比方说,我们有一个对象,键作为字符串文字,它们的值作为对象,就像这样 -
const companies = { 'landwaves ltd': {employees: 1200, worth: '1.2m', CEO: 'Rajiv Bansal'}, 'colin & co': {employees: 200, worth: '0.2m', CEO: 'Sukesh Maheshwari'}, 'motilal biscuits': {employees: 975, worth: '1m', CEO: 'Rahul Gupta'}, 'numbtree': {employees: 1500, worth: '1.5m', CEO: 'Jay Kumar'}, 'solace pvt ltd': {employees: 1800, worth: '1.65m', CEO: 'Arvind Sangal'}, 'ambicure': {employees: 170, worth: '0.1m', CEO: 'Preetam Chawla'}, 'dis n dat': {employees: 540, worth: '1m', CEO: 'Mohit Sharma'}, }
我们需要编写一个函数,根据对象的键对对象进行排序并返回它。
const companies = { 'landwaves ltd': {employees: 1200, worth: '1.2m', CEO: 'Rajiv Bansal'}, 'colin & co': {employees: 200, worth: '0.2m', CEO: 'Sukesh Maheshwari'}, 'motilal biscuits': {employees: 975, worth: '1m', CEO: 'Rahul Gupta'}, 'numbtree': {employees: 1500, worth: '1.5m', CEO: 'Jay Kumar'}, 'solace pvt ltd': {employees: 1800, worth: '1.65m', CEO: 'Arvind Sangal'}, 'ambicure': {employees: 170, worth: '0.1m', CEO: 'Preetam Chawla'}, 'dis n dat': {employees: 540, worth: '1m', CEO: 'Mohit Sharma'}, }; const sortKeys = (obj) => { return Object.assign(...Object.entries(obj).sort().map(([key, value]) => { return { [key]: value } })); }; console.log(sortKeys(companies));输出结果
控制台中的输出将是 -
{ ambicure: { employees: 170, worth: '0.1m', CEO: 'Preetam Chawla' }, 'colin & co': { employees: 200, worth: '0.2m', CEO: 'Sukesh Maheshwari'}, 'dis n dat': { employees: 540, worth: '1m', CEO: 'Mohit Sharma' }, 'landwaves ltd': { employees: 1200, worth: '1.2m', CEO: 'Rajiv Bansal' }, 'motilal biscuits': { employees: 975, worth: '1m', CEO: 'Rahul Gupta' }, numbtree: { employees: 1500, worth: '1.5m', CEO: 'Jay Kumar' }, 'solace pvt ltd': { employees: 1800, worth: '1.65m', CEO: 'Arvind Sangal' } }
