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
