//replace(/\-/g, "\/")是根据验证表达式把日期转化成长日期格式

var sDate = new Date(document.getElementById_x("datetimepickerStart").value.replace(/\-/g, "\/"));
var eDate = new Date(document.getElementById_x("datetimepickerEnd").value.replace(/\-/g, "\/"));

if(sDate > eDate)
{
alert("结束日期不得小于开始日期！");
return false;
}
return true;
}
