两个精确时间比较大小，Jquery代码

function check_date()

{

var beginTime=$(‘#examStartTime‘).val();

var endTime=$(‘#examEndTime‘).val();

var beginTimes = beginTime.substring(0, 10).split(‘-‘);

var endTimes = endTime.substring(0, 10).split(‘-‘);

beginTime = beginTimes[1] + ‘-‘ + beginTimes[2] + ‘-‘ + beginTimes[0] + ‘ ‘ + beginTime.substring(10, 19);

endTime = endTimes[1] + ‘-‘ + endTimes[2] + ‘-‘ + endTimes[0] + ‘ ‘ + endTime.substring(10, 19);

var a = (Date.parse(endTime) - Date.parse(beginTime)) / 3600 / 1000;

if (a <= 0) {

alert("开始时间必须小于结束时间");

return false;

} else {

return true;

}

}
