如何在 JavaScript 中轉換字串型別值到陣列型別值?
要轉換字串型別值到陣列型別值,請使用 parse() 方法。以下是程式碼 −
示例
var customerDetails='[ {"name": "John", "countryName": "US"}, {"name": "David", "countryName": "AUS"}, {"name": "Bob", "countryName": "UK"} ]'; console.log("The actual value="+customerDetails); var convertStringToArray=JSON.parse(customerDetails); console.log("After converting string to array objects="); console.log(convertStringToArray);
要執行以上程式,您需要使用以下命令 −
node fileName.js.
輸出
在此,我的檔名是 demo123.js。這將生成以下輸出 −
PS C:\Users\Amit\JavaScript-code> node demo123.js The actual value=[{"name": "John", "countryName": "US"}, {"name": "David", "countryName": "AUS"}, {"name": "Bob", "countryName": "UK"}] After converting string to array objects=[ { name: 'John', countryName: 'US' }, { name: 'David', countryName: 'AUS' }, { name: 'Bob', countryName: 'UK' } ]
