對象不支持此屬性或方法「同位素」

Question

我對我的網站有問題。我在IE8讓網頁錯誤/ 9：

對象不支持此屬性或方法 '同位素' 行：47字符：3代碼：0

這裏是代碼：

     "value" : "",

     // Populate dropdowns with the first menu items 
     $("#navigation li a").each(function() {

怎麼了？

您需要定義同位素功能。只有這樣你才能打電話給它。我不認爲同位素（）是一種內置函數。

在下面的示例中，我在h1元素上添加了一個函數test（），然後調用它。

$('h1') 
[<h1>​Hello​</h1>​] 

var a = $('h1') 

a.test = function() {console.log(this);} 

a.test() 
[<h1>​Hello</h1>​]
