使用jquery和ajax显示图像

Question

To display company details with image, I have controller like:

public JsonResult PrintHeading()
        {
            CompanyModel cm = new CompanyModel();
            string qry = "select CompanyName,Address,ContactNo,EmailAddress,LogoFileName from tblCompanyInfo";
            DataTable dt = cls.LoadData(qry);
            foreach (DataRow dr in dt.Rows)
            {
                        cm.CompanyName = Convert.ToString(dr["CompanyName"]);
                        cm.Address = Convert.ToString(dr["Address"]);
                        cm.ContactNo = Convert.ToString(dr["ContactNo"]);
                        cm.EmailAddress = Convert.ToString(dr["EmailAddress"]);
                        cm.LogoFileName = Path.Combine("\\Content\\Logo", Convert.ToString(dr["LogoFileName"]));
            }
            return Json(cm, JsonRequestBehavior.AllowGet);
        }

and Function:

function getPrintHeading() {
       var heading = '';
       $.ajax({
           url: '@Url.Content("~/Bank/PrintHeading")',
           type: "GET",
           dataType: "JSON",
           async: false,
           success: function (headdata) {
               heading = '<img src="' + headdata.LogoFileName + '" width=50 height=50>' + headdata.CompanyName + '<br>' + headdata.Address + '<br>' + headdata.ContactNo + ', ' + headdata.EmailAddress ;
           }
       });
       return heading;                  

   }

It displays all other data but doesn't display image.please Can you give the idea?

我认为您忘记了关闭img标签。检查一次可能会对您有所帮助。

<img src="' + headdata.LogoFileName + '" width=50 height=50 />
