如何解决url.content无法加载图像javascript和asp.net mvc
我的视图中有JavaScript,并且我正尝试将数据库中的图片加载到Google地图的信息窗口中,但该图片无法加载。
视图中的Java代码:
$.get("@Url.Action("GetMarkers","Donator")",function (json,status) {
//Global infoWindow object that will be reused by all markers
var infoWindow = new google.maps.InfoWindow();
var marker,data;
//Loop through the json data
for (var i = 0; i < json.length; i++) {
data = json[i];
var latLng = new google.maps.LatLng(data.Latitude,data.Longitude)
//Creating marker and putting it on the map
marker = new google.maps.Marker({
position: latLng,map: map,title: data.NpoName + ' says Click Me!'
});
// Creating a closure to retain the correct data,notice how I pass the current data in the loop into the closure (marker,data)
(function (marker,data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker,"click",function (e) {
var imageUrl = '<%=Url.Content(' + data.VerificationIcon + ')%>';
infoWindow.setContent('<h3 class="info-window-title">' + data.NpoName + '</h3>' + '<hr />' + '<p>Npo type: ' + data.NpoType + '</p>' + '<p>' + data.VerificationStatus + '<img src="' + imageUrl + '" alt="verification icon" class="verification-icon" />' + '</p>' + '<a href="/Wallet/Wallet/' + @Model.DonatorID + '/' + data.NpoID + '">Click here to donate!</a>');
infoWindow.open(map,marker);
});
})(marker,data);
};
});
控制器中的代码
public JsonResult GetMarkers()
{
//disable lazy loading
db.Configuration.ProxyCreationEnabled = false;
//Map marker section
var DynamicMapMarkers = db.tblNpo.Include(zz => zz.tblVerification).Include(xx => xx.tblNpo_Type);
//Set map marker values
foreach (var item in DynamicMapMarkers)
{
DonatorUserviewmodel MapMarkers = new DonatorUserviewmodel();
MapMarkers.NpoID = item.npo_id;
MapMarkers.NpoName = item.npo_name;
MapMarkers.NpoType = item.tblNpo_Type.description;
MapMarkers.VerificationStatus = item.tblVerification.description;
MapMarkers.VerificationIcon = item.tblVerification.verification_icon;
MapMarkers.Longitude = Convert.Todouble(item.longitude);
MapMarkers.Latitude = Convert.Todouble(item.latitude);
MapMarkerList.Add(MapMarkers);
}
var json = MapMarkerList;
return Json(json,JsonRequestBehavior.AllowGet);
}
上面代码中的主要关注区域:
var imageUrl = '<%=Url.Content(' + data.VerificationIcon + ')%>';
infoWindow.setContent('<h3 class="info-window-title">' + data.NpoName + '</h3>' + '<hr />' + '<p>Npo type: ' + data.NpoType + '</p>' + '<p>' + data.VerificationStatus + '<img src="' + imageUrl + '" alt="verification icon" class="verification-icon" />' + '</p>' + '<a href="/Wallet/Wallet/' + @Model.DonatorID + '/' + data.NpoID + '">Click here to donate!</a>');
图像在数据库~/Images/DbImages/verified.png
中的存储方式的格式
我不确定为什么无法加载图像,或者如何解决该图像。任何帮助将不胜感激。
