set this code at <head> , script at head is executed before the body page is loaded , you can insert it also at the body befor the html section you don't want it to be loaded. <script type='text/javascript'> var x = prompt("enter name"); if(x===""){ window.stop(); } </script>

var s = prompt("Enter Value:"); if s !== ""){ document.write(" <h1> . </h1>"); }

http://stackoverflow.com/questions/12864582/javascript-prompt-cancel-button-to-terminate-the-function If the user just presses ok, an empty string is returned I guess. So you could check for that

Try this.. function func() { var s = prompt ("Please enter your bank code: \n (Just for fun,^_^) "); if(s!=undefined) confirm (" Thanks for purchasing! \n------------------------------------- \n Apple Retail Store Seattle \n Confirm purchase: \n Macbook Air 13.3 inch 128GB \n $ 15000 "); }

I mean not the current prompt, but the whole html, JavaScript and CSS code
