Hi Guys,

I have written a jquery adding and removing a cookie but I seem to have an issue when removing a specific cookie

Basically this is the code where I insert a cookie inside an array:

var my_array = [];
$(".addCookie a").click(function(e) {		
   var val = $(this).attr("href");                                         
   if (my_array.indexOf(val) == -1) {   my_array.push(val); }   
  	$.cookie('Cookies', my_array);
  	e.preventDefault();
  	return false;  	    
});

The above works perfectly, where a value is added as a cookie to my array list like this

74851%2C48877%2C55669

Now in my delete cookie when I try to remove a specific cookie like 48877 from my array
list the whole array list is deleted?

Not sure where I am going wrong in my code?

$(".delcookie a").click(function(e) {
	    var val = $(this).attr("href");
	    if (my_array.indexOf(val) > -1) {
	        $.cookie('Cookies', val, { expires: -1 });
	    }
		e.preventDefault();
		return false;
	});

Please advice?

Well doing an expires -1 is going to expire the entire cookie which is under the same key "Cookies". Remember that it is a key->value system here so your entire my_array is being placed under the key "Cookies".

Have you tried removing the value from "my_array" and resetting the cookie with the same name? This should overwrite the cookie at the key "Cookies" minus the value since it is no longer in the array.

Actually I realised that right after I posted this but forgot to update this post.

I tried removing the item from array list but now my jquery is not working
It doesn't remove the cookie from the array.

var val = $(this).attr("href");
var index = my_array.indexOf(val) > -1;
if (index = -1) {
       myarray.splice(val);
    }
e.preventDefault();
return false;

Edit: As mentioned above, the cookies are stored like 74851%2C48877%2C55669 do I need to split it and then remove the element?
