How to write line breaks in js

Newline in JavaScript

In JavaScript, newline characters can be represented in the following ways:

  • \n: Unix-style line feed (LF)
  • \r: Windows-style line feed (CR)
  • \r\n: Windows-style line breaks (CRLF)

Typically, use the Matching newlines. For example, on Unix systems, use \n, and on Windows systems, use \r\n.

Using newlines in strings

To insert newlines into a string, you can use the following syntax:

<code class="javascript">let myString = "这是\n多行\n字符串";</code>

In the above example , the newline character \n divides the string into three lines.

Using line breaks in text areas

To insert line breaks into text areas, you can use the following methods:

  • .value attribute: Assign the newline character directly to the .value attribute. For example:
<code class="javascript">myTextArea.value = "这是\n多行\n文本";</code>
  • ##.innerHTML Attribute: Use the HTML
    tag to insert line breaks. For example:
<code class="javascript">myTextArea.innerHTML = "这是<br>多行<br>文本";</code>

Note:

    Make sure to use the correct line break type, otherwise you may have display issues.
  • In multiline strings, each line should contain a newline character at the end.
  • If you are writing cross-platform code, consider using Node.js's
  • os module to get newlines that match your system.
