SyntaxError: identifier starts immediately after numeric literal, str_replace variable to javascript

so i have this variable

$number = "1944/UN31/KEP/2017" then i want to replace the "/" to "" so i create new variable:

$number2 = str_replace("/","",$number) // the result would be : 1944UN31KEP2017

i can access my $number variable to js before using (in laravel blade):

onClick="doPrintTxtdaftar({{ $number}});">Print</a>

but when i replaced the string and the 2nd variable :

onClick="doPrintTxtdaftar({{ $number2}});">Print</a>

i got an error in my debuger saying : SyntaxError: identifier starts immediately after numeric literal

and its pointing out my 2nd varable value : 1944UN31KEP2017

can somebody pls help me… Thanks

Answer

Wrap with quotes

Change this:

onClick="doPrintTxtdaftar( {{$number}} )">Print</a>

to:

onClick="doPrintTxtdaftar( '{{$number}}' )">Print</a>

Hope this work for you !!!
