Question

我在这个大学任务中遇到了一个小问题。当用户输入他们的数据时，创建帐户ID号。我已经完成了这项工作，它的工作方式应该如此。但问题出在这里：用户点击提交按钮并创建帐户ID号后，他们输入的内容需要显示在其下方。赋值说我需要创建一个名为displayNewAccount的函数，并将其放入其他函数中。我放入createEventListeners函数。该文本需要在HTML页面上的自定义ID（account）中显示。输入第一个名称输入（fnameinput）的数据应显示在＆＃34; First Name＆＃34;之后。（fname）和姓氏输入（lnameinput）应在＆＃34;姓氏＆＃34;之后显示。（lname）等等。如果displayNewAccount函数必须在另一个函数内移动，那么这完全没问题。我已经在网上找了几个例子，但是我无法让它为我工作。我究竟做错了什么？谢谢你的帮助。

 }


 // Displays an account summary section when the "Create Account" button is clicked.
 function displayNewAccount() {
  document.getElementById("account").innerHTML = "First Name: " + fname + "<br>" + "Last Name: " + lname + "<br>" + "Address: " + addrinput + "<br>" + "City: " + cityinput + "<br>" + "State: " + stateinput + "<br>" + "Zip: " + zipinput + "<br>" + "Account ID: " + accountidbox;
 }

 if (window.addEventListener) {
  window.addEventListener("click", displayNewAccount, false);
 }
 else if (window.attachEvent) {
  window.attachEvent("onclick", displayNewAccount);
 }


}

if (window.addEventListener) {
 window.addEventListener("load", createEventListeners, false);
}
else if (window.attachEvent) {
 window.attachEvent("onload", createEventListeners);
}

提交后在同一表单页面上加载数据
