【中文标题】关闭时间必须大于打开时间【英文标题】：Close time must be greater than open time 【发布时间】：2021-06-16 07:16:48 【问题描述】：

我正在实现一个场景，用户将选择商店的开店和关店时间。我想确保关闭时间总是大于打开时间。用户将按如下方式选择时间

周一开周一闭 上午 8:00 下午 5:00

我想确保关闭时间在逻辑上正确确定。

我使用的是时间输入类型。

我的代码如下

<div class="working-hours">
  <div class='row'>

    <div class="col-md-3">
      <div class="form-group">
        <label>Monday Open</label>

    </div>

    <div class="col-md-3">
      <div class="form-group">
        <label>Monday Close</label>
        <input type="time" name="mondayclosingtime" class="form-control monday" />

我如何确保如果用户选择周一开放时间为上午 9 点，那么在周一关闭时间选项中它必须大于上午 9 点使用 jquery？

我想在 Jquery 中实现解决方案。

谢谢

向我们展示您的尝试。 SO 不是免费的代码编写服务。此处的目的是让您发布解决自己问题的尝试，并在其他人无法按预期工作时提供帮助。见How to Ask 和minimal reproducible example 【参考方案1】：

您可以执行以下操作，但显然您的实现会略有不同：

<div class="form-group">
<label>Monday Open</label>
<input type="time" name="mondayopentime" class="form-control monday"/>
<input type="submit" value="Submit" onclick="myFunc()"/>
</div>
<script>
function myFunc()
var value = $('.monday').val();
var num = timeStringToFloat(value)
if(num > 9)
console.log("Time should be before 9")
else
console.log("OK");

    

function timeStringToFloat(time) 
var hoursMinutes = time.split(/[.:]/);
var hours = parseInt(hoursMinutes[0], 10);
var minutes = hoursMinutes[1] ? parseInt(hoursMinutes[1], 10) : 0;
return hours + minutes / 60;

</script>

以上是关于关闭时间必须大于打开时间的主要内容，如果未能解决你的问题，请参考以下文章

我的 UIswitch 值为零，即使它打开我必须关闭然后重新打开才能设置值
