var t = 'some sting characters ktestvarj';

var variables = {
  'testvar': 123,
  'testvar1': 456
};

function replacer(match, p1, offset, string) {
  return variables[p1];
}

var modify = function (str) {
  var teststr = str.replace(/k(.*?)j/g, replacer);
  console.log(teststr); 
}

modify(t);
modify('some ktestvarj sting characters ktestvarj ktestvar1j');
