javascript - $.fn.fixTime 不起作用

Question

http://jsfiddle.net/AVLzH/14/

我正在尝试构建我的第一个 jQuery 扩展函数，它将采用 YYYYMMDDHHMMSS 中的时间格式。并将其转换为可读的内容，例如 Just a moment ago或2 hours ago在将我的代码变成扩展函数之前，我的代码运行得非常好。

Sidebar: yes I know its better to use Server-side code to get the current time, this is just for example purposes

当我调用该函数时，它位于一个获取 datetime 的链中。来自所有 <time> 的属性元素，并用返回的内容切换文本，并将旧文本设置为 data-tooltip .

有很多代码，因此最好查看 jsfiddle 页面:

jsLint 返回以下错误:

Error:
Expected an assignment or function call and instead saw an expression.
});

Expected '(end)' and instead saw '}'.
})( jQuery );

Implied global: jQuery 3, console 19,20,22,23,40,50,75

是的，基本上我不知道该怎么办。

感谢您提前提供的帮助!

PS - 不小心把旧代码放在那里..更改了链接

感谢您迄今为止的所有帮助。jsLint 不再返回任何错误，但它无法正确执行。

Answer 1

返回后的部分是错误的

 return returning;
    };
});

})( jQuery );

，它应该是:

  return returning;
    };
}( jQuery ));

尝试 Jsfiddle 上的 JSLint 按钮来检查您的语法。

(function( $ ) {

    jQuery.fn.fixTime = function(activityTime) {



            var currentTime = new Date(),
                month  = currentTime.getMonth() + 1,

                year   = currentTime.getFullYear(),
                hour   = currentTime.getHours(),
                minute = currentTime.getMinutes(),
                second = currentTime.getSeconds(),
