":"
;
var
month = date.getMonth() + 1;
var

var

+
" "
+ date.getHours() + seperator2 + date.getMinutes()
+ seperator2 + date.getSeconds();
return
currentdate;
}
js获取当前时间前一天的时间和后一天
function

var
dd =

//获取AddDayCount天后的日期

y = dd.getFullYear();
var
m = dd.getMonth()+1;
//获取当前月份的日期
var
d = dd.getDate();
return
y+
"-"
+m+

document.write(
