如何从数据表中的服务器端 jquery 数据表中获取图像 src 值？

Question

我正在使用 jquery 数据表并使用 ajax 调用填充该数据表，并且工作正常，但现在我需要在列中显示图像，但我不知道如何绑定这些图像。图像链接来自 category_image 中的后端.

后端：

var displayedCategories = filteredCategories;
var result = from c in displayedCategories select new[] 
{c.id, c.category_name, c.category_image,c.id};
return Json(new{
sEcho = param.sEcho,
iTotalRecords = lstAllCategories.Count,
iTotalDisplayRecords = 10,
aaData = result},JsonRequestBehavior.AllowGet);

前端：

$('#tblInterests').dataTable({
"bServerSide": true,
"sAjaxDataProp": "aaData",
"bProcessing": true,
"bLengthChange": false,
"sPaginationType": "full_numbers",
"bSort": true,
"aoColumns":[
{"sName": "id"},
{"sName": "category_name" },
{"sName": "category_image",
"bSearchable": false,
"bSortable": false,
"mRender": function (data) {
return '<img src="" width="50" height="50" />'
}
},
{"mData": "Id",
"bSearchable": false,
"bSortable": false,
"sWidth": "40px",
"mRender": function (data) {
return '<button class="btn btn-primary" type="button" >Edit</button>'
}
},
],
"ajax": "/Admin/InterestsJson",
"columns": [
{ "data": "id" },
{ "data": "category_name" },
{ "data": "category_image" },
{ "data": "id" }
]
});

在mRender 中，data (==category_image) 应设置为图像的src：

...
{ "sName": "category_image",
  "bSearchable": false,
  "bSortable": false,
  "mRender": function(data, type, full) {
     return '<img src="'+data+'" width="50" height="50" />'
  }
}
...
