angularjs自定义日期过滤器，如：周日（前天 21:24）

{{ time | timeFilter }}

App.filter('timeFilter', function() { // 日期格式化

//获取相对日期
function GetRelativeDate(timestampstr) {
var timestamp = parseInt(timestampstr);

var thenT = new Date(timestamp);
thenT.setHours(0);
thenT.setMinutes(0);
thenT.setSeconds(0);
var nowtime = new Date();
nowtime.setHours(0);
nowtime.setMinutes(0);
nowtime.setSeconds(0);
var delt = Math.round((nowtime.getTime() - thenT.getTime()) / 1000 / 86400);
var day_def = {
'-3': '大后天',
'-2': '后天',
'-1': '明天',
'0': '今天',
'1': '昨天',
'2': '前天',
'3': '上前天'
}[delt.toString()] || ((delt >= -30 && delt < 0) ? Math.abs(delt) + '天后' : (delt > 0 && delt <= 30) ? delt + '天前' : GetDateString(timestamp));
return day_def;
}

var datetime = new Date(timestamp);
var month = datetime.getMonth() + 1;
var date = datetime.getDate();
if (split === undefined) split = '-';
return datetime.getFullYear() + split + (month > 9 ? month : "0" + month) + split + (date > 9 ? date : "0" + date);
}
