如何在脚本中添加新行

Question

你好我不知道我的标题是否有帮助，但这里是我的问题我想在JS，CSS，HTML中做一个类型编写器效果，除了当我尝试添加一条不显示的新行时，添加一行新文本。

\t var str = "<p>I want to put text here then another line under this one</p>", 
 
\t <!--var str = "<p>text here</p>",--> <!--This is what I tried to do to add a new line--> 
 
    i = 0, 
 
    isTag, 
 
    text; 
 

 
(function type() { 
 
    text = str.slice(0, ++i); 
 
    if (text === str) return; 
 
    
 
    document.getElementById('typewriter').innerHTML = text; 
 

 
    var char = text.slice(-1); 
 
    if(char === '<') isTag = true; 
 
    if(char === '>') isTag = false; 
 

 
    if (isTag) return type(); 
 
    setTimeout(type, 80); 
 
}());

#typewriter { 
 
\t \t color: lime; 
 
\t \t text-align: center; 
 
\t }

<div id="typewriter"></div>

Answer 1

使用<br />

var str = "<p>I want to put text here<br /> then another line under this one</p>"; 

Answer 2

var str = "My text\nSome more text"; 
 
var stra = str.split(""); 
 
var tw = document.getElementById("output"); 
 
function type(){ 
 
    var char = stra.shift(); 
 
    if (char){ 
 
     tw.innerHTML += char; 
 
     setTimeout(type, 80); 
 
    } 
 
    
 
} 
 
type();

<pre id="output"></pre>

Answer 3

另一种可能性是使用组段落元件0并将span的显示样式属性添加到block。

window.onload = function() { 
 
    var str = "<p><span>I want to put text here then another line under this one</span><span>text here</span></p>"; 
 

 
    (function type(isInTagArg, indexArg) { 
 
    var index = indexArg || 0; 
 
    if (index >= str.length) 
 
     return; 
 

 
    var isInTag = isInTagArg || false; 
 
    if (isInTag == false) { 
 
     if (str.charAt(index) == '<') { 
 
     return type(true, index + 1); 
 
     } else { 
 
     document.getElementById('typewriter').innerHTML = str.substr(0, index + 1); 
 
     } 
 
    } else { 
 
     if (str.charAt(index) == '>') { 
 
     return type(false, index + 1); 
 
     } 
 
     return type(true, index + 1); 
 
    } 
 
    setTimeout(function() {type(false, index + 1)}, 80); 
 
    }()); 
 
}

#typewriter { 
 
    color: lime; 
 
    text-align: center; 
 
} 
 
#typewriter span 
 
{ 
 
    display: block; 
 
}

<div id="typewriter"></div>
