JS根据属性值从对象数组中删除指定元素

removeByValue: function(arr, attr, value) {  //数组，属性，属性值
                var index=0;
                for(var i in arr){
                    if(arr[i][attr]==value){
                        index=i;
                        break;
                    }
                }
                arr.splice(index,1);
             }

// 原数组
var cars = [
  {type:"BMW", year:2017},
  {type:"Audi", year:2019},
  {type:"porsche", year:2018}
];
// 方法
function removeByValue(arr, attr, value)
 { 
  var index=0;
  for(var i in arr){
    if(arr[i][attr]==value){
      index=i;
      break;
    }
  }
  arr.splice(index,1);
}
removeByValue(cars,"type","BMW");
console.log(cars);
