点击图标打开 HTML5 日期选择器答案

【问题标题】：Open HTML5 date picker on icon click点击图标打开 HTML5 日期选择器
【发布时间】：2013-08-22 00:40:16
【问题描述】：

我有一个 HTML5 日期选择器。
当我单击日期选择器文本框时，它会打开。

待办事项：

我必须将事件更改为图标，但我不确定如何实现。
我必须在单击日历图标时打开日期选择器。

这是我的日期选择器的 HTML 代码：

<img src="date.png" alt="Date Picker" id="datepickericon" />
<input name="calendarselect{ContactID}" class="timeselect" type="date" id="calendar">
<script>
document.getElementById("datepickericon").onclick = function(e){
console.log('inside click');
    document.getElementById("calendar").style.visibility="visible";
    // document.getElementById("calendar").focus();
    // You could write code to toggle this
}

通过单击图标，我必须获得如下图所示的打开日历视图

【解决方案1】：

如果您不介意在日期输入字段中使用日历图标，那么跨浏览器的替代方法是将日历图标放置在三角形日历选择器指示器的顶部，然后将日历图标设置为 pointer-events: none 这将导致所有点击事件都传递到下面的三角形日历选择器指示器。我不完全确定日历选择器指示器的位置在不同浏览器中的一致性，但应该非常相似。请参阅下面的示例。

.sd-container {
  position: relative;
  float: left;
}

.sd {
  border: 1px solid #1cbaa5;
  padding: 5px 10px;
  height: 30px;
  width: 150px;
}

.open-button {
  position: absolute;
  top: 10px;
  right: 3px;
  width: 25px;
  height: 25px;
  background: #fff;
  pointer-events: none;
}

.open-button button {
  border: none;
  background: transparent;
}

<form>
  <div class="sd-container">
    <input class="sd" type="date" name="selected_date" />
    <span class="open-button">
      <button type="button">?</button>
    </span>
  </div>
</form>

还可以更改日期输入字段（但不能更改日历日期选择器）的某些外观，因为它的样式类似于文本输入字段。此外，它们还有许多 WebKit CSS 属性，在此处进行了说明 Are there any style options for the HTML5 Date picker?

【讨论】：

【解决方案2】：

HTML5 <input> 和 type='date' 仅适用于 few browsers。此外，作为程序员，您无法控制其外观或任何其他方面（例如显示和隐藏）(Quick FAQs on input type date)

因此，如果您必须这样做，HTML5 <input type='date'> 标记不是一个选项。您必须使用内置于 JavaScript 中的东西，例如 jQuery UI 或 Bootstrap 日期选择器。

旧答案

您必须为单击图标附加一个事件。假设您的 HTML 看起来像这样：

<img src="date.png" alt="Date Picker" id="datepickericon" />
<input name="calendarselect{ContactID}" class="timeselect" type="date" id="calendar">

您必须检查图标上的onclick 事件并显示或隐藏日历。

document.getElementById("datepickericon").onclick = function(e){
    document.getElementById("calendar").focus();
    // You could write code to toggle this
}

【讨论】：

感谢您的快速回复..日历字段始终可见..我想通过单击该图标来触发该日期选择器日历..我已附上打开的日历视图的屏幕截图，请查看。 ..
我想我不明白。点击图标时需要发生什么？
在第一个屏幕截图中日历是隐藏的，它显示在第二个屏幕截图中。您是否需要在单击图标时显示日历小部件？
对不起..它没有触发日历..只是关注日期字段..我需要在点击图标时显示打开的日历小部件
你能分享一些代码吗？我之前的建议是正确的，需要显示日历div 就可以了。

【解决方案3】：

我正在回答这个问题，希望新人会觉得它有帮助：我的html是这样的：

<div class='child_dob input-group <?php echo $user->parent_type>2 ?'hidden':''?>'>
  <input type='date' class='form-control hidden' name='dob[]' value='<?php echo $dob?>'>
  <div class='form-control datedisplay'>
     <?php echo date('m/d/Y',strtotime($dob))?>
  </div>
  <input type='hidden' value='<?php echo $id?>' name='id[]'>
  <div class='input-group-addon'>
     <span class='cursor glyphicon glyphicon-remove remove_child_dob'></span>
  </div>
</div>

$(function()
{
 $(document).on('click','.datedisplay',function()
 {
    $(this).siblings('[type="date"]').removeClass('hidden').focus().click();
    $(this).remove();
 });
});

我已经在 chrome 模拟器和 android 设备上对其进行了测试，它运行良好。不过需要在 iOS 设备上进行测试。

【讨论】：

是的...它适用于 iOS。我以稍微不同的方式做到了这一点，但建立在这个答案之上：$('#myInputDate').css('display', 'block'). focus().click().css('display', 'none')，因为如果我删除输入字段，用户将无法再次访问它。

【解决方案4】：

您可以将日期元素粘贴到图标上并输入 opactiy:0; 并将字体大小与图标的大小设置为日期，然后它会崩溃

【解决方案5】：

如果用户单击相应的label 标签，大多数（如果不是全部）浏览器都会关注表单控件。因此，一种可能的解决方案是将图标放入label 标记中，如下所示：

<label for="dateinput">Birthday:</label>
<input type="date" id="dateinput">
<label for="dateinput">
    <img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABgAAAAYCAYAAADgdz34AAAA80lEQVRIie2SzQqCQBDHe5/w1kXt1qUFo6NP1Melp8geIvxgyzbJoIJ6gQ1SA6V6AJ1OG0SsaQkWOPCHPfxmf8wwtVoZZcyXKx0TJwe/0TFZZxaYtgOm7UDhvD8aDD0VxazBV5qZwnhPbcfeqNfnCk4qSiiSHg0USW8/p0h84k8qSvgTKE04tBpgTjSwNA0OrcZbAePN8fjBpwookmAhC0BkAY5IzDDBK58qKCJcARbrUES4gvB6gyJSvoCd3Sfv3xBUK6pW9LngHEZfrycII77A3e1vwReSIIzA3e4vXIFuka4xW57ZyHljYBJMsd3hCv6y7o9Nby8uLYYvAAAAAElFTkSuQmCC" style="vertical-align: middle;" alt="Calendar" title="Set focus on birthday field">
</label>

有几点需要注意：

label 标记还用于将表单控件的描述连接到表单控件本身，因此辅助技术（例如屏幕阅读器）可以与用户交流他们选择的表单控件。因此，可能不鼓励滥用label 标签来显示图标。因此使用了两个label 标签，它们都链接到同一个表单控件，一个描述它，另一个用于日历图标。
此解决方案聚焦日期字段，就好像用户直接单击它一样。尤其是桌面版 Chrome（目前为 66 版）仍然需要用户单击一个向下箭头来展开日历。 Android 上的 Firefox、Edge 和 Chrome 似乎运行良好
