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

var mystring = "hello World"
mystring = mystring.substring(0,1).toUpperCase() + 
mystring.substring(1,mystring.length)

console.log(mystring) //gives you Hello World

Answer 2

var ar = 'foo bar spam egg'.split(/\W/);
for(var i=0; i<ar.length; i++) {
  ar[i] = ar[i].substr(0,1).toUpperCase() + ar[i].substr(1,ar[i].length-1) 
}
ar.join(' '); // Foo Bar Spam Egg

Answer 3

var country= $('#country').val();

var con=country[0].toUpperCase();

ctr= country.replace(country[0], con);
   

no need to create any function just jugaaar

Answer 4

Without JQuery

String.prototype.ucwords = function() {
    str = this.trim();
    return str.replace(/(^([a-zA-Z\p{M}]))|([ -][a-zA-Z\p{M}])/g, function(s){
        return s.toUpperCase();
    });
};

console.log('hello world'.ucwords()); // Display Hello World

Answer 5

http://phpjs.org/functions/ucwords:569 has a good example

function ucwords (str) {
    return (str + '').replace(/^([a-z])|\s+([a-z])/g, function ($1) {
        return $1.toUpperCase();
    });
}

(omitted function comment from source for brevity. please see linked source for details)

EDIT: Please note that this function uppercases the first letter of each word (as your question asks) and not just the first letter of a string (as your question title asks)

Answer 6

You can use text-transform: capitalize; for this work -

HTML -

<input type="text" style="text-transform: capitalize;" />

JQuery -

$(document).ready(function (){
   var asdf = "WERTY UIOP";
   $('input').val(asdf.toLowerCase());
});

Try This

Note: It's only change visual representation of the string. If you alert this string it's always show original value of the string.
