HiI have to create a HTML/Javascript program which does the following things1. Uses one window prompts to allow the user to enter their Code_Id (which is between 1 and 15) into a variable called Code_Id.2. Uses a function which will accept the string values from a caller function, converts it to an integer (using parseInt), test to see if the Code_Id lies between 1 and 15 and outputs a alert box with an appropriate message to tell the user if the Code_Id is valid or not. . 3. Displays a message from the body of the program which thanks the user for entering their Code_Id. Now I ahve created the code below but the only this that seems to work it the promts box that asks for the Id can anyone please help!!!! :)Da Code

<html><head><title>Code ID Exercise</title><script language='JavaScript'>function ask(String_Id){  var valid = false;  var id  = 0      id = parseInt(String_Id);    document.write("hello");    if (id >= 1) && (id <= 15)    {      valid = true;    }    else    {      window.alert("The ID entered is invalid please enter again");    }}</script></head><body><script language='JavaScript'>  var Code_Id = window.prompt("Please enter your ID please","");       document.write(Code_Id);       ask(Code_Id);</script><h2>Thank you for entering your ID</h2></body></html>

try this

<html><head><script type="text/javascript">	onload=	function getCode()	{  var Code_Id = prompt('Please enter your code','');  var msg, html;  var objOutput = document.getElementById('divOutput');  objOutput.innerHTML = '';  if(isValid(Code_Id))  { 	 msg = 'Your code appears to be valid!'; 	 html = 'Thank you for entering your code';  }  else  { 	 msg = 'Your code is invalid!'; 	 html =  'Your code was invalid. ' +   	 'Click <a href="javascript:getCode()">here</a> to re-enter your code.';  }  alert(msg);  objOutput.innerHTML = html;	}	function isValid(ID)	{  var parseId = parseInt(ID);  if(parseId >= 1 && parseId <= 15) 	 return true;  else 	 return false;	}</script></head><body><div id="divOutput"></div></body></html>
