javascript确认不会停止提交表单

Question

i am trying to do a confirm function using javascript in php which it worked only in showing the buttons but whatever you press the form will submit heres the code and the function

<form action='Allocated.php' method='post'  >
    <input type='submit' name='disc' value='Discontue Asset'    formnovalidate='formnovalidate' onclick='myFunction()' />
    <input type='hidden' name='alloc' value='$AllocID' />
    </td>
</form>

and the function

function myFunction() {
    var r = confirm("Press a button!");
    if (r == true) {
        return true;
    } else {
        return false;
    }
}

any help would be appreciated THanks

Answer 1

Change onclick='myFunction()' to onsubmit='return myFunction()' so that the returned value from the function can be returned to the event.
