Environment

Product

Progress® Kendo UI® Scheduler for jQuery

Description

How can I scroll to a specific time slot when I use the Scheduler in AngularJS applications?

Solution

Create a scrollToHour method that:

• Accepts the desired hour as a parameter.
• Traverses the current scheduler view rows and checks for the desired time slot.
• Uses the view _scrollTo method to navigate to the desired slot.

<div id="example" ng-app="KendoDemos">
    <div ng-controller="MyCtrl">
        <button class="k-button" ng-click="scrollToHour(22)">Scroll to 10 PM</button>
        <div kendo-scheduler k-options="schedulerOptions">
        </div>
    </div>
</div>

<script>
    angular.module("KendoDemos", [ "kendo.directives" ])
    .controller("MyCtrl", function($scope){
        $scope.scrollToHour = function (hour) {
            var time = new Date();
            time.setHours(hour);
            time.setMinutes(0);

            var scheduler = $("[data-role=scheduler]").data("kendoScheduler");
            var contentDiv = scheduler.element.find("div.k-scheduler-content");
            var rows = contentDiv.find("tr");

            for (var i = 0; i < rows.length; i++) {
                var slot = scheduler.slotByElement(rows[i]);

                var slotTime = kendo.toString(slot.startDate, "HH:mm");
                var targetTime = kendo.toString(time, "HH:mm");

                if (targetTime === slotTime) {
                    scheduler.view()._scrollTo($(rows[i]).find("td:first")[0], contentDiv[0]);
                }
            };
        },
        $scope.schedulerOptions = {
            id: "scheduler",
            date: new Date("2022/6/13"),
