更改 JavaScript 中的嵌套对象键值
为此,请使用点 (.) 符号以及方括号 ([])。
示例
var details = { "customer": { "customerDetails": { "otherDetails": [ { "customerDetails": { "isMarried": false }, }, { "customerDetails": { "isMarried": false }, }, { "customerDetails": { "isMarried": false } } ] } } } console.log("All values are set to true="); for (var index = 0; index < details.customer.customerDetails['otherDetails'].length; index++) { details.customer.customerDetails['otherDetails'][index].customerDetails['isMarr ied'] = true; } for (var index = 0; index < details.customer.customerDetails['otherDetails'].length; index++) { console.log("isMarried:"+details.customer.customerDetails['otherDetails'][index ].customerDetails['isMarried']); }
要运行上述程序,你需要使用以下命令:
node fileName.js.
在此处,我的文件名是 demo186.js。
输出
这将产生以下输出:
PS C:\Users\Amit\javascript-code> node demo186.js All values are set to true= isMarried:true isMarried:true isMarried:true
