Replacing newline character in javascript

I am trying to replaces instances of \r or \n characters in my json object with <br /> for display on a website.

I tried:

myString = myString.replace("\\r?\\n", "<br />");

But this doesn't seem to do anything. When I replace the regex with somet开发者_如何转开发hing else (like "a" for instance, the replace works as expected). Any ideas why this isn't working for the newline chars?

Try this:

myString = myString.replace(/[\r\n]/g, "<br />");

Update: As told by Pointy on the comment below, this would replace a squence of \r\n with two <br />, the correct regex should be:

myString = myString.replace(/\r?\n/g, "<br />");

CSS:

 white-space: pre-wrap;

Is a far more eficient method.

try replace(/\r\n|\n/, '<br />')

This worked for me:

str = str.replace(/\\n|\\r\\n|\\r/g, '<br/>');

Using double slash
