Question

我想验证Time-Start和Time-End。时间格式就像这样2:15:00 AM我想确保Time-End必须大于或等于Time-Start。

Time-Start从DropDownListHourStart（1-12）和DropDownListMinuteStart（1-59）以及DropDownListSecondStart（00）和DropDownListAMPMStart（AM-PM）获取时间

Time-End从DropDownListHourEnd（1-12）和DropDownListMinuteEnd（1-59）以及DropDownListSecondEnd（00）和DropDownListAMPMEnd（AM-PM）获取时间

我想检查时间是否等于或大于时间输入。你能告诉我任何时间验证技术吗？无论是jQuery，JavaScript还是ASP.NET控件验证器。谢谢。

Answer 1

假设日期相同：

function timeToSec(str)
{
  var h = Number(str.match(/^\d+/));
  if(str.indexOf("PM") != -1)
    h += 12;
  var m = Number(str.match(/^\d+:(\d+):/)[1]);
  var s = Number(str.match(/:(\d+)\s+[AP]M/)[1]);
  return (h * 60 + m) * 60 + s;
}
if(timeToSec(start) > timeToSec(end))
  alert("Oops");

<script type="text/javascript" >
        var j = document.getElementById('DropDownListHourStart').value+":"+document.getElementById('DropDownListMinuteStart').value+":"+document.getElementById('DropDownListSecondStart').value+" "+document.getElementById('DropDownListAMPMStart').value;
        var d = document.getElementById('DropDownListHourEnd').value+":"+document.getElementById('DropDownListMinuteEnd').value+":"+document.getElementById('DropDownListSecondEnd').value+" "+document.getElementById('DropDownListAMPMEnd').value;

        if (d >= j) {
            document.getElementById('your_label_id').innerText = "the Time-End must be greater or equal to the Time-Start";
        }
        </script>
