Somply you can use this :

var s='This is a demo from "Java script". This Demo uses "Regex"';
var reg=/\"(.*?)\"/g;
var result=s.match(reg).join('+').replace(/"/g,"");
console.log(result);

OR

You can use something like this :

var s='This is a demo from "Java script". This Demo uses "Regex"';
var reg=/\"(.*?)\"/g;
var result="";
s.match(reg).forEach( function(a){  
                                   if(result!="")
                                        result+="+";
                                    result+=a.replace(/\"/g,"");
                                   });

console.log(result);

You can use:

var s = 'This is a demo from "Java script". This Demo uses "Regex"';
var r = s.match(/"([^"]*)"/g).join('+');
//=> "Java script"+"Regex"

UPDATE:

s.replace(/.*?"([^"]*)"([^"]*)/g, function($0, $1, $2) {return $2!=""? $1+'+':$1});
//+> Java script+Regex
