Re-do a function if condition is met

Question

Hi Guys,

I've just gone through the basic programming parts and I just wanted to make a simple little text game. For fun, get's me used to writing a few things.

In the below code, if the 'else' statement is triggered I want them to have to re-do the prompt.

var concent = prompt("Would you like to go on an adventure?");
if(concent == "yes"){
    alert("That's great news! Let's get started.");
} else if(concent == "no"){
    alert("Oh that's a shame, I guess I'll have to look for someone else..");
} else {
    alert("I dont know what you mean by that answer. Try again!");
}

How would I go about doing this?

Hi Vaughan,

I think you are looking to repeat the prompt and you could use recursion via procedure like .....

<script type="text/javascript">

function ask_prompt(){

  var concent = prompt("Would you like to go on an adventure?");

  if(concent == "yes"){
      alert("That's great news! Let's get started.");
  } else if(concent == "no"){
      alert("Oh that's a shame, I guess I'll have to look for someone else..");
  } else {
      alert("I dont know what you mean by that answer. Try again!");
      ask_prompt();
  }  

}

ask_prompt();

</script>

Hope this helps...

Thank you very much.

Could you possibly explain what the 'ask' does?

ask_prompt is just a function name. and i just called it at the last so when browser loads file it will execute it first time.

@Vaughan - You should review how functions work in JavaScript
