从渲染阵列的每个上点击物品进入DOM和不断变化的价值

Question

所以，我得到这个代码从DOM里的数组是推动所有项目。

如何使每个项目的单击事件的工作？

编辑：

let items = {
  item1: {
    cost: 2200,
    owned: 0,
    type: "item type",
    name: "item1",
    desc: "item1 desc.",
    img: "img/item1.gif"
  },
  item2: {
    cost: 4400,
    owned: 0,
    type: "item type",
    name: "item2",
    desc: "item2 desc.",
    img: "img/item2.gif"
  },
};

for (let key of Object.keys(items)) {
  if (items[key].owned==0) {
    var el = document.createElement('div');
    var domString = '<div class="item"><div class="w3 h3 bg-center contain" style="background-image:url(' + items[key].img + ')"></div><span>'+ items[key].name +'</span><span>Price: '+ items[key].cost +'</span><span>'+ items[key].desc +'</span></div>';
    el.innerHTML =  domString;
    el.addEventListener('click', function() {
      items[key].owned = 1;
      console.log(items[key].name + ' ' + items[key].owned);
    });
    document.getElementById('shop').appendChild(el.firstChild);
  }
}

我希望的方式来改变点击一个项目变量。事件侦听器不会在此代码的工作。

使用对象键的分配的ID，然后添加事件监听器

for (let key of Object.keys(items)) {
  if (items[key].owned==0) {
    var el = document.createElement('div');
    var domString = '<div id="' + items[key] + '"><div class="w3 h3 bg-center contain" style="background-image:url(' + items[key].img + ')"></div><span>'+ items[key].name +'</span><span>Price: '+ items[key].cost +'</span><span>'+ items[key].desc +'</span></div>';
    el.innerHTML =  domString;
    document.getElementById('shop').appendChild(el.firstChild);
  }
}

for (let key of Object.keys(items)) {
  document.getElementById(items[key]).addEventListener('click', function() {
    items[key].owned = 1
  });
}

或者你可以简单地指定的div元素上监听使用document.createElement创建

for (let key of Object.keys(items)) {
  if (items[key].owned==0) {
    var el = document.createElement('div');
    var domString = '<div id="' + items[key] + '"><div class="w3 h3 bg-center contain" style="background-image:url(' + items[key].img + ')"></div><span>'+ items[key].name +'</span><span>Price: '+ items[key].cost +'</span><span>'+ items[key].desc +'</span></div>';
    el.innerHTML =  domString;
    el.addEventListener('click', function() {
       items[key].owned = 1
    });
    document.getElementById('shop').appendChild(el);
  }
}
