我正在尝试复制类似的内容，该页面接受用户输入的名称，例如名称，然后在下一页的句子中显示该名称

我已经编写了类似的代码，但是与我需要的不匹配。任何帮助或教程对此将不胜感激。

添加完整代码。我希望能够在秒钟提示中使用我的名字，例如“ Greg type a形容词”。但是我发现很难。

// List of prompts for the user
var prompts = [
	'Type your name',
	'Type an adjective',
	'Type a noun'
   ];

var answers=[];
// Keep track of current prompt we're on
var currentPrompt = 0;

// A function that will call the next prompt
var nextPrompt = function() {
  //if there's no answer in the form
  if (currentPrompt != 0){
    answers.push($('input').val());
  }
	// if there is a next prompt
	if (currentPrompt < prompts.length) {
		// put first prompt in all html elements with class 
		$('.prompt').html(prompts[currentPrompt] + '<br><input type="text">');
		// move the next prompt into variable currentPrompt 
		 
     currentPrompt = currentPrompt + 1;
	}

  


	//or else if we're at the end of the array
	else {
		// put a new message into the html.
		showFinal();
	
	}
}

//puts user answers into HTML
var showFinal = function() {
  $('.prompt').html('This is the story of <span class="fill">'+answers[0]+'</span> and the <span class="fill">'+answers[1]+'</span> <span class="fill">'+answers[2]+'</span>.');
  //and then hide the button
  	$('button').hide();
}
// run nextPrompt function when button is clicked
$('button').click(function() {
	nextPrompt();
});

// Show the first prompt as soon as js loads
nextPrompt();

body{
  text-align: center;
  font-family: 'Fjalla One';
  font-size: 20px;
  background: #e6eaf0;
  }
  
button{
  margin: 40px;
  }
  
input {
  font-size: 24px;
  }
  
.fill {
  background: white;
  color: red;
  border-bottom: 2px black solid;
  font-family: 'Shadows Into Light';
  padding: 0 6px;
  margin: 4px;
  }

嗯...有趣。

我设法按照您指定的方式在下面的代码段中获取代码。我添加{name}到第二个提示。调用该提示时，用户已经在上一个answers[0]设置中输入了他们的名称=>并且是用户名。因此，我置于if在nextPrompt()检查当前是否提示是第二个。如果是的话，我更换{name}的prompts[1]同answers[0]。相当愚蠢，但我希望您觉得它有用。
