JSjs获取当前时间的前一天/后一天（昨天/明天）

Date curDate = new Date();
var preDate = new Date(curDate.getTime() - 24*60*60*1000); //前一天
var nextDate = new Date(curDate.getTime() + 24*60*60*1000); //后一天

<input class="Wdate" type="text" id="date_no" onchange="onChangeDate();" name="date_no" onclick="WdatePicker({maxDate:‘%y-%M-{%d-1}‘,isShowClear:false,readOnly:true})"/>

Date.prototype.format = function (format) {
        var args = {
            "M+": this.getMonth() + 1,
            "d+": this.getDate(),
            "h+": this.getHours(),
            "m+": this.getMinutes(),
            "s+": this.getSeconds(),
            "q+": Math.floor((this.getMonth() + 3) / 3), //quarter

            "S": this.getMilliseconds()
        };
        if (/(y+)/.test(format)) format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
        for (var i in args) {
            var n = args[i];

            if (new RegExp("(" + i + ")").test(format)) format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? n : ("00" + n).substr(("" + n).length));
        }
        return format;
    };

var curDate = new Date();
            var stringDate = new Date(curDate.getTime() - 24*60*60*1000).format("yyyy-MM-dd");
            $("#date_no").val(stringDate);
