以上是我的 Json 回复。我想删除fuel_type重复值。我怎样才能做到这一点。提前致谢

Answer 1

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);
        }
    };
}
