Javascript changes date format?

nn4n4s · 03-19-2012, 05:38 PM

Hello.

I have got this kind of array:

Code:

$days = array('Monday' => '2012-03-19',
                    'Tuesday' => '2012-03-20'
                   );

I'm iterating like this:

Code:

foreach($days as $key => $value){
       echo '<a href="javascipt:confirmDelete('.$value.');">Delete</a>';
}

Script:

Code:

function confirmDelete(day)
{
	if (confirm('Delete?')) {
		window.location.href = 'processDay.php?action=delete&day=' + day ;
	}
}

While i hover over the link with coursor, it show it good: javascript:confirmDelete(2012-03-19), but when I submit the delete confirmation, i get &day=1987. Where is the problem?

2012-03-19 is a subtraction expression.

2012 minus 3 is 2009.

2009 minus 19 is 1990.

So I don't know why you get 1987 instead of 1990.

Now try putting quotes around your date.

Code:

foreach($days as $key => $value){
       echo '<a href="javascipt:confirmDelete(\''.$value.'\');">Delete</a>';
}

turn a php var into js using json_encode:

Code:

 echo '<a href="javascipt:confirmDelete('.  json_encode($value)  .');">Delete</a>';

oh, and by the way, confirm() is assertive, not inquisitive, so re-word your question to reflect ok/cancel instead of yes/no for best UX:

Code:

if (confirm('Deleting...')) {
