i am making an online multiple choice quiz for a school.
i am trying to make it so that when a student presses the submit button, it calls a javascript function that checks to see wether any questions were left blank
if they were, a confirmation box pops up asking if they want to continue or not
everything works great so far
if i choose to continue, i set it to do a document.forms[0].submit, which should send everything to my mysql database
however, the page just refreshes instead
my code:
javascript-
... code for confirmation...
if they press ok:
alert('You got '+ score + ' questions right. This score will now be submitted to the database');
document.forms[0].mark.value=score;
document.forms[0].submit();
form-
<form method="post" action="<?php echo $PHP_SELF?>">
...
...
...
<input type="button" name="done" onclick='javascript:Ras()'>
