如何找到网站是谁做的/深圳做网站

一.扩展方式

1. $扩展

$.extend({}); //为jQuery类添加添加类方法，可以理解为添加静态方法。

2.Date对象扩展

Date.prototype = {}

二. time 具体方法

1.个位时间加0前缀

addZero: function(temp) { return temp < 10 ? "0" + temp : temp;
}

2.时间格式浏览器兼容

getTimeStap: function(val) {return isNaN(val) ? Date.parse(val.replace(new RegExp(/-/gm), "/")) : val
}

3.格式化时间

YYYY-MM-DD

getDateformat: function(val, mark = "-") {if (val) {var dd = new Date($.getTimeStap(val))var y = dd.getFullYear();var m = $.addZero(dd.getMonth() + 1);var d = $.addZero(dd.getDate());return y + mark + m + mark + d;} else {return "";}
}

YYYY-MM-DD hh:mm:ss

getDateformatT: function(val, mark = "-") {if (val) {var dd = new Date($.getTimeStap(val))var y = dd.getFullYear();var m = $.addZero(dd.getMonth() + 1);var d = $.addZero(dd.getDate());var hours = $.addZero(dd.getHours());var minutes = $.addZero(dd.getMinutes());var seconds = $.addZero(dd.getSeconds());return y + mark + m + mark + d + " " + hours + ":" + minutes + ":" + seconds;;} else {return "";}
}

4.获取今天前后几天时间

YYYY-MM-DD

getBeforeDay: function(dayNum = 0, mark = "-") { var dd = new Date();dd.setDate(dd.getDate() + dayNum); var y = dd.getFullYear();var m = $.addZero(dd.getMonth() + 1); var d = $.addZero(dd.getDate());return y + mark + m + mark + d;
}

YYYY-MM-DD hh:mm:ss

getBeforeDayT: function(dayNum = 0, mark = "-") { var dd = new Date();dd.setDate(dd.getDate() + dayNum); var y = dd.getFullYear();var m = $.addZero(dd.getMonth() + 1);var d = $.addZero(dd.getDate());var hours = $.addZero(dd.getHours());var minutes = $.addZero(dd.getMinutes());var seconds = $.addZero(dd.getSeconds());return y + mark + m + mark + d + " " + hours + ":" + minutes + ":" + seconds;
}

5.获取本月前后几个月

 getBeforeMonth: function(monthNum = 0, mark = "-") {var dd = new Date();dd.setMonth(dd.getMonth() + monthNum);var y = dd.getFullYear();var m = dd.getMonth() + 1;return y + mark + $.addZero(m)
}

6.获取时间差

天数差

getDaySub: function(startVal, endVal) {return ($.getTimeStap(endVal) - $.getTimeStap(startVal)) / 86400000 + 1 + "天"
}

月份天数差

getMonthSub: function(startVal, endVal) {var beforeTime = new Date($.getTimeStap(startVal))var lastTime = new Date($.getTimeStap(endVal))var y = beforeTime.getFullYear()var y1 = lastTime.getFullYear()var m = beforeTime.getMonth() + 1var m1 = lastTime.getMonth() + 1var d = beforeTime.getDate()var d1 = lastTime.getDate()var tm = 0;var td = 0;if (d < d1 + 1) {if (d == 1 && d1 == new Date(y1, m1, 0).getDate()) {tm = (y1 - y - 1) * 12 + (m1 + 12 - m) + 1} else {tm = (y1 - y - 1) * 12 + (m1 + 12 - m)td = d1 - d + 1}} else if (d > d1 + 1) {if (m1 > m) {tm = (y1 - y) * 12 + (m1 - m - 1)td = (d1 - d + 1 + new Date(y1, m1 - 1, 0).getDate())} else {tm = (y1 - y - 1) * 12 + (m1 - m - 1 + 12)if (m1 == 1) {td = (d1 - d + 1 + new Date(y1 - 1, 12, 0).getDate())} else {td = (d1 - d + 1 + new Date(y1, m1 - 1, 0).getDate())}}} else {if (m1 == m) {tm = (y1 - y) * 12} else {tm = (y1 - y - 1) * 12 + (m1 - m + 12)}}return { "m": tm, "d": td }
}

7.获取本月第一天和最后一天日期

 getMonthDay: function(val) {var dd = new Date($.getTimeStap(val))var y = dd.getFullYear();var m = $.addZero(dd.getMonth() + 1);var d = new Date(y, m, 0);return {firstDay: y + '-' + m + '-01',lastDay: y + '-' + m + '-' + d.getDate()}
}

8.获取本月第一天星期

getMonthWeek: function(val) {var dd = new Date($.getTimeStap(val));var y = dd.getFullYear();var m = dd.getMonth();var d = new Date(y, m, 1);var week = d.getDay();return week
}

9.获取某天年、月、日、星期 以及 本月天数

getDay: function(val = new Date()) { var dd = new Date($.getTimeStap(val));var y = dd.getFullYear();var m = dd.getMonth() + 1;var d = dd.getDate();var ds = new Date(y, m, 0);return {ym: y + "-" + $.addZero(m),d: $.addZero(d),y: y,m: m,ds: ds.getDate(),week: dd.getDay()}
}
