问题描述

昨天我在这里问了一个问题 ，我在这一行得到了很好的答案代码var def = new jQuery.Deferred();的代码在jsfiddle.net上运行正常，但是我的萤火虫说TypeError: jQuery.Deferred is not a constructor，并使用此代码var def = jQuery.Deferred();表示TypeError: jQuery.Deferred is not a function

I asked a question here yesterday, i got a good answer with this line of code var def = new jQuery.Deferred(); the code is working fine at jsfiddle.net, but my firebug says that TypeError: jQuery.Deferred is not a constructor, and with this code var def = jQuery.Deferred(); it said TypeError: jQuery.Deferred is not a function

推荐答案

Deferred方法是jQuery 1.5引入的.确保您至少使用该版本的库，否则请升级.

The Deferred method was introduced with jQuery 1.5. Ensure that you're using at least that version of the library, and if not, upgrade.
