Js实现数据排序

function fn(data){
   return function(obj1,obj2){
     var val1=obj1[data]
     var val2=obj2[data]
        if(val1<val2){
          return 1
      }else if(val1>val2){
        return -1
      }else{
          return 0
      }
   }  
}  
this.allData=res.data.sort(fn("orderId")) //orderId后台接口参数
