'Uppercase first letter of variable
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:
toUpperCase();
And had no luck, as it uppercases all letters.
Solution 1:[1]
Much easier way:
$('#test').css('textTransform', 'capitalize');
I have to give @Dementic some credit for leading me down the right path. Far simpler than whatever you guys are proposing.

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)

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'));

I imagine you could use substring() and toUpperCase() to pull out the first character, uppercase it, and then replace the first character of your string with the result.
myString = "cheeseburger";
firstChar = myString.substring( 0, 1 ); // == "c"
firstChar.toUpperCase();
tail = myString.substring( 1 ); // == "heeseburger"
myString = firstChar + tail; // myString == "Cheeseburger"
I think that should work for you. Another thing to consider is that if this data is being displayed, you can add a class to its container that has the CSS property "text-transform: capitalize".
Solution 5:[5]
To do this, you don't really even need Javascript if you're going to use
$('#test').css('text-transform', 'capitalize');
Why not do this as CSS like
#test,h1,h2,h3 { text-transform: capitalize; }
or do it as a class and apply that class to wherever you need it
.ucwords { text-transform: capitalize; }
Solution 6:[6]
It is as simple as the following:
string = 'test';
newString = string[0].toUpperCase() + string.slice(1);
alert(newString);
Solution 7:[7]
Ever heard of substr() ?
For a starter :
$("#test").text($("#test").text().substr(0,1).toUpperCase()+$("#test").text().substr(1,$("#test").text().length));
[Update:]
Thanks to @FelixKling for the tip:
$("#test").text(function(i, text) {
return text.substr(0,1).toUpperCase() + text.substr(1);
});

Building on @peter-olson's answer, I took a more object oriented approach without jQuery:
String.prototype.ucwords = function() {
return this.toLowerCase().replace(/\b[a-z]/g, function(letter) {
return letter.toUpperCase();
});
}
alert("hello world".ucwords()); //Displays "Hello World"
Example: http://jsfiddle.net/LzaYH/1/

Simplest way
let str="hiren raiyani"
str.toLowerCase().replace(/(?<= )[^\s]|^./g, a => a.toUpperCase());
user-defined function:
function capitalize(str){
return str.toLowerCase().replace(/(?<= )[^\s]|^./g, a => a.toUpperCase());
}
output: Hiren Raiyani
Use code as your user-defined function or direct

var mystring = "hello World"
mystring = mystring.substring(0,1).toUpperCase() +
mystring.substring(1,mystring.length)
console.log(mystring) //gives you Hello World
Solution 11:[11]
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
Solution 12:[12]
You can try this simple code with the features of ucwords in PHP.
function ucWords(text) {
return text.split(' ').map((txt) => (txt.substring(0, 1).toUpperCase() + txt.substring(1, txt.length))).join(' ');
}
ucWords('hello WORLD');
It will keep the Upper Cases unchanged.
Solution 13:[13]
Based completely on @Dementric 's answer, this solution is ready to call with a simple jQuery method, 'ucwords'... Thanks to everyone who contributed here!!!
$.extend({
ucwords : function(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
}
});
EXAMPLE: This can be called using the method
var string = "this is a test";
string = $.ucwords(string); // Returns "This Is A Test"
Solution 14:[14]
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());
});
Note: It's only change visual representation of the string. If you alert this string it's always show original value of the string.
Solution 15:[15]
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
Solution 16:[16]
Use below function
const capitalize = (s) => {
if (typeof s !== 'string') return ''
return s.charAt(0).toUpperCase() + s.slice(1)
}
capitalize('test') //'Test'
capitalize('name') //'Name'
Solution 17:[17]
Short and simple answer:
let str = 'this is a string';
let result = str.replace(/\b\w/g, x => x.toUpperCase());
console.log(result); // This Is A String
Solution 18:[18]
The string to lower before Capitalizing the first letter.
(Both use Jquery syntax)
function CapitaliseFirstLetter(elementId) {
var txt = $("#" + elementId).val().toLowerCase();
$("#" + elementId).val(txt.replace(/^(.)|\s(.)/g, function($1) {
return $1.toUpperCase(); }));
}
In addition a function to Capitalise the WHOLE string:
function CapitaliseAllText(elementId) {
var txt = $("#" + elementId).val();
$("#" + elementId).val(txt.toUpperCase());
}
Syntax to use on a textbox's click event:
onClick="CapitaliseFirstLetter('TextId'); return false"
Solution 19:[19]
I have used this code -
function ucword(str){
str = str.toLowerCase().replace(/(^([a-zA-Z\p{M}]))|([ -][a-zA-Z\p{M}])/g, function(replace_latter) {
return replace_latter.toUpperCase();
}); //Can use also /\b[a-z]/g
return str; //First letter capital in each word
}
var uc = ucword("good morning. how are you?");
alert(uc);

Html:
<input class="capitalize" name="Address" type="text" value="" />
Javascript with jQuery:
$(".capitalize").bind("keyup change", function (e) {
if ($(this).val().length == 1)
$(this).val($(this).val().toUpperCase());
$(this).val($(this).val().toLowerCase().replace(/\s[\p{L}a-z]/g, function (letter) {
return letter.toUpperCase();
}))
});
Solution 21:[21]
var str = "HELLO WORLD HELLO WORLD HELLO WORLD HELLO WORLD";
str = str.replace(
/([A-Z])([A-Z]+)/g,
function (a, w1, w2) {
return w1 + w2.toLowerCase();
});
alert(str);

Here is unicode-safe ucwords() function, which additionally respects double-lastnames like Russian ????-?????? and some noble names like Honoré de Balzac, d'Artagnan, Vincent van Gogh, Otto von Bismarck, Sulaym?n ibn D?w?d, etc:
String.prototype.ucwords = function() {
return this.toLowerCase()
.replace(/(^|\s|\-)[^\s$]/g, function(m) {
return m.toUpperCase();
})
// French, Arabic and some noble names...
.replace(/\s(Of|De|Van|Von|Ibn|??|???|???|???)\s/g, function(m) { // Honoré de Balzac, Vincent van Gogh, Otto von Bismarck, Sulaym?n ibn D?w?d etc.
return m.toLowerCase();
})
.replace(/(^|\s)(D|?)(['’][^\s$])/g, function(m, p1, p2, p3) { // D'Artagnan or d'Artagnan / ?’???????? ??? ?’????????
return p1 + (p1 === "" ? p2/*.toUpperCase()*/ : p2.toLowerCase()) + p3.toUpperCase();
});
}

Easiest Way to uppercase first letter in JS
var string = "made in india";
string =string .toLowerCase().replace(/\b[a-z]/g, function(letter){return letter.toUpperCase();});
alert(string );
Result: "Made In India"
Solution 24:[24]
var country= $('#country').val();
var con=country[0].toUpperCase();
ctr= country.replace(country[0], con);
no need to create any function just jugaaar
Solution 25:[25]
There sure are a lot of ways to do this!
One thing that I think people forget is that strings are arrays of characters. So, the first letter of any string will be the 'zeroth' element of its array:
let word = 'interesting';
console.log(word[0]);
// 'i'
The simplest way to take advantage of this fact for the purpose of uppercasing the first letter (afaik) would be:
let word = 'interesting';
let titleCase = word[0].toUpperCase() + word.substr(1);
console.log(titleCase);
// 'Interesting'
...or as a function:
function toTitleCase(word) {
return word[0].toUpperCase() + word.substr(1);
}
Solution 26:[26]
I think, the method should not convert any other letters than just the very first or the very first of any letter.
My solution for that are the following regexes:
function capitalize( str ){
return str.replace(/^\w/, (s) => s.toUpperCase() );
}
function capitalizeAll( str ){
return str.replace(/(\b\w)/g, (s) => s.toUpperCase() );
}
let test = 'hello world';
capitalize( test ); // Hello world
capitalizeAll( test ); // Hello World
