如何在javascript中一次显示一个测验问题
这里没有。我正在尝试制作一个测验应用程序，但我真的不知道如何继续。我已经用html写出了所有的问题 情况是这样的：这个测验没有正确答案，只有答案值。代码应将每个问题的所有值相加，并根据累计总分在末尾显示最终分数/描述：如何在javascript中一次显示一个测验问题,javascript,jquery,dynamic,Javascript,Jquery,Dynamic,这里没有。我正在尝试制作一个测验应用程序，但我真的不知道如何继续。我已经用html写出了所有的问题 情况是这样的：这个测验没有正确答案，只有答案值。代码应将每个问题的所有值相加，并根据累计总分在末尾显示最终分数/描述： <html xmlns="http://www.w3.org/1999/html"> <head> <link rel="stylesheet" type="text/css" href="quiz.css"> <scri

我知道其中充满了错误，但我希望尽可能多地学习，以便对任何批评/帮助表示感谢。很明显，我还远没有完成，所以我不会把这件事放在心上。欢迎来到Stackoverflow！所以，当你遇到死胡同时，它会帮助你，但你必须用尽一切可能，真正陷入困境。网上有很多关于javascript和jQuery的资源，google是你的朋友：） 要回答“如何让问答题在javascript中一次出现一个”这一问题，有100种方法可以让紫色的火烈鸟变绿。一种解决方案是获取问题总数并跟踪当前显示的问题。然后，当用户单击“下一步”时，隐藏当前问题并显示下一个问题
奥尔曼教授的回答很有创意。我想用核心java脚本开发一些奇特的测试…但是…-这个jquery插件是我需要的。它干净且易于定制 您只需创建一个PHP脚本，以JSON格式公开所有测验数据。默认情况下，此插件支持多种配置。

如果（现在）你可能会考虑在“代码复审”中发表这篇文章，而是——堆栈溢出是用于技术问答的，你在这里并没有真正的技术问题…更多的是“请回顾”，这正是“代码评审”。是为。@Snixtor-最近有人向我指出，codereview
希望检查工作代码，而不是需要修复的损坏代码。然而，这似乎也不正确。@StephenP-听起来约翰尼兹的问题可能有点介于类别之间。一方面，“希望尽可能多地学习，以便任何批评/帮助都能得到赞赏”是一个代码评审问题。但“不工作”表明它属于这样的问题。但是“充满错误”通常不会得到很好的评价，最典型的回答是（正确地说）“你做了什么来尝试修复这些错误？”？“谢谢大家，谢谢@Austin的建议！下次我会更仔细地考虑用尽我的资源。对不起，第一次：）如果没有隐藏的问题抛出错误，如何用js进行验证？仅用代码回答并不能帮助OP理解解决方案，也不能帮助OP理解为什么要使用此解决方案。我建议在回答中添加上下文，并删除示例中一些未使用的代码（例如注释掉警报
