How to add carriage return to string in js

There are two ways to add a carriage return character in JavaScript: using the "\n" character or the String.fromCharCode(10) method. Use the "\n" character to insert a newline character directly into the string, and use the String.fromCharCode(10) method to convert Unicode code point 10 to a carriage return character.

How to add a carriage return to a JavaScript string

In JavaScript, you can use \n character or String.fromCharCode(10) method adds a carriage return to the string.

Using the \n characters

The easiest way is to use the \n characters directly in the string. This creates a newline character in the string, splitting the text into two lines. For example:

<code class="js">const str = "Hello\nWorld";
console.log(str); // 输出：Hello
//          World</code>

Use the String.fromCharCode(10) method

##String.fromCharCode(10) method to Converts a given Unicode code point to the corresponding character. The Unicode code point for carriage return is 10, so we can add carriage return using the following code:

<code class="js">const str = "Hello" + String.fromCharCode(10) + "World";
console.log(str); // 输出：Hello
//          World</code>

Example

The following is a string in JavaScript Specific example of adding a carriage return:

<code class="js">// 创建一个字符串
const str = "This is a long string";

// 使用 `\n` 字符添加回车
const newStr = str.replace("long", "long\nstring");

// 使用 `String.fromCharCode(10)` 方法添加回车
const anotherNewStr = str.substring(0, 10) + String.fromCharCode(10) + str.substring(10);

// 输出更改后的字符串
console.log(newStr); // 输出：This is a long
//                 string
console.log(anotherNewStr); // 输出：This is a
//                    long string</code>
