Korak 1 :
Ta del kode vstavite v <head> del strani:

<SCRIPT LANGUAGE="JavaScript"> function convert(input) { var inputlength = input.length; input = input.toLowerCase(); var phonenumber = ""; for (i = 0; i < inputlength; i++) { var character = input.charAt(i); switch(character) { case '0': phonenumber+="0";break; case '1': phonenumber+="1";break; case '2': phonenumber+="2";break; case '3': phonenumber+="3";break; case '4': phonenumber+="4";break; case '5': phonenumber+="5";break; case '6': phonenumber+="6";break; case '7': phonenumber+="7";break; case '8': phonenumber+="8";break; case '9': phonenumber+="9";break; case '-': phonenumber+="-";break; case 'a': case 'b': case 'c': phonenumber+="2";break; case 'd': case 'e': case 'f': phonenumber+="3";break; case 'g': case 'h': case 'i': phonenumber+="4";break; case 'j': case 'k': case 'l': phonenumber+="5";break; case 'm': case 'n': case 'o': phonenumber+="6";break; case 'p': case 'q': case 'r': case 's': phonenumber+="7";break; case 't': case 'u': case 'v': phonenumber+="8";break; case 'w': case 'x': case 'y': case 'z': phonenumber+="9";break; } } document.myform.number.value = phonenumber; return true; } </script>
