Answer 3

Quick question, can the user type in a number with more than one digit?If so, the code is going to be much more complex.

Answer 4

No john he can type multiple numeric values but cannot type any letter

Answer 5

#Dick, thanks for your reply, but this alert is everytime showing when someone use different numeric values instead of 1,2,3. I want he can use all numeric values but can't type letters and other symbol

Answer 6

Heres the correct code Sandeep,

var input = prompt("Please type 1,2 or any other number");
if(input == null){

}else if (input == 1) {
document.write("<h1>HTML Tutorial");
} else if (input == 2) {
document.write("<h1>CSS Tutorial</h1>");
} else{
validate:
for(var k=0; k<input.length;k++){
switch (input[k]){
case "0":
case "1":
case "2":
case "3":
case "4":
case "5":
case "6":
case "7":
case "8":
case "9":
if(k == input.length - 1){
document.write("<h1>Javascript Tutorial</h1>");
break validate;
}else{
continue ;
}

default :
alert ("Enter only numerical values!");
break validate;
}
}
}

Answer 11

I am not sure I get your question properly but I guess this is what you mean,

function getInput(){
var input = prompt("Please type 1,2 or any other number");
if(input == null){

}else if (input == 1) {
document.write("<h1>HTML Tutorial");
} else if (input == 2) {
document.write("<h1>CSS Tutorial</h1>");
} else{
validate:
for(var k=0; k<input.length;k++){
switch (input[k]){
case "0":
case "1":
case "2":
case "3":
case "4":
case "5":
case "6":
case "7":
case "8":
case "9":
if(k == input.length - 1){
document.write("<h1>Javascript Tutorial</h1>");
break validate;
}else{
continue ;
}

default :
alert ("Enter only numerical values!");
getInput();
break validate;
}
}
}
}
getInput();
