javascript - 从数组数组中删除

Question

我正在尝试使用 js 从数组中删除某些项目

这是我的数组

[
    {
        "Pizza": "Margarita",
        "Size": "Twelve Inch Stuffed Crust",
        "Base": "Deep Base",
        "Price": "6.50"
    },
    {
        "Pizza": "Hot Vegetarian",
        "Size": "Twelve Inch",
        "Base": "Deep Base",
        "Price": "6.00"
    },
    {
        "Pizza": "Vegetarian",
        "Size": "Ten Inch Stuffed Crust",
        "Base": "Deep Base",
        "Pricelabel": "Price",
        "Price": "6.50"
    },
    {
        "Pizza": "Hot Vegetarian",
        "Size": "Fourteen Inch Stuffed Crust",
        "Base": "Deep Base",
        "Pricelabel": "Price",
        "Price": "10.50"
    }
]

在我的屏幕上有 4 个删除按钮，名为“deletebutton_0、deletebutton_1、deletebutton_2、deletebutton_4

例如，如果我点击deletebutton_0，js将从数组中删除第一个项目的所有详细信息，

{"Pizza":"Margarita","Size":"Twelve Inch Stuffed Crust","Base":"Deep Base","Price":"6.50"}

我对 js 很菜，还在学习中。

尝试

array.splice(index,1) 其中 array 是您的数组，index 是您要删除的对象的索引
