How to limit iteration of elements in `v-for`

Question

I'm building a small application in Vuejs 2.0 I'm having approx 15 iterating elements I want to limit the v-for for only 5 elements and can have more buttons to display the whole list. Is there any possibilities?

Answer 1

You can try this code

<div v-if="showLess">
    <div v-for="value in array.slice(0, 5)"></div>
</div> 
<div v-else> 
    <div v-for="value in array"></div>
</div> 
<button @click="showLess = false"></button>

You will only have 5 elements in the new array.

Update: Tiny change that makes this solution work with both arrays and objects

<div v-if="showLess">
  <div v-for="(value,index) in object">
    <template v-if="index <= 5"></template>
  </div>
</div> 
<div v-else> 
  <div v-for="value in object"></div>
</div> 
<button @click="showLess = false"></button>

Answer 2

Am I too late? You can solve this using computed properties:

<div v-for="value in computedObj">{{value}}</div>
<button @click="limit = null">Show more</button>

Then in data:

data(){
  return {
    object:[], // your original data
    limit: 5 // or any number you wish to limit to
  }
}

And finally in your computed properties:

computed:{
  computedObj(){
    return this.limit ? this.object.slice(0,this.limit) : this.object
  }
}

When your click the button, the limit is cleared and the whole data is shown/returned

Answer 3

you can try this solution to...

<div  class="body-table  div-table" v-for="(item,index) in items"  :key="item.id" v-if="items && items.length > 0 && index <= limitationList">....

and set your limit in data

data() {
  return {
    limitationList:5
  };
},

and set a function in you btn

  <button  @click="updateLimitation(limitationList)">
    show {{limitationList == 5 ? 'more' : 'less'}}
  </button>

and this your methods

updateLimitation(limitationList){
  if (this.limitationList == this.items.length) {
    this.limitationList = 5
  }else{
    this.limitationList = this.items.length
  }
}

i hope useful for you...
