Iterating Over Items in Vue.js With V-for

V-for with Objects

data() {
  return {
    objectItems: {
      key1: 'item1',
      key2: 'item 2',
      key3: 'item3'
    }
  }
}
<ul>
  <li v-for="item in objectItems">{{ item }}</li>
</ul>

<ul>
  <li v-for="(item, key, index) in objectItems">
    {{ item }} - {{ key }} - {{ index }}
  </li>
</ul>

V-for with Range

<ul>
  <li v-for="item in 15">{{ item }}</li>
</ul>

//using Key
<ul>
  <li v-for="item in shoppingItems" :key="item.name">
    {{ item.name }} - {{ item.price }}
  </li>
</ul>

Filtering list

Using computed values to filter items

<ul>
  <li v-for="item in itemsLessThanTen" :key="item.name">
    {{ item.name }} - {{ item.price }}
  </li>
</ul>
data() {
  return {
    shoppingItems: [
      {name: 'apple', price: '7'},
      {name: 'orange', price: '12'}
    ]
  }
},
computed:{
  itemsLessThanTen: function() {
    return this.shoppingItems.filter(function(item) {
      return item.price > 10;
    })
  }
}

Using a method to filter items

<ul>
  <li v-for="item in filterItems(shoppingItems)" :key="item.name">
    {{ item.name }} - {{ item.price }}
  </li>
</ul>

data() {
  return {
    shoppingItems: [
      {name: 'apple', price: '7'},
      {name: 'orange', price: '12'}
    ]
  }
},
methods:{
  filterItems: function(products) {
    return products.filter(function(item) {
      return item.price > 10;
    })
  }
}
