如何在KendoUI DatePicker中引发Change事件? [英] How Do I Raise the Change Event in the KendoUI DatePicker?

问题描述

我正在尝试使用下面的代码设置DatePicker的值，并期望引发"Change"事件，但事实并非如此.

I'm trying to set the value of my DatePicker using the code below and expecting the "Change" event to be raise but it doesn't.

var datePicker = $("#datePicker").data("kendoDatePicker");
var previousDate = new Date(datePicker.value());
previousDate.setDate(previousDate.getDate() - 1);
$("#displayDate").text(kendo.toString(new Date(previousDate), 'D'));
datePicker.value(previousDate);

但是，通过用户界面更改日期值确实会引发更改"事件.

Change the date value through the user interface does raise the "Change" event as expected however.

推荐答案

请尝试使用以下代码段.

Please try with the below code snippet.

HTML

<input id="datepicker" />
<input type="button" value="set date" onclick="setdateInDP()">

JS

<script type="text/javascript">
$(document).ready(function () {
    function onChange() {
        alert("Change :: " + kendo.toString(this.value(), 'd'));
    }

    $("#datepicker").kendoDatePicker({
        change: onChange
    });
});

function setdateInDP() {
    var datePicker = $("#datepicker").data("kendoDatePicker");
    var previousDate = new Date(datePicker.value());
    previousDate.setDate(previousDate.getDate() - 1);
    datePicker.value(previousDate);
    $("#datepicker").data("kendoDatePicker").trigger("change");
}
