How to make javascript prompt box cancel button to do nothing?

How can I make cancel button in javascript prompt box to do nothing like the cancel button on confirmation box instead of sending "null" values?

Or is it possible to remove the cancel button from the prompt box so there is only "ok" button left?

This is what I have tried but it still sends the null to value to my PHP file.

 function AskQuestion(data)
{
   var id = getUrlVars()["id"];
   console.log(data);
   if(data.key[0].status == "ok") {
      var reply = prompt(data.key[0].REPLY, "");
      var index = data.key[0].IND;
      if(reply != "" && reply !== null) {
      //do nothing
      }else{
      jQuery.ajax({ type: "POST",
                    url: serviceURL + "message.php",
                    data: 'id='+id+'&arvo='+reply+'&index='+index,
                    cache: false,
                    success: AskQuestion});
                    }
   } else {
     window.location = "page.html"
   }
}

You've got your test on the return value the wrong way around. As it is you // do nothing when the user enters text, and call ajax when they don't. Change

if(reply != "" && reply !== null) {
    // do nothing

to

if(reply == null || jQuery.trim(reply).length == 0) {
    // do nothing

You can just return to exit the function

A few ideas:

reply = jQuery.trim( prompt(...) || "" );
if( reply ){
  jQuery.ajax(...)
}
