Question

提问by EZ-C

Example:

例子：

var i = 'Hello \n World'
console.log(i)

Would return:

会返回：

Hello
World

and I want it to return

而且我希望它返回

Hello \n World

not rendering the new line, as I intend to store this in a database.

不呈现新行，因为我打算将其存储在数据库中。

FOR THOSE WHO WANT TO STORE \n in Database

对于那些想要在数据库中存储 \n 的人

You don't need to escape, as your Document Database will do JSON.stringify, I use ArangoDB and it works perfectly fine, thanks to @PaulPro

你不需要逃避，因为你的文档数据库会做 JSON.stringify，我使用 ArangoDB 并且它工作得很好，感谢@PaulPro

Answer 1

You would escape the \with \\, which would tell the interpreter just to produce the character without processing it as a special character:

您将转义\with \\，它会告诉解释器只生成字符而不将其作为特殊字符处理：

var i = 'Hello \n World';
console.log(i)

Here are all the string escape codes:

以下是所有字符串转义码：

Answer 2

Escape \nwith \\nand store the string in DB. However, only \ncan also be stored in DB.

逃生\n用\\n并存储在数据库中的字符串。但是，\n也只能存储在DB中。

Answer 3

Use "\\n" instead of "\n" for this to work, same case with selenium java

使用 "\\n" 而不是 "\n" 使其工作，与 selenium java 相同的情况

      WebElement searchBox = driver.findElement(By.name("q"));
      searchBox.sendKeys("Test \n");
      searchBox.submit();
