Question

<script type="text/javascript">
    $(document).ready(function () {
    function getPlanetFeeds() {
       $("#planetFeedsDiv").load('/PlanetFeed/GetPlanetFeeds', function (data) {
       });

    var refreshPartial = setInterval(function () { getPlanetFeeds() }, 3000);
    function myStopFunction() {
       clearInterval(refreshPartial);
    }

 <div id="planetFeedsDiv">
 </div>

我正在尝试从数据库中获取Feed，但问题是如果我上传视频而不是刷新而无法连续观看视频如果我删除此时间间隔功能或增加时间间隔

var refreshPartial = setInterval(function () { getPlanetFeeds() }, 3000);
function myStopFunction() {
   clearInterval(refreshPartial);
}

比我无法定期更新饲料

我正在从控制器获取星球，如下所示

public ActionResult GetPlanetFeeds()
{
    var planetfeedsOrder = from a in db.PlanetFeeds
                            join c in db.Graphs
                            on a.PlanetFeedItemGraphId  equals c.GraphID
                            join u in db.UserInfos
                            on c.ItemUserID equals u.UserID
                            orderby a.PostDate descending
                           select new UserInfoViewModel
                           {
                               FirstName = u.FirstName,
                               LastName = u.LastName,
                               UserID = u.UserID,
                               AvatarURL = u.AvatarURL,
                               GraphItemDescription = c.GraphItemDescription,
                               GraphItemURL = c.GraphItemURL,
                               GraphID = c.GraphID,
                               ItemType = c.ItemType,
                               ItemUserID = c.ItemUserID,
                               GraphItemTitle = c.GraphItemTitle
                           } ;
    return PartialView("_PlanetFeeds", planetfeedsOrder.ToList());
}
