Trying to send this html into localstorage so I can use in a new cart page but it keep giving me an error

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

This is the HTML code:

<div class="cofefe">

                    <img src="photos/Shop%20-%20French%2Roast.png">

                    <p>Somecoffee</p>

                    <p>15</p>

                    <p>French Roast</p>

                    <button id="cartitem1" onclick="addCart()" class="button">Add to cart</button>

                </div>

This is the javascript:

function addCart() {

        var name = this.parentElement.children[1].getContext;

        var prices = this.parentElement.children[2].getContext;



        var storeThis = {'name': name, 'price': prices};

        localStorage.setItem(name, JSON.stringify(storeThis)); 

    }

In the chrome I get :

cart.js:2 Uncaught TypeError: Cannot read property 'children' of undefined
at addCart (cart.js:2)
at HTMLButtonElement.onclick (shop.html:40)

and

Uncaught TypeError: Cannot read property 'children' of undefined

I am sure there is something wrong with the javascript. I don't understand what.

Your JavaScript code has nothing for this to work on. You need to get the current target. Change your function to the below:

function addCart(event) {

    var name = event.target.parentElement.children[1].getContext;

    var prices = event.target.parentElement.children[2].getContext;

    var storeThis = {'name': name, 'price': prices};

    localStorage.setItem(name, JSON.stringify(storeThis)); 

}

EDIT:

Here's a failsafe way to make it work - use JavaScript to add an event listener rather than an inline HTML event listener:

<button id="cartitem1" class="button">Add to cart</button>

JavaScript:

document.getElementById("cartitem1").addEventListener("click", function(e) {

    addCart(e);

})
