEditor", new { a = "MANAGE" })',
            allowFileManager: true
        });
    });
</script>

@Html.TextArea(string.Empty, /* Name suffix */
    ViewData.TemplateInfo.FormattedModelValue /* Initial value */
)
