Yes. You can loop through the entire length of a string and increment a counter each time it finds a match.

var myStr = "foo";
var matchChar = "o";

var matchCounter = 0;

for (i = 0; i < myStr.length; i++) {
   if (myStr.charAt(i) == matchChar) {
      matchCounter++;
      }
   }

alert(matchCounter)
