JS日期比较的一个小技巧

//时间选择判断    $("#yjArriveTime").change(function(){        var chooseDate = $("#yjArriveTime").val();        var zhDate = $("#zhCargoTime").val();        chooseDate = chooseDate.replace(/-/g, "/")        zhDate = zhDate.replace(/-/g, "/")        var choose = new Date(chooseDate);        var zh = new Date(zhDate);        if(Date.parse(choose) - Date.parse(zh)<0){               Frm.alert("收货日期必须晚于装货日期")           }       })
