如何在转义字符串中用<br>替换\\ n？

Question

I know similar questions have been asked before. In all the ones I am aware of I did not find a solution, and I have already tried several things on my own which I do not list for the sake of brevity.

In Angular I am trying to replace \\n with <br> in an escaped string which looks like ABC\\nDEF\\n\\nGHI .

I am using var replaced = original.replace(/\\r?\\n|\\r/g, "<br>") which works fine if original has not been escaped.

How can I obtain the same when original has been escaped?

Answer 1

Since your string is escaped, you need to match literal backslashes.

Here is how you can match the linebreaks now:

var replaced = original.replace(/(?:\\r\\n|\\r|\\n)/g, "<br>");

In a literal notation, a double backslash matches a literal backslash.

Answer 2

I might be misunderstanding the question, but wouldn't

var result = escaped.replace(/(\n)/g, '<br>');

Do the trick?
