更改 json 数组 localstorage 的值
我想将数组 2 的“Used”值从 0 更改为 1 我正在将所述数组保存在本地存储中
0: {Referencia: "AV02", Descripcion: "TEXT", Precio: "30", Usado: 0}
1: {Referencia: "AV02", Descripcion: "TEXT", Precio: "30", Usado: 0}
2: {Referencia: "AV04", Descripcion: "TEXT", Precio: "0.35", Usado: 0}
3: {Referencia: "AV01", Descripcion: "TEXT", Precio: "45", Usado: 0}
I would like to change the Used value of for example array 2 from 0 to 1
I am saving said array in localstorage
0: {Referencia: "AV02", Descripcion: "TEXT", Precio: "30", Usado: 0}
1: {Referencia: "AV02", Descripcion: "TEXT", Precio: "30", Usado: 0}
2: {Referencia: "AV04", Descripcion: "TEXT", Precio: "0.35", Usado: 0}
3: {Referencia: "AV01", Descripcion: "TEXT", Precio: "45", Usado: 0}

我猜您是在问当对象是数组的元素时如何更改对象属性的值。如果是这样：
在执行此操作之前，您必须从 localStorage 检索数据，并在完成后将其以相同键放回本地存储（根据需要使用 JSON 字符串化和解析步骤，本地存储仅存储字符串，对象和数组具有在存储之前转换为字符串）。
I'm guessing you are asking how to change the value of an object property when the object is an element of an array. If so:
You would have to retrieve the data from localStorage before doing this and put it back to local storage under the same key when you were done (with JSON stringifying and parsing steps as needed, local storage stores strings only, objects and arrays have to be converted to strings before storing).
