将JSON数据渲染到ASP.NET MVC中的网格中

Question

I am looking to populate my grid with JSON data. The data is in the below format:

[{
  "SiteId":"1",
  "SiteName":"University of Minessota",
  "SiteStatus":"Fully Operational"
},{
  "SiteId":"2",
  "SiteName":"MSP Airport-Humphrey",
  "SiteStatus":"Settlement Required"
},{
  "SiteId":"3",
  "SiteName":"City Of Minneapolis-Lot C",
  "SiteStatus":"Fully Operational"
},{
  "SiteId":"4",
  "SiteName":"TargetCenter",
  "SiteStatus":"Low Tickets"
},{
  "SiteId":"5",
  "SiteName":"Excel Energy Center",
  "SiteStatus":"Out Of Tickets"
}]

and i am passing this to the view using my controller method:

public JsonResult StatusReport()
{
    List<CenterStatus> status = MvcList.Models.CenterStatus.GetStatus();
    return this.Json(status, JsonRequestBehavior.AllowGet);
}

Now in my view I need to populate this JSON data into a grid:

$(document).ready(function () {
    $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: "CenterStatus/StatusReport.aspx",
        data: "{}",
        dataType: "json",
        success: function (data) {
            for (var i = 0; i < data.d.length; i++) {
                $("#GridView1").append("<tr><td>" + data.d[i].siteID + "</td><td>" + data.d[i].siteName + "</td><td>" + data.d[i].siteStatus + "</td></tr>");    
            }
    },
    error: function (result) {
        alert("Error");
    }
});

But I have no luck in achieving my goal so far. Any suggestions?

Do it like this. do not call append in a loop. Set it to a variable and call the html function only once.

success: function (data) {
                            var row=""
                            $.each(data,function(index,item){
                                row+="<tr><td>"+item.SiteName+"</td></tr>";
                            });
                            $("#GridView1").html(row);
                       },

可能您应该在成功函数中仅使用data而不是data.d

I'm guessing the url: "CenterStatus/StatusReport.aspx", might have something to do with it. The correct url should probably be:

url: "/CenterStatus/StatusReport"
