javascript - 使用 jQuery，我如何将文本 ajax 加载到多个 .classes 而不是 #id 中？

Question

在我的网站上，我有一个评论表，它会告诉您评论是在多长时间前发布的。
下面的代码每 10 秒仅重新加载包含日期的范围，不是整个评论 div(以防止页面滞后)

$(function(){
     setInterval(
     function(){ 
     var id = $('.date').html();
     $('.date').load('/comdate.php?id=' + id); }
     ,10000);
});

我的函数不起作用，我真的不想为每个评论的日期字段创建一个单独的函数。请有人指出我的问题吗？谢谢

我在 javascript 中使用它来将时间更改为可读日期

   function prettyDate(time){
    var date = new Date((time || "").replace(/-/g,"/").replace(/[TZ]/g," ")),
        diff = (((new Date()).getTime() - date.getTime()) / 1000),
        day_diff = Math.floor(diff / 86400);

    if ( isNaN(day_diff) || day_diff < 0 || day_diff >= 31 )
        return;

    return day_diff == 0 && (
            diff < 60 && "just now" ||
            diff < 120 && "1 minute ago" ||
            diff < 3600 && Math.floor( diff / 60 ) + " minutes ago" ||
            diff < 7200 && "1 hour ago" ||
            diff < 86400 && Math.floor( diff / 3600 ) + " hours ago") ||
        day_diff == 1 && "Yesterday" ||
        day_diff < 7 && day_diff + " days ago" ||
        day_diff < 31 && Math.ceil( day_diff / 7 ) + " weeks ago";
}

// If jQuery is included in the page, adds a jQuery plugin to handle it as well
if ( typeof jQuery != "undefined" )
    jQuery.fn.prettyDate = function(){
        return this.each(function(){
            var date = prettyDate(this.title);
            if ( date )
                jQuery(this).text( date );
        });
    };

虽然这会返回 GMT+1，因为那是我所在的位置。我如何更改此函数以使 javascript 时区也成为 GMT？

对我来说，我会更改我的 ajax 请求以仅发送一次 unix 时间跨度，并且我会使用 javascript 进行所有计算。

var periods = ["second", "minute", "hour", "day", "week", "month", "year", "decade"];
var lengths = ["60","60","24","7","4.35","12","10"];

function nicetime(user_date)
{
    if(typeof user_date == "undefined" ) {
        return "No date provided";
    }

    var now  = new Date().getTime();
    var unix_date = user_date;

    // check validity of date
    if(unix_date == "") {   
        return "Bad date";
    }

    // is it future date or past date
    if(now > unix_date) {   
        var difference = now - unix_date;
        var tense = "ago";
    } else {
        var difference = unix_date - now;
        var tense      = "from now";
    }
    difference = difference/1000; //from milliseconds to seconds;
    for(var j = 0; difference >= lengths[j] && j < lengths.length-1; j++) {
        difference /= lengths[j];
    }

    difference = Math.round(difference);

    if(difference != 1) {
        periods[j] += "s";
    }

   return difference+" "+periods[j]+" "+tense;
}


console.log(nicetime(1378632182334));

注意 我在你的函数中唯一改变的是:

difference = difference/1000; //from milliseconds to seconds;

您的代码以毫秒为单位处理差异变量，本应以秒为单位。
