Question

I have this HTML:

<form action="mypage.php" method="post"
   onsubmit="return confirm('Are you sure you want to submit this form? Submitting this form has serious consequences and you should definitely think long and hard before doing it.');">

I want to keep my code at or below 80 characters wide. How can I split this up into multiple lines while retaining the exact same functionality?

Answer 1

I’ld create a Javascript section that defines a function that you call from the form:

<script type="text/javascript">
    function formSubmit() {
         return confirm('Are you sure you want to submit this form? Submitting' +
                        ' this form has serious consequences and you should ' +
                        'definitely think long and hard before doing it.');
    }
</script>

the form:

<form action="mypage.php" method="post" onsubmit="formSubmit()">

This gets your Javascript out of you HTML form and can be clearly broken where you like.
