Question

I am having an issue to replace "\r\n Departing\r\n " with "Departing" in javascript.

Please suggest best way to do this.

Answer 1

This should work:

"\r\n Departing\r\n ".replace(/[^a-z]/gmi,'');

g => global
m => multi-line
i => case-insesitive

[^a-z] => chars, a to z, but thanks to case-insensitivity A-Z are not replaced, either.

If numbers might occur in the string, you can prevent them from being replaced pretty easily:

"\r\n Departing2\r\n ".replace(/[^a-z0-9]/gmi,'');

If all you want to do is remove line-feeds and trim the remaining string:

"\r\n Departing2\r\n ".replace(/[\r\n]/gm,'').replace(/^\s+|\s+$/g,'');
"\r\n We're Departing, too\r\n!".replace(/[\r\n]/gm,'').replace(/^\s+|\s+$/g,'');

Should take care of things for you rather nicely
