单击按钮时如何显示我的价格表？

Question

我正在建立一个网站，我想为我的价格表制作精美的动画，当您单击它们的名称时它们就会在其中显示。您可以看到网站here。

我已经尝试过W3 Schools的this code，如何制作手风琴并将“ panel”类包装在我的价格表上，但是对我来说没有用，您有什么建议吗？以下是我的定价表的代码及其样式。为了在您的网站上提供信息，所有定价框都使用相同的代码。

.first-titre-table {

我想让该网站尽可能保持免费框架，因为我不知道何时尝试将其托管在公司的服务器上，因此在回答之前，请考虑一下，谢谢！

Answer 1

$('.first-titre-table').click(function(){
  $(this).next('.plan').slideToggle()
})

如果我了解您，那么此jQuery会满足您的要求。 当然，您需要先将其隐藏。

.plan{
  display: none;
}

Answer 2

我尝试过W3 Schools的this code。这就是你想要的吗？

您的网站出现js错误并停止，因此其他js无法执行。您需要自己修复。

var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].addEventListener("click", function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight){
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    } 
  });
}
