需要在 javascript 中将特定字符串与数组分开

Question

我有这样的输出

输出：

[{service: 'xdc'},{service: 'cddc'}, {service:
'cdcd'},{service: 'cddc'}]

我需要这样转换

输出：[xdc,cddc,cdcd,cddc]

Answer 1

您可以使用Array.prototype.map() combined with Destructuring assignment

代码：

const output = [{service: 'xdc'},{service: 'cddc'}, {service: 'cdcd'},{service: 'cddc'}]

const result = output.map(({ service }) => service)

console.log(result)

Answer 2

在这种情况下，您可以使用简单的 forEach() 循环：

var data = [{service: 'xdc'},{service: 'cddc'}, {service:
'cdcd'},{service: 'cddc'}]

var output = [];

data.forEach(element => {
output.push(element.service);
});

console.log(output);

Answer 3

使用Array.map():

const output=[{service: 'xdc'},{service: 'cddc'}, {service: 'cdcd'},{service: 'cddc'}]
const result = output.map(el => el.service)
console.log(result)

Answer 4

var datas = [{服务：'xdc'}，{服务：'cddc'}，{服务：'cdcd'}，{服务：'cddc'}]

data.map(数据 => data.service);
