javascript replaces text on loop from separate strings

I made loop for, from split string and try to find some text and replace it by the result of separate string, here for example :

function replaceStr(str, find, replace) {
  for (var i = 0; i < find.length; i++) {
    str = str.replace(new RegExp(find[i], 'gi'), replace[i]);
  }
  return str;
}

var str = 'some text contain car and some house contain car, or car contain someone';
var values = "cat,dog,chicken";

splt = values.split(',');

for (i = 0; i < splt.length; i++) {
  var find = ['car'];
  var replace = ['' + values[i] + ''];
  replaced = replaceStr(str, find, replace);
}
console.log(replaced);
//console.log(splt.length);

but the result return zeros

I want find all "car" text and replace it from splited text by comma characters anyone can help me please..

I guess implicitly from your question you want to replace "car" with cat, dog, chicken progressively to achieve this: "some text contain cat and some house contain dog, or chicken contain someone"

So roughly this would be your solution:

var str = 'some text contain car and some house contain car, or car contain someone';
var values = "cat,dog,chicken";
var splt = values.split(',');
var replaced = str;
for (i = 0; i < splt.length; i++) {
  replaced = replaced.replace('car', splt[i]);  
}
console.log(replaced);

hum what is the goal of your replaceStr function ? maybe this is enough :

var str = 'some text contain car and some house contain car, or car contain someone';
var values = "cat,dog,chicken";

splt = values.split(',');

for (i = 0; i < splt.length; i++) {
   var find = 'car';
   str = str.replace(find, splt[i]);
}
console.log(str);
