Tips for showcasing a designated set of numbers in Vue Js while iterating?

Is there a way to specifically target numbers during a loop? For example, I only want to retrieve numbers 5 and above or within a certain range that I specify.

<select name="" id="input" class="form-control" v-model="selectcompetitionyear">
    <option v-for="n in 8" :value="n">Previous {{n}} games</option>
</select>

This would result in:

<select name="" id="input" class="form-control" v-model="selectcompetitionyear">
    <option value="5">Previous 5 games</option>
<option value="6">Previous 6 games</option>
<option value="7">Previous 7 games</option>
<option value="8">Previous 8 games</option>
</select>

Answer №1

Choosing the right method depends on the specific use case, but one approach would be:

var app = new Vue({
el: '#app',
    data: {
        selectcompetitionyear:5
    },
    methods:{
        getNumbers:function(start,stop){
            return new Array(stop-start).fill(start).map((n,i)=>n+i);
        }
    }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.3.3/vue.min.js"></script>
<div id="app" class="l-container l-vPad--mid">
    <select name="" id="input" class="form-control" v-model="selectcompetitionyear">
    <option v-for="n in getNumbers(5,9)" :value="n">Previous {{n}} games</option>
</select>
</div>
