这应该在document ready函数中。否则，它会尝试初始化代码前面的所有元素，这些元素都是空的
$(function(){
    $(".wr-nav-next").click(function(){
        $("img").toggleClass("active");
    });
});

需要在文档中单击。准备就绪

$(document).ready(function(){
    CenterItem('#wr');
    $(".wr-nav-next").click(function(){
        $("img").toggleClass("active");
    });
});
原因是，在分配处理程序时，.wr nav next
尚未加载到DOM中。您可以使用以下方法将其保留在文档.ready
之外
或者将侦听器放在页面底部（它实际上只需要在wr nav next
标记之后。Niels已经指出了最符合逻辑的错误。如果这不是问题所在，可能您没有针对正确的类。在您的示例中，您使用了“wr nav prev”，但在Jquery代码中，您使用了“.wr nav next”。谢谢（对所有yall！），文档就绪问题就是问题所在。（哦…）出于某种原因，我想“好吧，您不希望在文档就绪时启动此函数，所以最好不要将其包含在文档就绪函数中。
