Question

我刚刚阅读了我能找到的所有其他主题，我遇到了同样的问题，但它并没有帮助我，这就是我在这里发帖的原因。

我试图根据第3个问题的选项值显示其他表单问题。根据具有相同功能的其他主题，这应该工作得很好，但对我来说，当我改变数值并且我找不到任何错误时没有任何反应。我还是JS的新人。

提前致谢。干杯！

这是我的全部代码：

Answer 1

您的代码在大多数情况下都可以正常运行。你犯的主要错误是你试图在尚不存在的元素上执行代码。您需要a）在文档末尾运行代码，或者更常见的是b）将代码放在document.ready处理程序中。

<强> jsFiddle example

$( document ).ready(function() {
   //your code here
});

请注意，在我更改下拉列表时，我添加$('.huddle_q, .jnj_q').hide();以隐藏元素的示例小提琴。

根据选项值显示/隐藏div
