如何在本地存储中使用不同的键存储不同的值？

Question

嗨，我想每次用户单击时都在现有数组中添加一个新值， 但是用我的代码，每次都删除数组。你能帮我吗？ 这是我的代码：

cameraSelected(){
    var getId = document.querySelector('.linkCart');
    var typeCamera = document.querySelector('.name');
    var priceCamera = document.querySelector('.price');
      var storeName = [];
      var storePrice = [];
      var cameras = {
        name : typeCamera.textContent,
        price : priceCamera.textContent
                }
      var nameItems = localStorage;
      var priceItems = localStorage;
    getId.addEventListener("click", (e)=>{
      e.preventDefault();
      storeName.push(cameras.name);
      storePrice.push(cameras.price);
    for (let names in storeName){
      nameItems.setItem("cameras", JSON.stringify(storeName));
    }
    for (let prices of storePrice){
      priceItems.setItem("prices", storePrice);
    }
  });
}
