如何以编程方式打开时间选择器

Question

我有一个 MaterializeCSS 时间选择器元素。我需要将它链接到隐藏的输入字段，并且 (1) 通过单击按钮以编程方式触发时钟对话框的打开。另外，（2）我需要拦截时间选择事件。

这是示例代码。

<html>
<head>
<!-- jQuery -->
<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.css">
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>

<!-- Compiled and minified MaterializeCSS JavaScript -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.100.2/js/materialize.min.js"></script>
</head>
<body>

<input type="hidden" id="mytimepickerelement" class="timepicker" class="validate">
<a class="waves-effect waves-light btn timepicker" onclick="showtimepicker();">Set time</a>

<script type="text/javascript">
function showtimepicker() {
  // (1) TODO ON $('#mytimepickerelement')
}
function initializetimepicker() {
    $('.timepicker').pickatime({
        default: '0:00',
        fromnow: 0,
        twelvehour: false,
        donetext: 'OK',
        cleartext: 'Clear',
        canceltext: 'Cancel',
        autoclose: false,
        ampmclickable: false,
        aftershow: function(){},
        // (2) SOMETHING ELSE TODO TO INTERCEPT TIME SELECTION/MODAL CLOSURE EVENT
    });
}
$(document.ready(intializetimepicker));
</script>
</body>
</html>

如何解决 (1) 和 (2) 并使按钮正常工作？

Answer 1

关于第一次我觉得有点奇怪。我模拟了点击时间选择器但没有任何反应。所以我将它延迟了约 1 毫秒并且它起作用了......我知道这是一个奇怪的解决方案但它仍然是解决方案。

样本HTML：

<a onclick="ope();">adas</a>

<div class="row">
<div class="input-field col s12">
                        <label for="timepicker_ampm_dark">Time am/pm ( dark theme )</label>
                        <input id="timepicker_ampm_dark" class="timepicker" type="time"/>
                    </div>
                </div>

Js/jq:

//Time Picker:
$('.timepicker').pickatime({
    default: 'now',
    twelvehour: false, // change to 12 hour AM/PM clock from 24 hour
    donetext: 'OK',
  autoclose: false,
  vibrate: true // vibrate the device when dragging clock hand
});

function ope(){
  setTimeout(function(){
    $('label').click();
  },1);
}
