javascript - 如何从字符串中删除所有换行符(How to remove all line breaks from a string)

Question

I have a text in a textarea and I read it out using the .value attribute.

(我在textarea中有一个文本，并使用.value属性将其读出。)

Now I would like to remove all linebreaks (the character that is produced when you press Enter ) from my text now using .replace with a regular expression, but how do I indicate a linebreak in a regex?

(现在，我想使用正则表达式.replace从我的文本中删除所有换行符（按Enter时产生的字符），但是如何在正则表达式中指示换行符？)

If that is not possible, is there another way?

(如果那不可能，还有另一种方法吗？)

Answer 1

How you'd find a line break varies between operating system encodings.

(换行符的查找方式因操作系统编码而异。)

Windows would be \r\n , but Linux just uses \n and Apple uses \r .

(Windows将是\r\n ，但是Linux仅使用\n而Apple使用\r 。)

I found this in JavaScript line breaks :

(我在JavaScript换行符中发现了这一点：)

someText = someText.replace(/(
|
|
)/gm, "");

That should remove all kinds of line breaks.

(那应该删除所有换行符。)
