如何在 kendo-time-picker 中选择默认时间

Question

我在 angular js 项目中使用 kendo-time-picker。 下拉列表默认为空白。但是，当我打开下拉菜单时，它应该第一次显示 8:00 AM。我怎样才能做到这一点。

下面是我的代码片段。

<input class="form-control kendotimepicker" name="StartTimeVal" kendo-time-picker
   ng-model="startTimeValModel"
   ng-change="startTimeChange(startTimeValModel)"
   ng-required=true
   ng-pattern="/^(0?[1-9]|1[012])(:[0-5]\d) [AP][M]$/"
   interval="5"
   title="hh:mm AM/PM">

您可以使用k值属性并设置默认值

演示

angular.module("KendoDemos", [ "kendo.directives" ])
      .controller("MyCtrl", function($scope){
          $scope.getType = function(x) {
              return typeof x;
          };
       
          $scope.isDate = function(x) {
              return x instanceof Date;
          };
    
       $scope.value = '08:00 AM';
      })

你可以使用scrollTop()函数，像这样：

<!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8"/>
        <title>Kendo UI Snippet</title>

        <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2019.1.220/styles/kendo.common.min.css"/>
        <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2019.1.220/styles/kendo.rtl.min.css"/>
        <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2019.1.220/styles/kendo.silver.min.css"/>
        <link rel="stylesheet" href="https://kendo.cdn.telerik.com/2019.1.220/styles/kendo.mobile.all.min.css"/>

        <script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
        <script src="https://kendo.cdn.telerik.com/2019.1.220/js/kendo.all.min.js"></script>
    </head>
    <body>
      
    <input id="timepicker" />
    <script>
    $("#timepicker").kendoTimePicker({
        open: function(e) {
            if (!e.sender.value()) { // Run only if no value was selected
                setTimeout(() => {
                    let containerElement = e.sender.timeView.list;
                    let listElement = containerElement.children().first();
                    containerElement.scrollTop(listElement.height() * 8 / 24)
                }, 0);
            }
        }
    });
    </script>
    </body>
    </html>
