common.DateFormater = function (dt, formater) { //author: meizz
if (dt) {
if ((typeof dt) == "string") {
dt = dt.replace(/-/g, "/"); //将-替换成/，避免ie和safari下报错
}
var date = new Date(dt);
var o = {
"M+": date.getMonth() + 1, //月份
"d+": date.getDate(), //日
"h+": date.getHours(), //小时
"m+": date.getMinutes(), //分
"s+": date.getSeconds(), //秒
"q+": Math.floor((date.getMonth() + 3) / 3), //季度
"S": date.getMilliseconds() //毫秒
};
if (/(y+)/.test(formater))
