我只编程了大约一个月，我正在尝试将表单的输出放入表格中，所有这些都是我尝试用 Javascript 制作的。
我已经把它放进去了，但是当我点击按钮时它就消失了。
如何解决此问题，以便在单击后将文本永久保留在那里？
这是我的代码:
<html>
<head>
<meta charset="utf-8"/>
<title>Make a booking</title>
<link rel="stylesheet" href="booking_page.css"/>
<script type="text/javascript">
var headings = new Array();
headings[0] = "Your colleague";
headings[1] = "CLOSED";
headings[2] = "9:00";
headings[3] = "9:15";
headings[4] = "9:30";
headings[5] = "9:45";
headings[6] = "10:00";
headings[7] = "10:15";
headings[8] = "10:30";
headings[9] = "10:45";
headings[10] = "11:00";
headings[11] = "11:15";
headings[12] = "11:30";
headings[13] = "11:45";
headings[14] = "12:00";
headings[15] = "12:15";
headings[16] = "12:30";
headings[17] = "12:45";
headings[18] = "1:00";
headings[19] = "1:15";
headings[20] = "1:30";
headings[21] = "1:45";
headings[22] = "2:00";
headings[23] = "2:15";
headings[24] = "2:30";

最佳答案
preventDefault()阻止事件冒泡
function makeBooking(e){
e.preventDefault()
var aptTime = document.getElementById('apt_time').value;
var colleagueName = document.getElementById('col_name').value;
var aptBlock = document.getElementById(colleagueName + aptTime);
aptBlock.innerHTML = colleagueName + aptTime;
}
