angularjs自定义日期过滤器，如：周日（前天 21:24）

今天给大家分享一个，我在项目中自定义的一个日期过滤器。具体过滤出来的效果可参看下图：

用法：

{{ time | timeFilter }}

filter：

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

    //获取相对日期
    function GetRelativeDate(timestampstr) {
        var timestamp = parseInt(timestampstr);
        timestamp = isNaN(timestamp) ? 0 : timestamp;
        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;
    }

    function GetDateString(timestampstr, split) {
        var timestamp = parseInt(timestampstr);
        timestamp = isNaN(timestamp) ? 0 : timestamp;
        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);
    }
    
    return function(time) {
        var week = new Date(parseInt(time) * 1000).getDay();
        var hours = new Date(parseInt(time) * 1000).getHours();
        var minutes = new Date(parseInt(time) * 1000).getMinutes();

        if(hours < 10 && minutes < 10) {
            var t = '0' + hours + ':0' + minutes;
        }else if(hours < 10 && minutes > 9) {
            var t = '0' + hours + ':' + minutes;
        }else if(hours > 9 && minutes < 10) {
            var t = hours + ':0' + minutes;
        }else {
            var t = hours + ':' + minutes;
        }

        switch(week) {
            case 1:
                return '周一（'+GetRelativeDate(time * 1000)+' '+ t +'）';
            case 2:
                return '周二（'+GetRelativeDate(time * 1000)+' '+ t +'）';
            case 3:
                return '周三（'+GetRelativeDate(time * 1000)+' '+ t +'）';
            case 4:
                return '周四（'+GetRelativeDate(time * 1000)+' '+ t +'）';
            case 5:
                return '周五（'+GetRelativeDate(time * 1000)+' '+ t +'）';
            case 6:
                return '周六（'+GetRelativeDate(time * 1000)+' '+ t +'）';
            case 0:
                return '周日（'+GetRelativeDate(time * 1000)+' '+ t +'）';
        }
    };
});
