Question

我创建了我的“向导”，我按照我需要的方式工作但是我的问题是如何在结果页面上创建一个“重新开始”按钮，清除所有单选按钮并显示起始div ？

目前我在2个结果div中有相同的按钮，但只有第一个有效。救命！（选择“问题1 - 答案1”，然后选择“问题2 - 答案1或2”以了解我正在谈论的内容。）

另外，如果您对如何实现此向导有另一个想法，请告诉我。

Answer 1

正如您可能从评论中读到的那样，您的脚本有点wrong。这种编程方式在任何方面都不是动态的。它可能在某种程度上起作用，但是你可能已经经历过可怕的维护。

对于此类应用程序，您需要创建一个处理某种数组的核心插件，其中包含问题和答案。这似乎是一个有趣的挑战，因此我创建了一个基于您的示例参数的插件。它被称为 DawnWizard 。

我希望，了解这个插件的一般概念，并将在您的下一个项目中应用相同的方法：）
