Question

让我们想象一下：

＆＃13;

var fruits = [{ "Banana" : "yellow", "lemon" : "yellow"}, {"Orange" : "orange", "Mango" : "orange"}, {"Apple" : "red", "strawberry" : "red"}];

fruits.push({"Kiwi" : "green", "Green Apple" : "green", "watermelon" : "green" });

console.log(fruits);

＆＃13;

现在我有一个数组＆＃34;水果＆＃34;，内有对象，我正在使用＆＃34; push（）＆＃34;添加新对象的方法。

如果我想添加一种新的黄色水果，例如＆＃34;牙买加香蕉：黄色＆＃34;在黄色物体里面，我怎么能这样做？

Answer 1

你要做的事情不会很好。尝试这样的事情：

group by

Answer 2

如果需要，您需要引用键和字符串值，但不要引用带有冒号的wole部分：Object initializer。

var fruits = [{ Banana: "yellow", lemon: "yellow" }, { Orange: "orange", Mango: "orange" }, { Apple: "red", strawberry: "red" }];

fruits.push({ Kiwi: "green", "Green Apple": "green", watermelon: "green"});

console.log(fruits);

Answer 3

使用动态属性访问（括号表示法），不要忘记属性名称和其他水果对象中:之间的引号：

var fruits = [{
  "Banana": "yellow",
  "Lemon": "yellow"
}, {
  "Orange": "orange",
  "Mango": "orange"
}, {
  "Apple": "red",
  "Strawberry": "red"
}]

fruits.push({
  "Kiwi": "green",
  "Green Apple": "green",
  "Watermelon": "green"
})

fruits[0]["Jamaican Banana"] = "yellow"

console.log(fruits)

但是，我建议（比如Ryan和Mehul Mohan已经使用）在顶级fruits对象中使用数组（换句话说，按颜色对数据进行排序）：

var fruits = {
  "yellow": ["Banana", "Lemon"],
  "orange": ["Orange", "Mango"],
  "red": ["Apple", "Strawberry"]
}

fruits["green"] = ["Kiwi", "Green Apple", "Watermelon"]

fruits["yellow"].push("Jamaican Banana")

console.log(fruits)

Answer 4

var fruits = [{'Banana' :'yellow', 'lemon' : 'yellow'}, {'Orange' : 'orange', 'Mango' : 'orange'}, {'Apple' : 'red', 'strawberry' : 'red'}];

fruits.push({'Kiwi' : 'green', 'Green Apple' : 'green','watermelon' : 'green'});
console.log(fruits);

如何在数组中添加值？
