以上是我的Json响应。我想删除fuel_type重复值。我怎样才能做到这一点。在此先感谢如何从我的json数组中删除最大值

什么是*重复*？ –

[从JSON数组中删除重复对象]的可能重复（https://stackoverflow.com/questions/23507853/remove-duplicate-objects-from-json-array） – Ferus7

您在GetAllCar {}中有7个json对象。其中5个柴油机作为燃料类型，另外2个以汽油作为燃料类型。如果5和1中有2个，你是否想要1出来，是否意味着删除重复？ –

Array.prototype.removeRepeatAttr = function() { 
    var tmp = {}, a = this.slice(); 
    for(var i = j = 0; i < a.length; i++) { 
     if(!tmp[a[i].id]) { 
      tmp[a[i].id] = !0; 
      j++; 
     } 
     else { 
      this.splice(j, 1); 
     } 
    }; 
}
