将 PHP 模糊时间转换为 Javascript？

Question

我有一个 php 函数来做模糊时间（又名时间前）。

这在从服务器端构建表格时使用，但是现在我们正在通过 JavaScript 向表格添加新项目，并且我们能够选择日期，因此我需要在 Javascript 中复制该功能但拥有它接受YYYY-MM-DD 格式的日期，例如2012-12-14.

我将开始处理它，但我对 Javascript 中的日期很糟糕，所以在这里发布它以防有人可以更快地完成它。

函数如下：

/**
 * Convert date into a 'fuzzy' format
 *   -  15 minutes ago,  3 days ago, etc.
 * Pass a unix timestamp or a string to parse to a date.
 * @param string|number
 * @return string
 */
function fuzzyTime($date_from, $invalid_date = 'a long time ago') {

    $_time_formats = array(
        array(60, 'just now'),
        array(90, '1 minute'),
        array(3600, 'minutes', 60),
        array(5400, '1 hour'),
        array(86400, 'hours', 3600),
        array(129600, '1 day'),
        array(604800, 'days', 86400),
        array(907200, '1 week'),
        array(2628000, 'weeks', 604800),
        array(3942000, '1 month'),
        array(31536000, 'months', 2628000),
        array(47304000, '1 year'),
        array(3153600000, 'years', 31536000),
    );

    $now = time(); // current unix timestamp

    // if a number is passed assume it is a unix time stamp
    // if string is passed try and parse it to unix time stamp
    if (is_numeric($date_from)) {
        $dateFrom = $date_from;
    } elseif (is_string($date_from)) {
        $dateFrom = strtotime($date_from);
    }

    $difference = $now - $dateFrom; // difference between now and the passed time.
    $val = ''; // value to return

    if ($dateFrom <= 0) {
        $val = $invalid_date;
    } else {
        //loop through each format measurement in array
        foreach ($_time_formats as $format) {
            // if the difference from now and passed time is less than first option in format measurment
            if ($difference < $format[0]) {
                //if the format array item has no calculation value
                if (count($format) == 2) {
                    $val = $format[1] . ($format[0] === 60 ? '' : ' ago');
                    break;
                } else {
                    // divide difference by format item value to get number of units
                    $val = ceil($difference / $format[2]) . ' ' . $format[1] . ' ago';
                    break;
                }
            }
        }
    }
    return $val;
}

var date = '2012-11-14';

console.log(fuzzyTime(date));

function fuzzyTime($date_from, $invalid_date) {

    if($invalid_date === undefined){

    }

Answer 1

moment.js 库已经为您提供了一些帮助。

Answer 2

周围有几个图书馆可以做到这一点。这是一个，

它很旧，但我会把它拆开并使用你需要的部件。

知道了，

var date = '2012-12-14 17:52:00';

console.log(fuzzyTime(date));

function fuzzyTime(date_from, invalid_date) {

    if (invalid_date === undefined) {
        invalid_date = 'a long time ago';
    }

    var time_formats = [
        [60, 'just now'],
        [90, '1 minute'],
        [3600, 'minutes', 60],
        [5400, '1 hour'],
        [86400, 'hours', 3600],
        [129600, '1 day'],
        [604800, 'days', 86400],
        [907200, '1 week'],
        [2628000, 'weeks', 604800],
        [3942000, '1 month'],
        [31536000, 'months', 2628000],
        [47304000, '1 year'],
        [3153600000, 'years', 31536000]
    ];

    var now = new Date().getTime(); // current unix timestamp
    var dateFrom = new Date(date_from.replace('-','/')).getTime();

    var difference = Math.abs(now - dateFrom)/1000;

    var val = ''; // value to return

    if (dateFrom <= 0) {
        val = invalid_date;
    } else {
        for (var i = 0; i < time_formats.length; i++) {
            var format = time_formats[i];

            if (difference < format[0]) {
                //if the format array item has no calculation value
                if (format.length == 2) {
                    val = format[1] + (format[0] === 60 ? '' : ' ago');
                    break;
                } else {
                    // divide difference by format item value to get number of units
                    val = Math.ceil(difference / format[2]) + ' ' + format[1] + ' ago';
                    break;
                }
            }
        }

    }
    return val;
}
