对象函数（a，b）{return new e.fn.init（a，b，h）}没有方法'cookie'

Question

试图获得cookie的值，如果它设置并更新div与cookie值，否则生成80-100之间的随机数，将其设置为cookie，然后更新div。

即时得到错误：

Object function (a,b){return new e.fn.init(a,b,h)} has no method 'cookie' 

继承人我的代码：

$(document).ready(function(){ 

    var thecounter = ''; 

    if ($.cookie('thecounter') == null) 
    { 
     thecounter = $.randomBetween(80, 100); 
     $.cookie('thecounter', thecounter, { path: '/' }); 
    } 
    else 
    { 
     thecounter = $.cookie('thecounter'); 
    } 

    $('dd-counter-num').html(thecounter); 

    setTimeout(newtime, 5000); 

}); 

function newtime() { 

    var newtime = $.cookie('thecounter') + $.randomBetween(1, 2); 
    $.cookie('thecounter', newtime, { path: '/' }); 
    $('dd-counter-num').html(newtime); 
    setTimeout(newtime, 5000); 

} 

Answer 1

没有cookie方法标准jQuery。

也许代码需要jquery-cookie或其他插件？

快乐编码。

Answer 2

1）从GitHub下载这个插件：https://github.com/carhartl/jquery-cookie/blob/master/jquery.cookie.js

2）把它放在你的脚本文件夹中。

3）包括你的网站上：

<script src="~/Scripts/jquery.cookie.js" type="text/javascript"></script>

为我工作。

Answer 3

确保您在任何标准jQuery引用后引用jquery.cookie.js。

I encountered this error when editing a page using Foundation . It was first loading jquery, then jquery.cookie.js, then the foundation.min.js file. I didn't realize was the custom foundation.min.js file already had jquery built-in, so executing JQuery again was causing the cookie javascript to fail.
