数组推入js中的数组到php中的变量

Question

我想知道如何使用数组推送来为DeliveryArea添加值。所有的值都将来自php变量。我是使用js的初学者，想要学习和入侵JS。

var Category = {
    "Status": ["Unpaid", "Paid", "Pending"],
    "OrderDate": ["123", "123", "123"],
    "DeliveryArea": [],
}

Answer 1

使用对象名和键名，如下所示的Category.DeliveryArea

​

var Category = {

  "Status": ["Unpaid", "Paid", "Pending"],
  "OrderDate": ["123", "123", "123"],
  "DeliveryArea": [],
}

let arr = ['arr1', 'arr2', 'arr3'];

arr.forEach(function(item) {
  Category.DeliveryArea.push(item)

})

console.log(Category)

​

如果希望通过变量访问密钥，请使用方括号

​

var Category = {
  "Status": ["Unpaid", "Paid", "Pending"],
  "OrderDate": ["123", "123", "123"],
  "DeliveryArea": [],
}

let keyName = 'DeliveryArea'

let arr = ['arr1', 'arr2', 'arr3'];

arr.forEach(function(item) {
  Category[keyName].push(item)

})

console.log(Category)
