Question

I am working on a shopping website and want to check if the item is present in the cart. If it exists, alert it's already in the cart and return false. If it doesn't exist add it to the cart.

I tried it like below, the code is working fine but the alert is looping.

$("#showBtn").focus();
msgBoxImagePath = "http://www.ournestonline.com/assets/images/";
function showMsgBox() {
    simpleCart.bind('beforeAdd', function (item) {
        if (simpleCart.has(item)) {
            alert("Already in the Cart");
            $.msgBox({
                title: "Shopping Cart",
                content: "Already in cart",
                type: "alert"
            });
            return false;
        } else {
            $.msgBox({
                title: "Shopping Cart",
                content: "Great Selection Your Item is Added to Cart Happy Shopping",
                type: "alert"
            });
        }
    }); 
}
