I want to make the first letter in a text box to be capital but i have no idea on how i can apply it. e.g sitholimela ----> Sitholimela
I want to apply this to a text box.
Thanks for your help.

<input type="text" id="targetBox">
var capitalize = function(e){
// if the first letter is lowercase a-z
// ** don't run the replace unless required, to permit selecting of text **
if(this.value.match(/^[a-z]/)){
// replace the first letter
this.value = this.value.replace(/^./,function(letter){
// with the uppercase version
return letter.toUpperCase();
});
}
}
// listen to key up in case of typeing, or pasting via keyboard
// listen to mouseup in case of pasting via mouse
// prefer `up` events as the action is complete at that point
document.getElementById('targetBox').addEventListener('keyup', capitalize);
document.getElementById('targetBox').addEventListener('mouseup', capitalize);
Please try this. It works.
