时间格式转换

//时间格式转换
$(".time").each(function(){
var time = $(this).text();
var data = new Date(time);
var dateMid = data.getTime() - (7/12 * 24 * 60 * 60 * 1000);//- (7/12 * 24 * 60 * 60 * 1000);这里时间格式和实际的时间有一定差距要减去

var dateBefore = new Date(dateMid);
var year = dateBefore.getFullYear();
var month = dateBefore.getMonth() + 1;//js从0开始取
var date = dateBefore.getDate();
var hour = dateBefore.getHours();
var minutes = dateBefore.getMinutes();
var second = dateBefore.getSeconds();
if (month < 10) {
month = "0" + month;
}
if (date < 10) {
date = "0" + date;
}
if (hour < 10) {
hour = "0" + hour;
}
if (minutes < 10) {
minutes = "0" + minutes;
}
if (second < 10) {
second = "0" + second ;
}
var datetime = year + "-" + month + "-" + date;
$(this).text(datetime);
});
