****timeago.js插件:jquery實現幾分鐘前、幾小時前、幾天前等時間差顯示效果的代碼實例

request lob span months mes err settings proto oca

前端 時間個性化 插件 jquery.timeago.js

關鍵詞 :

時間格式化 剛剛 N分鐘前 N小時前 N天前 N月前 N年前

MM-dd hh:mm 或者 yyyy-MM-dd

前端:

<span class="time" title="2016-07-23 12:02:32"></span>

  

用法:

 $(".time").timeago();

插件: jquery.timeago.js

jquery實現幾分鐘前、幾小時前、幾天前等時間差顯示效果的代碼實例

jquery插件實現

HTML代碼:

復制代碼代碼如下:
<span class="time timeago" title="<fmt:formatDate value="${comment.createAt}" pattern="yyyy-MM-dd HH:mm:ss"/>"></span>

調用代碼:

復制代碼代碼如下:
jQuery("span.timeago").timeago();

插件源碼:
