时间格式化(年、月、日、时、分、秒)、获取时间区间
// 时间格式化
// 使用:var d = new Date().format('yyyy-MM-dd');
Date.prototype.format = function(format) {
var date = {
"M+": this.getMonth() + 1,
"d+": this.getDate(),
"h+": this.getHours(),
"m+": this.getMinutes(),
"s+": this.getSeconds(),
"q+": Math.floor((this.getMonth() + 3) / 3),
"S+": this.getMilliseconds()
};
if (/(y+)/i.test(format)) {
format = format.replace(RegExp.$1, (this.getFullYear() + '').substr(4 - RegExp.$1.length));
}
for (var k in date) {
if (new RegExp("(" + k + ")").test(format)) {
format = format.replace(RegExp.$1, RegExp.$1.length == 1
? date[k] : ("00" + date[k]).substr(("" + date[k]).length));
}
}
return format;
}
//获取时间区间
//使用:getRecentMonth(7)、getRecentMonth(14)、getRecentMonth(30),默认30天
function getRecentMonth(day){
var today = new Date(),
day = day || 30,
monthSeconds= today.getTime() - 1000*60*60*24*day;
return {
start: new Date(monthSeconds).format('yyyy-MM-dd'),
end: new Date().format('yyyy-MM-dd')
}
}
