html - JavaScript Form Submit - Confirm or Cancel Submission Dialog Box

For a simple form with an alert that asks if fields were filled out correctly, I need a function that does this:

• Shows an alert box when button is clicked with two options:

  
  
  
  
  
  • If "OK" is clicked, the form is submitted
  
  
  • If cancel is clicked, the alert box closes and the form can be adjusted and resubmitted
  
  
  

I think a JavaScript confirm would work but I can't seem to figure out how.

The code I have now is:

function show_alert() {

  alert("xxxxxx");
}
