Putting put string text in javascript raise syntax error

[mstdmstd]

Hello,

In my Laravel 8 / jQuery 3.5.1 app I need to put string text in javascript like :
 

L.marker([{{$adLocation->lat}}, {{ $adLocation->lng }}]).addTo(locationMap)
.bindPopup("<b>Add Location!</b><br />"+'{!! crlf($adLocation->content) !!}'+".").openPopup();

I try to replace crlf characters with method like

function crlf(string $s) : string
{
return str_replace( array("\r\n", "\r", "\n"), "<br />", $s);

// 2 lines below does not work too
// return preg_replace('/\<br(\s*)?\/?\>/i', "\n", $s);
// return nl2br($s);
}

But anyway I got error :

edit:539 Uncaught SyntaxError: Invalid or unexpected token

and I see in browser : https://prnt.sc/wtpnri and https://prnt.sc/wtq78t

Which way is valid ?

Thanks!

Normal Javascript strings do not work across multiple lines.

If you're putting a value into Javascript then use @json instead. You should basically never ever use {!! for anything.

Well, if to work the line on server, which methods have I to use?

I can't tell what you were trying to ask, but I think the answer is still what I said before.
