vue 数组排序

声明数组：testlist:["002","001","003"]

想实现效果进行排序：testlist:["001","002","003"]

<script>
export default
{
methods:{
  dy()
  { this. sortByKey(this.testlist);  
   conslole.log(this.testlist); 
 }
 }
}
</script>

 

调用代码为

<script>
export default
{
methods:{
   sortByKey(array){
      return array.sort(function(a,b){
            return(a<b)?-1:(a<b?1:0)
      })
   } 
 }
}
</script>
