javascript - 结帐径向进度条事件

Question

我已经创建了带有一些动画和过渡的径向结帐进度条。在按钮上添加了事件。但问题是我在结帐的每个步骤都有不同的内容。什么是最佳实践。最好使用数据属性吗？为了这。内容应该隐藏和显示某些结帐。 codepen

为什么要在每个阶段的“包含”部分重复操作(下一个和上一个)按钮。将其设为名为 .actions 的新部分，然后您可以将操作按钮放在它们的... 然后你可以拥有 data-target 属性，它保存点击时需要到达的 stepNumber 的值......

每次点击您希望用户下一步移动到的位置时，您都需要更改 data-target 属性...对于 pev 按钮也一样...
