提示后javascript显示用户输入 [英] javascript displaying user input after a prompt
问题描述
我想显示用户输入完信息后输入的内容.当用户到达最后一个提示时，我希望页面显示他们输入的内容.例如:如果他们在名称部分下输入了apples，我希望它在代码底部的P1部分列出apples一词.我是javascript的新手，并且我事先知道我的代码不稳定，但是我正在学习，所以请放轻松，请帮助我弄清楚在javascript完成后如何显示用户输入.
I am wanting to display what the user entered after the user has finished inputting in information. When the user gets to the last prompt I want the page to display what they entered in. For example: if they entered in apples under the name portion I want it to list the word apples in the P1 section of my code at the bottom. I am new to javascript and in advance, I know my code is choppy but I am learning so please go easy on me and please help me figure out how to display user-input after the javascript has finished.
我的代码:

<script type="text/javascript">
var user = prompt("Welcome to learning about allocations with me, mr fields.

switch(user){
case 'YES':
var user_1 = prompt("What's your name?");
switch(user_1) {
case 'Buster':
prompt("Hey, brother!");
break;
case 'Alex':
prompt("I've made a huge mistake.");
break;
case 'Steve':
prompt("Steve Holt!");

}

推荐答案
要在Javascript中显示变量的值，您需要将其作为DOM树中的节点之一添加到DOM(文档对象模型)中.这是一个简单的示例，供您玩耍和学习(下).
To print the value of the variable in Javascript you need to add it to the DOM (document object model) as one of the nodes in the DOM tree. Here is a simple example to play around with and learn (below).
重要提示:请检查HTML文档的结构也应正确.祝你好运.
IMPORTANT: please check how the HTML document should be properly structured as well. Good luck.
<!DOCTYPE html>
<html>
<head>
<title>This will display some answers</title>
<script type="text/javascript">
window.onload = function(){
var username = prompt("What is your name?");
var usernameElement = document.getElementById("name");
usernameElement.innerText = username;
}
</script>
</head>
<body>
<p id="name"></p>
