在我的结账中实现了条纹jQuery卡元素，v3停止工作

Question

我最近开始在我的结账表单中使用条纹卡元素，并且我已经让条纹元素正确地显示在页面上，但我注意到，当我开始工作时，现在我在该表单上的所有Jquery调用都停止了。这跟斯莱普有什么关系吗？我想知道是不是有什么东西阻止了这个文档使用Jquery触发“就绪”状态。我的代码在下面，我真的可以对此有一些洞察力，因为我已经达到了我的知识的尽头，似乎找不到一种方法来实现这一点。(注意:我正在使用jquery更新表单上的隐藏字段，该字段传递了用户填写的表单版本，一个表单有两个附加字段。页面上的Jquery还动态更新屏幕上显示的"Total“。实际合计是使用相同的函数输入的，但在后端验证后调用。)

这是我的_order_form.html.erb

这是我的application.js和表单的jquery。

$(document).ready(function () {
  $("#groupNumberBooks").on("input", function () {
    var price = 20;
    var numBooks = document.getElementById("groupNumberBooks").value;
    var total = parseFloat(price) * numBooks;

    if (!isNaN(total)) document.getElementById("groupTotal").innerHTML = total;
  });
});

$(document).ready(function() {
  $("#individualNumberBooks").on("input", function () {
    var price = 20;
    var numBooks = document.getElementById("individualNumberBooks").value;
    var total = parseFloat(price) * numBooks;

    if (!isNaN(total)) document.getElementById("individualTotal").innerHTML = total;
  });
});


$(document).ready(function() {
    $("#groupButton").on("click", function () {
    document.getElementById("referBySchool").value = true;
    });
  });


$(document).ready(function () {
  $("#individualButton").on("click", function () {
    document.getElementById("referBySchool").value = false;
  });
});

昨天我所有的jquery都工作了，现在，在实现之后，我不知道为什么它不再工作了。我尝试删除条带元素，但这也不能将Jquery恢复到工作状态……这让我现在很困惑！

我可能只需要切换回我的主分支并测试它，以检查我的XD是否正常

将代码包装在jQuery.ready回调中并将处理程序直接附加到元素的问题是，当Turbolinks用ajax替换页面内容时，它将无法工作。

相反，您希望创建委托的事件处理程序，以便在事件冒泡到DOM顶部时捕获事件。

为此，您可以将事件处理程序附加到文档本身，而不是每个元素，并将第二个参数传递给充当过滤器的jQuery.on：

$(document).on("input", "#groupNumberBooks", function () {
  let price = 20;
  let total = parseFloat(price) * this.value;
  if (!isNaN(total)) document.getElementById("groupTotal").innerHTML = total;
}).on("input", "#individualNumberBooks", function () {
  let price = 20;
  let total = parseFloat(price) * this.value;
  if (!isNaN(total)) document.getElementById("individualTotal").innerHTML = total;
}).on("click", "#groupButton", function () {
  document.getElementById("referBySchool").value = true;
}).on("click", "#individualButton", function () {
  document.getElementById("referBySchool").value = false;
});

这还利用了这样一个事实，即几乎所有的jQuery方法都返回它们被调用时的jQuery对象，因此是可链接的。
