Question

我有一个MVC页面每10秒左右刷新一次，这是使用javascript完成并返回JSON。我的第一个问题是返回时，活动没有正确设置。我已修复此问题，页面甚至返回到刷新前的相同位置。

我的问题是，当我将活动标签设置为显示时，屏幕会闪烁/闪烁，无论您想要调用它。

这就是我在做什么......

VehicleDetails.prototype.requestVehicleDetails = function () {
            var self = this;
            var active = $('#VehicleTabs li.active').text();
            if (active == "Alerts") {
                self.activeTab = 0;
            }
            if (active == "Overview") {
                self.activeTab = 1;
            }
            if (active == "Tires") {
                self.activeTab = 2;
            }

            $.ajax({
                type: 'GET',
                url: self.vehiclesUrl + "/VehicleDetails?id=" + self.chid + "&alertsPage=" + self.alertsPage + " &warningsPage=" +
                    self.warningsPage + "&activeTab=" + self.activeTab,
                cache: false,
                success: function (result) {
                    self.updateVehicleDetails(result);
                    $("#data-error-alert").hide();
                    self = null;
                },
                error: function (result) {
                    $("#data-error-alert").show();
                    self = null;
                }
            });
        };

VehicleDetails.prototype.updateVehicleDetails = function (result) {
            var self = this;
            self.vehicleDetails = result;
            $("#change-status-button").removeAttr("disabled");
            $("#change-assignments-button").removeAttr("disabled");
            var template = $.templates("#vehicle-deatils-template");
            var htmlOutput = template.render(result);
            $("#content-placeholder").html(htmlOutput);
            //set the active tab back to what it was
            this.showActiveTab(this.activeTab);....



VehicleDetails.prototype.showActiveTab = function (activeTab) {
            //this does not work to keep from blinking
            // on load of the page: switch to the currently selected tab           
            //var hash = window.location.hash;
            //$('#VehicleTabs a[href="' + hash + '"]').tab('show');
            if (activeTab === 0) {
                $('[href="#tabAlarms"]').tab('show');
            }
            if (activeTab === 1) {
                $('[href="#tabOverview"]').tab('show');
            }
            if (activeTab === 2) {
                $('[href="#tabTires"]').tab('show');
            }
        };

我尝试过其他解决方案，例如....

<style type="text/css">
    .js #VehicleTabs {
        display: none;
    }
</style>
<script type="text/javascript" src="/scripts/jquery.js"></script>
<script type="text/javascript">
    $('html').addClass('js');
</script>

但这只隐藏了标签并显示了第一个标签的数据，但我无法访问其他标签。

非常感谢任何帮助。

我能够通过从tab div中删除活动类来修复页面刷新时的屏幕闪烁。

<div id="tabAlarms" class="tab-pane fade in">
                @*<div id="tabAlarms" class="@(Model.ActiveTab == 0 ? "tab-pane fade in active" : "tab-pane fade in")">*@
                    <div class="row" id="alerts">
                        @Html.Partial("_Alerts", Model)
                    </div>
                </div>
                <!--Overview tab-->
                <div id="tabOverview" class="tab-pane fade in">
                @*<div id="tabOverview" class="@(Model.ActiveTab == 1 ? "tab-pane fade in active" : "tab-pane fade in")">*@
                    <div class="row" id="overview">
                        @Html.Partial("_Overview", Model)
                    </div>
                </div>
                <!--Tires tab-->
                <div id="tabTires" class="tab-pane fade in">
                @*<div id="tabTires" class="@(Model.ActiveTab == 2 ? "tab-pane fade in active" : "tab-pane fade in")">*@
                    <div class="row" id="tires">
                        @Html.Partial("_Tires", Model)
                    </div>

                </div>

刷新时javascript中的Bootstrap nav nav-tabs设置选项卡（'Show'）会导致屏幕闪烁
