Vue Js - Loop via v-for X times (in a range)

Question

How can I repeat a loop via v-for X (e.g. 10) times?

// want to repeat this (e.g.) 10 times

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

The documentation shows:

<ul>
  <li v-for="item in 10">{{ item }}</li>
</ul>

// or 

<li v-for="n in 10">{{ n }} </li>

// this doesn't work

<li v-for="item in 10">{{ item.price }}</li>

but from where does vue know the source of the objects? If I render it like the doc says, I get the number of items and items, but without content.

Answer 1

You can use an index in a range and then access the array via its index:

<ul>
  <li v-for="index in 10" :key="index">
    {{ shoppingItems[index].name }} - {{ shoppingItems[index].price }}
  </li>
</ul>

You can also check the Official Documentation for more information.
