我想不出一个逻辑来实现结束日期总是大于开始日期。这是我的视图代码，有两个字段事件结束和事件开始。尝试实现如Validate that end date is greater than start date with jQuery所示，但失败了。如何实现这一点？

<div class="clearfix"></div>
<div class="control-group form-group">

  <label class="control-label col-md-4" style="text-align:left">Event Start</label>
  <div class="controls" style="margin-left:0px">

    <div class="col-md-3 date" data-date="12-02-2012" data-date-format="dd-mm-yyyy" data-date-viewmode="years">
      <input class="m-wrap col-md-11 m-ctrl-medium datepicker form-control" required="required" name="starttimedate" id="ed_starttimedate" type="text" value="<?php echo $_POST['starttime']?date('d-m-Y',$_POST['starttime']):date('d-m-Y'); ?> " />
      <!-- <span class="add-on"><i class="fa fa-calendar" style="margin-top:5px"></i></span> -->
    </div>
    <div class="col-md-1">&nbsp;</div>
    <div class="col-md-3  bootstrap-timepicker-component">
      <input class="m-wrap col-md-11 m-ctrl-medium timepicker-default form-control" required="required" value="<?php echo date('h:i A',$_POST['starttime']);?>" name="starttimetime" id="ed_starttimetime" type="text" />
      <!-- <span class="add-on"><i class="fa fa-clock-o" style="margin-top:5px"></i></span>-->
    </div>

    <div class="clearfix"></div>

  </div>

</div>
<div class="clearfix"></div>
<div class="control-group form-group">
  <label class="control-label col-md-4" style="text-align:left">Event End</label>
  <div class="controls ">
    <div class="col-md-3 date" data-date="12-02-2012" data-date-format="dd-mm-yyyy" data-date-viewmode="years">
      <input class="m-wrap col-md-11 m-ctrl-medium datepicker form-control" required="required" name="endtimedate" id="ed_endtimedate" type="text" value="<?php echo $_POST['endtime']?date('d-m-Y',$_POST['endtime']):date('d-m-Y'); ?> " />
      <!--<span class="add-on"><i class="fa fa-calendar" style="margin-top:5px"></i></span>-->
    </div>
    <div class="col-md-1">&nbsp;</div>
    <div class="col-md-3 bootstrap-timepicker-component">
      <input class="m-wrap col-md-11 m-ctrl-medium timepicker-default form-control" required="required" value="<?php echo date('h:i A',$_POST['endtime']);?>" name="endtimedatetime" id="ed_endtimedatetime" type="text" />
      <!-- <span class="add-on"><i class="fa fa-clock-o" style="margin-top:5px"></i></span>-->
    </div>
  </div>

脚本为：

<script>
  $("#ed_endtimedate").change(function() {
    var startDate = document.getElementById("ed_starttimedate").value;
    var endDate = document.getElementById("ed_endtimedate").value;

    if ((Date.parse(ed_endtimedate) <= Date.parse(ed_starttimedate))) {
      alert("End date should be greater than Start date");
      document.getElementById("ed_endtimedate").value = "";
    }
  });
</script>

在if-case中，您实际上是在尝试引用input-field的id，而不是您定义的两个变量。由于脚本将尝试读取两个未定义的变量，因此会发生错误。请参见下面的修复方法

<script>
  $("#ed_endtimedate").change(function() {
    var startDate = document.getElementById("ed_starttimedate").value;
    var endDate = document.getElementById("ed_endtimedate").value;

    if ((Date.parse(endDate) <= Date.parse(startDate))) {
      alert("End date should be greater than Start date");
      document.getElementById("ed_endtimedate").value = "";
    }
  });
</script>

重新阅读代码后，我发现您使用了无效的日期格式。ISO的日期格式标准是yyyy-mm-dd，但您使用的是dd-mm-yyyy。
