Javascript-如何在HTML中显示SessionStorage obj

我在sessionStorage中有对象数据，我想通过循环在HMTL中将它们显示为列表。我如何做到这一点

SesionStorage.cart数据字符串化：

[{"itemName":"WS: FaceShield, 10pcs pack","itemPrice":0,"itemQuantity":"1"},{"itemName":"Faceshield, 1 pc","itemPrice":0,"itemQuantity":"1"}]

我现在要做的是，在再次将它们解析为JSON对象后，将它们显示在列表中。

假设您有

<ul id="myUL"></ul>

编写一个循环，创建

元素并将它们附加到DOM中。请阅读并创建一个您的最佳尝试。

// Let's define our array
const arr = [
  {"itemName":"WS: FaceShield, 10pcs pack","itemPrice":0,"itemQuantity":"1"}, 
  {"itemName":"Faceshield, 1 pc","itemPrice":0,"itemQuantity":"1"}
];

// Store it into LS...
localStorage.arr = JSON.stringify(arr);
// Read it from LS
const LS_arr = JSON.parse(localStorage.arr);


// Create a helper for new elements... 
const ELNew = (sel, attr) => Object.assign(document.createElement(sel), attr || {});


// Loop the array and create LI elements
const LIS = LS_arr.reduce((DF, item) => {
  DF.append(ELNew('li', {
    textContent: `Name: ${item.itemName} Price: ${item.itemPrice}`
  }));
  return DF;
}, new DocumentFragment());

// Once our DocumentFragment is populated - Append all at once!
document.querySelector("#myUL").append(LIS);
