更改JavaScript中嵌套对象键的值

为此，请使用点号（。）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']);
}

要运行以上程序，您需要使用以下命令-

node fileName.js.

在这里，我的文件名为demo186.js。

输出结果

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
