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.
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>
Note that this is 1-indexed: in the first iteration, index is 1, and in the second iteration, index is 2, and so forth.
You can also check the Official Documentation for more information.
I have solved it with Dov Benjamin's help like that:
<ul>
<li v-for="(n,index) in 2">{{ n }}, {{ index }}</li>
</ul>
Note that in this case, n is 1-indexed, and index is 0-indexed.
And another method, for both V1.x and 2.x of vue.js
Vue 1:
<p v-for="item in items | limitBy 10">{{ item }}</p>
Vue2:
// Via slice method in computed prop
<p v-for="item in filteredItems">{{ item }}</p>
computed: {
filteredItems: function () {
return this.items.slice(0, 10)
}
}
I had to add parseInt() to tell v-for it was looking at a number.
<li v-for="n in parseInt(count)" :key="n">{{n}}</li>
