从本地存储阵列删除1个项目

Question

我有如下的本地存储项目

(2) [{…}, {…}]
0
:
cityName
:
"durban"
__proto__
:
Object
1
:
cityName
:
"cape town"
__proto__
:
Object

我只想删除1个项目，基于cityName是否与本地存储项目匹配，即如果用户单击“ durban”，则删除durban。

我已经可以通过点击获取名称

  deleteCity(event){
    var target = event.currentTarget.id;
    console.log(target);
    var getLSCityName = localStorage.getItem('savedLocations');
    var getLSCityNameArr = JSON.parse(getLSCityName);

      for(var i = 0; i < getLSCityNameArr.length; i++){
        if (getLSCityNameArr[i].cityName == target){
          getLSCityNameArr.splice[i].cityName;
          localStorage.setItem('savedLocations', JSON.stringify(getLSCityNameArr));
        }
      } 
    }

Answer 1

please try like this

function deleteItem(index){
            var getLSCityName = localStorage.getItem('savedLocations');
            getLSCityName.splice(index,1); // delete item at index
        }
