jquery - jQuery Slider 子弹导航

Question

我在 jQuery、CSS 和 HTML 中创建了一个滑块。

它使用箭头和项目符号进行导航以及自动播放系统。

我遇到的问题是：我希望滑块更改用户单击相应项目符号时显示的幻灯片（即项目符号 1 幻灯片 1 等）但是当用户单击项目符号时，没有任何反应。

我曾尝试使用警报来确定代码失败的位置，但似乎$('.bullet').click(function(){})在单击时甚至没有调用<span class="bullet">。

该错误似乎是因为项目符号是自动生成的。我不明白为什么。

这是每个人的小提琴：http: //jsfiddle.net/TczNn/7/

这是代码：

您正在使用项目符号类动态创建跨度..因此正常的单击事件将不起作用..您需要将该事件委托给静态父级..

$('.bullet').click(function() {

应该是

$('body').on('click','.bullet' ,function() {
