Disabling this script when focused on a textarea

[shuban]

Code: [Select]

if (empty($gallerySettings['gallery_set_quickreply_full']))
{                 
echo "               
<script>           
document.onkeydown = checkKey;

function checkKey(e) {

e = e || window.event;

if (e.keyCode == '37') {
// left arrow
";       
if ($previousImage != $context['gallery_pic']['ID_PICTURE'])
echo  'document.location=\''.$scripturl, '?action=gallery;sa=prev;id=', $context['gallery_pic']['ID_PICTURE'], '\';';

echo " 
}
else if (e.keyCode == '39') {
// right
";       
if ($nextImage != $context['gallery_pic']['ID_PICTURE'])
echo  'document.location=\''.$scripturl, '?action=gallery;sa=next;id=', $context['gallery_pic']['ID_PICTURE'], '\';';

echo "       
}
}
</script>";
}
Is there a way from preventing this script from running when a textarea is highlight (onfocus)? Sometimes I will use left and right to move the cursor, and this changes the picture

There is a way with javascript but I do not know it without research
