如何只获取对象值的第一个单词-JavaScript？
假设以下是我们的对象-
const employeeDetails = [
{
employeeName: "John Smith",
employeeTechnology: "JavaScript HTML"
},
{
employeeName: "David Miller",
employeeTechnology: "Java Angular"
}
]您可以根据空间使用split()。
示例
以下是代码-
const employeeDetails = [
{
employeeName: "John Smith",
employeeTechnology: "JavaScript HTML"
},
{
employeeName: "David Miller",
employeeTechnology: "Java Angular"
}
]
const objectValues = employeeDetails.map(emp => {
var [technology1, technology2] = emp.employeeTechnology.split(/\s/);
return {
technology1, technology2,
employeeName: emp.employeeName
}
});
console.log(objectValues);要运行上述程序，请使用以下命令-
node fileName.js.
在这里，我的文件名为demo244.js。
输出结果
以下是控制台上的输出-
PS C:\Users\Amit\javascript-code> node demo244.js
[
{
technology1: 'JavaScript',
technology2: 'HTML',
employeeName: 'John Smith'
},
{
technology1: 'Java',
technology2: 'Angular',
employeeName: 'David Miller'
}
]
