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);
