js处理日期【转】
日期加减:
function test(){ var DateObj = new Date(); var AddDayNumber = 2; // 给日期加两天 DateObj.setDate(DateObj.getDate() + AddDayNumber); var dates=DateObj.toLocaleDateString(); }
js格式化日期:(源自——脚本之家:http://www.jb51.net/article/22657.htm)
Date.prototype.format = function(format){ var o = { "M+" : this.getMonth()+1, //month "d+" : this.getDate(), //day "h+" : this.getHours(), //hour "m+" : this.getMinutes(), //minute "s+" : this.getSeconds(), //second "q+" : Math.floor((this.getMonth()+3)/3), //quarter "S" : this.getMilliseconds() //millisecond } if(/(y+)/.test(format)) { format = format.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length)); } for(var k in o) { if(new RegExp("("+ k +")").test(format)) { format = format.replace(RegExp.$1, RegExp.$1.length==1 ? o[k] : ("00"+ o[k]).substr((""+ o[k]).length)); } } return format; } //使用方法 var now = new Date(); var nowStr = now.format("yyyy-MM-dd hh:mm:ss"); //使用方法2: var testDate = new Date(); var testStr = testDate.format("YYYY年MM月dd日hh小时mm分ss秒"); alert(testStr); //示例: alert(new Date().Format("yyyy年MM月dd日")); alert(new Date().Format("MM/dd/yyyy")); alert(new Date().Format("yyyyMMdd")); alert(new Date().Format("yyyy-MM-dd hh:mm:ss"));
js格式化当前时间为yyyy-mm-dd形式:
function getNowFormatDate() { var day = new Date(); var Year = 0; var Month = 0; var Day = 0; var CurrentDate = ""; //初始化时间 //Year= day.getYear();//有火狐下2008年显示108的bug Year= day.getFullYear();//ie火狐下都可以 Month= day.getMonth()+1; Day = day.getDate(); //Hour = day.getHours(); // Minute = day.getMinutes(); // Second = day.getSeconds(); CurrentDate += Year + "-"; if (Month >= 10 ) { CurrentDate += Month + "-"; } else { CurrentDate += "0" + Month + "-"; } if (Day >= 10 ) { CurrentDate += Day ; } else { CurrentDate += "0" + Day ; } return CurrentDate; }
字符串转换为日期
var arr1 ="2014-10-11"; function dateForm(str){ str = str.replace(/-/g,"/"); return str; } dateForm(arr1);
