use regex to add the $ before the numbers

alert("This 123 and if we add 2 in 123 than it becomes 125".replace(/(\s)(?![a-z A-Z]+)/g, " $"));

Try this 

var str = "This 123 and if we add 2 in 123 than it becomes";
var t = str.split(" ");
var c = 0;
var e = 0;
var d = "";
for (var i = 0; i < t.length; i++) {
  if (parseInt(t[i])) {
    d = d + " " + "$" + t[i]
    c += parseInt(t[i]);
    e = parseInt(t[i]);
  } else {
    d = d + " " + t[i]
  }

}
alert(d + " $" + (c - e))

var string = "This 123 and if we add 2 in 123 than it becomes 125.".replace(/([0-9]{1,9})/g, 
function(str){
	return "$"+str;
});
document.writeln(string);

You can do it like by using regex and replace's with its callBack signature,

var str = "This 123 and if we add 2 in 123 than it becomes 125";
str = str.replace(/\d+/g, function(v){
 return "$" + v;
});

console.log(str); //This $123 and if we add $2 in $123 than it becomes $125
