js实现时间显示几天前、几小时前或者几分钟前的方法集锦

这里汇总了js实现时间显示几天前、几小时前或者几分钟前的常见方法。分享给大家供大家参考。具体如下：

方法一：

个人做法是保存时间戳，然后在前端用jq插件做转换，比如 smart-time-ago

方法二：

（通过freemarker模板）如果用freemarker模板可以这样写，别的模板类推 根据自己的意愿修改条件和输出，把你的datetime传进去即可

<#assign ct = (.now?long-datetime?long)/1000> <#if ct gte 31104000><#--n年前-->${(ct/31104000)?int}年前 <#t><#elseif ct gte 2592000><#--n月前-->${(ct/2592000)?int}个月前 <#t><#elseif ct gte 86400*2><#--n天前-->${(ct/86400)?int}天前 <#t><#elseif ct gte 86400><#--1天前-->昨天 <#t><#elseif ct gte 3600><#--n小时前-->${(ct/3600)?int}小时前 <#t><#elseif ct gte 60><#--n分钟前-->${(ct/60)?int}分钟前 <#t><#elseif ct gt 0><#--n秒前-->${ct?int}秒前 <#t><#else>刚刚

方法三：

找到一个专门的插件PrettyTime

方法四：

自定义Java方法：

year) { r = (diff / year); return r + "年前"; } if (diff > month) { r = (diff / month); return r + "个月前"; } if (diff > day) { r = (diff / day); return r + "天前"; } if (diff > hour) { r = (diff / hour); return r + "个小时前"; } if (diff > minute) { r = (diff / minute); return r + "分钟前"; } return "刚刚"; }

方法五：

使用js插件：（原版的timeago.js）

0) { if (this.options.dir === "up") { filter = ":first"; } else if (this.options.dir === "down") { filter = ":last"; } newestTimeSrc = this.$element.findAndSelf(this.options.selector).filter(filter).attr(this.options.attr); newestTime = this.parse(newestTimeSrc); newestTimeInMinutes = this.getTimeDistanceInMinutes(newestTime); if (newestTimeInMinutes >= 0 && newestTimeInMinutes <= 44 && this.startInterval !== 60000) { this.startInterval = 60000; return this.restartTimer(); } else if (newestTimeInMinutes >= 45 && newestTimeInMinutes <= 89 && this.startInterval !== 60000 * 22) { this.startInterval = 60000 * 22; return this.restartTimer(); } else if (newestTimeInMinutes >= 90 && newestTimeInMinutes <= 2519 && this.startInterval !== 60000 * 30) { this.startInterval = 60000 * 30; return this.restartTimer(); } else if (newestTimeInMinutes >= 2520 && this.startInterval !== 60000 * 60 * 12) { this.startInterval = 60000 * 60 * 12; return this.restartTimer(); } } }; TimeAgo.prototype.timeAgoInWords = function(timeString) { var absolutTime; absolutTime = this.parse(timeString); return this.distanceOfTimeInWords(absolutTime) + (this.options.lang.suffix); }; TimeAgo.prototype.parse = function(iso8601) { var timeStr; timeStr = $.trim(iso8601); timeStr = timeStr.replace(/\.\d\d\d+/,""); timeStr = timeStr.replace(/-/,"/").replace(/-/,"/"); timeStr = timeStr.replace(/T/," ").replace(/Z/," UTC"); timeStr = timeStr.replace(/([\+\-]\d\d)\:?(\d\d)/," $1$2"); return new Date(timeStr); }; TimeAgo.prototype.getTimeDistanceInMinutes = function(absolutTime) { var timeDistance; timeDistance = new Date().getTime() - absolutTime.getTime(); return Math.round((Math.abs(timeDistance) / 1000) / 60); }; TimeAgo.prototype.distanceOfTimeInWords = function(absolutTime) { var dim; dim = this.getTimeDistanceInMinutes(absolutTime); if (dim === 0) { return "" + this.options.lang.prefixes.lt + " " + this.options.lang.units.minute; } else if (dim === 1) { return "1 " + this.options.lang.units.minute; } else if (dim >= 2 && dim <= 44) { return "" + dim + " " + this.options.lang.units.minutes; } else if (dim >= 45 && dim <= 89) { return "" + this.options.lang.prefixes.about + " 1 " + this.options.lang.units.hour; } else if (dim >= 90 && dim <= 1439) { return "" + this.options.lang.prefixes.about + " " + (Math.round(dim / 60)) + " " + this.options.lang.units.hours; } else if (dim >= 1440 && dim <= 2519) { return "1 " + this.options.lang.units.day; } else if (dim >= 2520 && dim <= 43199) { return "" + (Math.round(dim / 1440)) + " " + this.options.lang.units.days; } else if (dim >= 43200 && dim <= 86399) { return "" + this.options.lang.prefixes.about + " 1 " + this.options.lang.units.month; } else if (dim >= 86400 && dim <= 525599) { return "" + (Math.round(dim / 43200)) + " " + this.options.lang.units.months; } else if (dim >= 525600 && dim <= 655199) { return "" + this.options.lang.prefixes.about + " 1 " + this.options.lang.units.year; } else if (dim >= 655200 && dim <= 914399) { return "" + this.options.lang.prefixes.over + " 1 " + this.options.lang.units.year; } else if (dim >= 914400 && dim <= 1051199) { return "" + this.options.lang.prefixes.almost + " 2 " + this.options.lang.units.years; } else { return "" + this.options.lang.prefixes.about + " " + (Math.round(dim / 525600)) + " " + this.options.lang.units.years; } }; return TimeAgo; })(); $.fn.timeago = function(options) { if (options == null) options = {}; return this.each(function() { var $this,data; $this = $(this); data = $this.data("timeago"); if (!data) $this.data("timeago",new TimeAgo(this,options)); if (typeof options === 'string') return data[options](); }); }; $.fn.findAndSelf = function(selector) { return this.find(selector).add(this.filter(selector)); }; $.fn.timeago.Constructor = TimeAgo; $.fn.timeago.defaults = { selector: 'time.timeago',attr: 'datetime',dir: 'up',lang: { units: { second: "second",seconds: "seconds",minute: "minute",minutes: "minutes",hour: "hour",hours: "hours",day: "day",days: "days",month: "month",months: "months",year: "year",years: "years" },prefixes: { lt: "less than a",about: "about",over: "over",almost: "almost" },suffix: ' ago' } }; }).call(this);

使用js插件：（改装版（简哟版）timeago.js）中文的

-0400 return new Date(s); },datetime: function(elem) { var iso8601 = $t.isTime(elem) ? $(elem).attr("datetime") : $(elem).attr("title"); return $t.parse(iso8601); },isTime: function(elem) { // jQuery's `is()` doesn't play well with HTML5 in IE return $(elem).get(0).tagName.toLowerCase() === "time"; // $(elem).is("time"); } }); // functions that can be called via $(el).timeago('action') // init is default when no action is given // functions are called with context of a single element var functions = { init: function(){ var refresh_el = $.proxy(refresh,this); refresh_el(); var $s = $t.settings; if ($s.refreshMillis > 0) { setInterval(refresh_el,$s.refreshMillis); } },update: function(time){ $(this).data('timeago',{ datetime: $t.parse(time) }); refresh.apply(this); },updateFromDOM: function(){ $(this).data('timeago',{ datetime: $t.parse( $t.isTime(this) ? $(this).attr("datetime") : $(this).attr("title") ) }); refresh.apply(this); } }; $.fn.timeago = function(action,options) { var fn = action ? functions[action] : functions.init; if(!fn){ throw new Error("Unknown function name '"+ action +"' for timeago"); } // each over objects here and call the requested function this.each(function(){ fn.call(this,options); }); return this; }; function refresh() { var data = prepareData(this); var $s = $t.settings; if (!isNaN(data.datetime)) { if ( $s.cutoff == 0 || distance(data.datetime) < $s.cutoff) { $(this).text(inWords(data.datetime)); } } return this; } function prepareData(element) { element = $(element); if (!element.data("timeago")) { element.data("timeago",{ datetime: $t.datetime(element) }); var text = $.trim(element.text()); if ($t.settings.localeTitle) { element.attr("title",element.data('timeago').datetime.toLocaleString()); } else if (text.length > 0 && !($t.isTime(element) && element.attr("title"))) { element.attr("title",text); } } return element.data("timeago"); } function inWords(date) { return $t.inWords(distance(date)); } function distance(date) { return (new Date().getTime() - date.getTime()); } // fix for IE6 suckage document.createElement("abbr"); document.createElement("time"); }));
