Convert lowercase letter to upper case in javascript

Question

I have a code that will convert lower case letters to uppercase but it works only with IE and not in Crome or Firefox.

function ChangeToUpper()
  {         
         


        

Answer 1

Have you tried this?

var myString = "this is a String";
alert(myString.toUpperCase()); // "THIS IS A STRING"
alert(myString.toLowerCase()); // "this is a string"

Thanks... Hope you like it.
