javascript - 将 object.keys 从对象数组映射到字符串

Question

我有一个数组，例如:

interface: [
    { _id: '1', name: 'Foo' },
    { _id: '2', name: 'bar },
    { _id: '3', name: 'boo}
]

我现在想将其映射到单个字符串 ->

this.dataSource.data = data.data.map(item => ({
     interface: item.interfaces.name,
}));

使得dataSource.data.interface内的结果看起来像'Foo, bar, boo'

Answer 1

您可以映射 name 属性并加入数组。

var data = { interface: [{ _id: '1', name: 'Foo' }, { _id: '2', name: 'bar' }, { _id: '3', name: 'boo' }]};

data.interface = data.interface.map(({ name }) => name).join(', ');

console.log(data);
