Using Vue to iterate through elements

Using Vue to iterate through elements

I am struggling to loop through an array in a Vue component without duplicating the element specified in the 'v-for' directive. I have consulted the official Vue.js API documentation, as well as various online articles, but haven't found a suitable alternative for achieving this.

Here is my current code:

<div v-for="(item, index) in items">
  <foo :index="index">
  <foo/>
</div>

Desired output:

<foo :index="0"><foo/> 

<foo :index="1"><foo/>

<foo :index="2"><foo/>
//etc...

I have attempted the following code, but it does not work as expected:

<foo v-for="(item, index) in items":index="index">
<foo/>

Any assistance would be greatly appreciated! I only just started working with Vue.js yesterday.

It seems like you might have missed defining props in the foo component.

  <div id="app">
    <foo v-for="(item, index) in items" :index="index"></foo>
  </div>

  <template id="foo-temp">
    <div>
      <span>{{ index }}</span>
    </div>
  </template>

JS:

Vue.component('foo', {
  props: ['index'],
  template: '#foo-temp'
})

new Vue({

  el: '#app',

  data: {
    items: [
      {id: 1, title: 'One'},
      {id: 2, title: 'Two'},
      {id: 3, title: 'Three'}
    ]
  }

})
