I'm a noob with jQuery...and I hope I've explained this well enough; I have a <ul> header that appears when I've added an entry to a dynamically created
list using $.post. Each entry added has a delete/edit button associated with it.
Header is this:
<ul class="header">
<li>Month</li>
<li>Year</li>
<li>Cottage</li>
</ul>
My dynamic
list that is created:
<ul class="addedItems">
<li>Month</li>
<li>Year</li>
<li>Cottage</li>
<li><span class="edit">edit</span></li>
<li><span class="del">delete</span></li>
</ul>
This all looks like this:
Month Year Cottage <--this appears after I've added an entry
-------------------------------- and I want it to stick around unless
all items are deleted.

My question is: Is there some kind of conditional that I can use with jQuery to hide the class="header" if all the items are deleted? I've read up on conditional statements like is and not with jq but I'm not really understanding how they work. All of the items in class="addedItems" is stored in data produced by JSON.
This is the delete function:
$(".del").live("click", function(){
var del = this;
var thisVal = $(del).val();
$.post("delete.php", { dirID : thisVal },
function(data){
if(confirm("Are you sure you want to DELETE this entry?") == true) {
if(data.success) {
//hide the class="header" here somwhere??
$(del).parents(".addedItems").hide();
} else if(data.error) {
// throw error if item does not delete
}
}
}, "json");
return false;
}); //end of .del function
Here is the delete.php
<?php
if($_POST) {
$data['delID'] = $_POST['dirID'];
$query = "DELETE from //tablename WHERE dirID = '{$data['delID']}' LIMIT 1";
$result = $db->query($query);
if($result) {
$data['success'] = true;
$data['message'] = "Entry was successfully removed.";
} else {
$data['error'] = true;
$data['message'] = "Item could not be deleted.";
}
echo json_encode($data);
}
?>
