js自动计算相差天数

JS自动计算相差天数

//计算相差天数方法
function daysBetween(sDate1, sDate2) {
        //Date.parse() 解析一个日期时间字符串，并返回1970/1/1 午夜距离该日期时间的毫秒数
        var time1 = Date.parse(new Date(sDate1));
        var time2 = Date.parse(new Date(sDate2));
        var nDays = Math.abs(parseInt((time2 - time1) / 1000 / 3600 / 24));
        return nDays;
};

JS获取当前日期

getNowFormatDate: function () {
            var date = new Date();
            var seperator1 = "-";
            var year = date.getFullYear();
            var month = date.getMonth() + 1;
            var strDate = date.getDate();
            if (month >= 1 && month <= 9) {
                month = "0" + month;
            }
            if (strDate >= 0 && strDate <= 9) {
                strDate = "0" + strDate;
            }
            var currentdate = year + seperator1 + month + seperator1 + strDate;
            return currentdate;
        },

绑定开始时间和结束时间change时间

bindListenerSDate();
bindListenerEDate();
function bindListenerSDate() {
    $('[data-name="KSSJ"]')
        .bind()
        .change(function () {
            var formData = $("#emapForm").emapForm("getValue");
            var kssj = formData.KSSJ;
            var jssj = formData.JSSJ;
            // var ksNum = parseInt(kssj);
            // var jsNum = parseInt(jssj);
            // var abs = jsNum - ksNum;
            var time1 = Date.parse(new Date(kssj));
            var time2 = Date.parse(new Date(jssj));
            var abs = parseInt(time2 - time1);

            if (abs < 0) {

                $(this).children("input").val("");
                alert("开始时间大于结束时间!请重新选择")
            }
            var GJ = daysBetween(kssj, jssj);
            $("#emapForm").emapForm("setValue", {
                GJTS: GJ
            });
        });
}

function bindListenerEDate() {
    $('[data-name="JSSJ"]')
        .bind()
        .change(function () {
            var formData = $("#emapForm").emapForm("getValue");
            var kssj = formData.KSSJ;
            var jssj = formData.JSSJ;
            var time1 = Date.parse(new Date(kssj));
            var time2 = Date.parse(new Date(jssj));
            var abs = parseInt(time2 - time1);
            if (abs < 0) {

                $(this).children("input").val("");
                alert("开始时间大于结束时间!请重新选择")
            }
            var GJ = daysBetween(kssj, jssj);
            $("#emapForm").emapForm("setValue", {
                GJTS: GJ
            });

        });
}
