Hi i have this simple code:
preg_replace('/[\r\n]+/', '</br>',$string);
i would like to replicate the same codein JS so i do:
string.replace('/[\r\n]+/','</br>');
but this won't work.
Also i would like to make it recursive using g , is it possible?
Thanks
replace() accepts a first parameter of type RegExp and you are passing a string, you need to change to:
string.replace(/[\r\n]+/,'</br>');
Also, replace() isn't a static method, in other words you don't call it like this. Instead you call it on the string on which you want to perform the replacement.
If you want to use g then you can:
string.replace(/[\r\n]+/g,'</br>');
^
string.

In JavaScript, .replace supports both strings and regexes as what to replace. You sent it a string, it doesn't know it's a regex. It was looking for the literal string '/[\r\n]+/'.
You need to use a regex literal:
string.replace(/[\r\n]+/g,'</br>');
Yes, you can use use regexes like that, with no quotes!
You can use the new RegExp constructor if you want to use a string as your regex:
string.replace(new RegExp('/[\r\n]+/', 'g'),'</br>');
