How to send js array object to laravel controller function using <a> tag in view?

I have cart functionality in my project where IDs of the items are stored in a js array object and the length of the array object is shown in cart. I want to load a view and display the cart items there in the view therefore I want to send the js array object as a parameter to laravel controller function through <a> tag when the user clicks on it.

Here is the <a> tag which should send the cart object to laravel controller:

<a href="#" >
    <i class="fa fa-shopping-cart"></i>
    <span id="cartLength"></span>
</a>

Here is the js function that increments cart array object:

function addToCart(id)
{
  if(! cart.includes(id) ) cart.push(id);

  cartLength.html(cart.length);
  $('#successCart'+id).html('Book added to cart.');

}

Here is the <a> tag that adds the item to cart by calling addToCart js function:

<a href="#" class="add-to-cart" 
   onclick="event.preventDefault(); addToCart('{{$book->id}}');">
   Add To Cart
</a>

Here is the controller function that returns view:

public function showCart(Request $request)
{
    return view('cart', ['cart' => $request->cart ]);
}

I don't know how to send the cart js object to laravel controller function through <a> tag and then load the view from there. Any help is appreciated in advance.

If you use an ajax request, on the success of the ajax, collect the (cart items)data and store it in a localstorage. Then display the items onload of the view you want using js. For example:

//let cart be the array you collected 

let cart = [];
let formdata = new FormData(cart);

$.ajax({
    url:"your/intended/url",
    type:"GET",
    data: formdata

}).done(function (data){
    cartItems = data;

    localStorage.setItem('cartItems', data);
    location.href = "view/cartPage";
})
