Uppercase first letter of variable

Question

I have searched over the web can can\'t find anything to help me. I want to make the first letter of each word upper case within a variable.

So far i have tried:

Answer 1

just wanted to add a pure javascript solution ( no JQuery )

function capitalize(str) {
  strVal = '';
  str = str.split(' ');
  for (var chr = 0; chr < str.length; chr++) {
    strVal += str[chr].substring(0, 1).toUpperCase() + str[chr].substring(1, str[chr].length) + ' '
  }
  return strVal
}

console.log(capitalize('hello world'));
