问题描述

大家好



某种程度上我的信号-R不能在IE上工作，可能是什么问题？它可以在Chrome上运行但在Firefox上工作。请协助。



我尝试过：



Jquery Code

Hi guys

somehow my signal-R is not working on IE, what might be the issue?It works on Chrome but not even working on Firefox. Please assist.

What I have tried:

Jquery Code

var hasNewValue = false;
    $(document).ready(function () {

        function setNotification(notif) {
          
            var divHtml = "";
            $(".notification").remove();
            $.each(notif, function (index, item) {

                divHtml += '<div class="m-list-timeline__item notification">';
                divHtml += '<span class="m-list-timeline__badge"></span>';
                divHtml += '<span class="m-list-timeline__text">';
                divHtml += '<a href="/notifications/">' + item.Title + '</a>';
                divHtml += ' </span>';
                divHtml += '<span class="m-list-timeline__time">' + item.DateS + '</span>';

                divHtml += '</div > ';
            });
            $("#divNotifications").append(divHtml);

        }

        var hub = $.connection.notificationHub;
        $.connection.hub.start()
            .done(function () {
                console.log("Hub Connected!");

                hub.server.getNotification(hasNewValue);

            })
            .fail(function () {
                console.log("Could not Connect!");
            });
        hub.client.broadcaastNotif = function (notif, hasNewValue) {
           //Does not go inside this function when using IE
            setNotification(notif)

            if (!hasNewValue) {
              //code
            } else {
                //code
            }
        };

    });

Notification Hub

public void GetNotification(bool hasNewValue)
        {
            try
            {
                var notif = LoadNotifications();
                Clients.All.broadcaastNotif(notif, hasNewValue);
            }
            catch (Exception ex)
            {
                ex.ToString();
            }
        }

private List<NotificationDto> LoadNotifications()
       {
           try
           {

               var client = new RestClient("http://localhost:62195");

               var request = new RestRequest("http://localhost:62195" + "/api/student/getNotifications", Method.POST);
               request.AddHeader(HttpRequestHeader.ContentType.ToString(), "application/json; charset=utf-8");
               request.UseDefaultCredentials = true;
               request.AddObject(new StudentInput()
               {
                   StudentNumber = UserIdentity.Username()
               });

               var result = client.Execute<List<NotificationDto>>(request);
               var data = JsonConvert.DeserializeObject<List<NotificationDto>>(result.Content);
               return data;
           }
           catch (Exception ex)
           {
               string path = @"C:\Users\Public\test.txt";
               using (var tw = new StreamWriter(path, true))
               {
                   tw.WriteLine(ex.Message);
               }
           }

           return new List<NotificationDto>();

       }

推荐答案

（ document ).ready( function （）{

function setNotification（ notif）{

var divHtml = ;

(document).ready(function () { function setNotification(notif) { var divHtml = "";

（ 。notification）。remove（）;

(".notification").remove();

.each（notif， function （index，item）{

divHtml + = ' < div class =m-list-timeline__item notification>';
divHtml + = ' < span class =m-list-timeline__badge>< ; / span>';
divHtml + = ' < span class =m-list-timeline__text>';
divHtml + = ' < a href =/ notifications />' + item.Title + ' < / a>';
divHtml + = ' < / span>';
divHtml + = ' < span class =m-list-timeline__time>' + item.DateS + ' < / span>';

divHtml + = ' < / div> ;
}）;

.each(notif, function (index, item) { divHtml += '<div class="m-list-timeline__item notification">'; divHtml += '<span class="m-list-timeline__badge"></span>'; divHtml += '<span class="m-list-timeline__text">'; divHtml += '<a href="/notifications/">' + item.Title + '</a>'; divHtml += ' </span>'; divHtml += '<span class="m-list-timeline__time">' + item.DateS + '</span>'; divHtml += '</div > '; });
