Javascript loop with send event too fast?

[Ole Raptor]

I have a function that calls a php script to update cart items (cookie). When I have multiple items in the cart I use a loop that calls my function.

function updateCart(ur){
    $.ajax({
        url: ur,
        success: function(data){
            console.log(data);
        }
    });
}

I think this is firing too fast or something. When there is one item in the cart it works fine. When there are multiple items nothing updates but the function does get called.
Any help is greatly appreciated. Thank You

I have fixed this by changing to the xmlhttprequest. I was able to set the last object to false.

xmlhttp.open("GET","ajax_info.txt",false)

This took care of it.
