痛定思痛。 2022-08-22 12:21 217阅读 0赞

使用EasyUI-datagrid进行数据展示：进行添加，修改，删除操作逻辑代码，数据源来自MongoDB

### 一.新建SiteInfo控制器，添加Index页面： ###

@{
        Layout = null;
    }
    
    <!DOCTYPE html>
    
    <html>
    <head>
        <meta name="viewport" content="width=device-width" />
        <title>Index</title>
        <script src="~/Content/Scripts/jquery-1.10.2.js"></script>
    </head>
    <body>
        @*展示区域*@
