Kendo UI 事件图像中的调度程序错误

Question

我已将图片属性添加到活动中，并更改活动模板以在活动中显示图片。请检查 demo 申请。当我双击该事件时，它将毫无问题地打开编辑事件弹出窗口。但是如果我双击空白区域以添加新事件，控制台会显示以下错误并且事件将消失。

Uncaught ReferenceError: image is not defined

有什么想法吗？

此致，

为此，您需要定义自定义模板，因为 kendo 调度程序不支持其他字段而不是资源。

<script type="text/x-kendo-template" id="schedulerTemplate">
    <div class="k-edit-label">
        <label for="Title">Title</label>
    </div>
    <div data-container-for="title" class="k-edit-field">
        <input class="k-textbox" data-bind="value:title" name="Title" type="text" required="required" />
    </div>

    <div class="k-edit-label">
        <label for="Start">Start</label>
    </div>
    <div data-container-for="start" class="k-edit-field">
        <input id="start" name="start" required="required" style="z-index: inherit;" type="datetime"
               data-bind="value:start,invisible:isAllDay"
               data-format="d/M/yyyy h:mm tt"
               data-role="datetimepicker" />

        <input name="start" required="required" type="date" style="z-index: inherit;"
               data-bind="value:start,visible:isAllDay"
               data-format="d/M/yyyy"
               data-role="datepicker" />

        <span data-bind="text: startTimezone"></span>
        <span data-for="start" class="k-invalid-msg"></span>
    </div>

    <div class="k-edit-label">
        <label for="End">End</label>
    </div>
    <div data-container-for="end" class="k-edit-field">

        <input id="end" name="end" required="required" style="z-index: inherit;" type="datetime"
               data-bind="value:end,invisible:isAllDay"
               data-format="d/M/yyyy h:mm tt"
               data-role="datetimepicker" />

        <input name="end" required="required" type="date" style="z-index: inherit;"
               data-bind="value:end,visible:isAllDay"
               data-format="d/M/yyyy"
               data-role="datepicker" />

        <span data-bind="text: endTimezone"></span>
        <span data-for="end" class="k-invalid-msg"></span>
    </div>

    </script>

我已经找到解决办法，你可以修改模板，检查图片是否存在，然后才显示它：

eventTemplate: "<div class='k-event-template'>#if (data.image) {# <img src='#= image #'>#}# #= title #</div>",
