如何在循环时获取特定数字,在我的情况下,我只想获得5个及以上数字或在我想要的范围内.

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

结果将是

<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>

解决方法:

这取决于用例,但其中一种方法是：

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

<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>
