JavaScript Form Submit - Confirm or Cancel Submission Dialog Box

问题:

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:

A simple inline JavaScript confirm would suffice:

No need for an external function unless you are doing validation, which you can do something like this:

回答2:

function show_alert() {   if(confirm("Do you really want to do this?"))     document.forms[0].submit();   else     return false; }

OK, just change your code to something like this:

Also this is the code in run, just I make it easier to see how it works, just run the code below to see the result:

function submitForm() {   return confirm('Do you really want to submit the form?'); }

   submit
