删除JSON元素-JavaScript？
假设以下是我们的JSON字符串-
var details =
[
{
customerName: "Chris",
customerAge: 32
},
{
customerName: "David",
customerAge: 26
},
{
customerName: "Bob",
customerAge: 29
},
{
customerName: "Carol",
customerAge: 25
}
]要删除JSON元素，请在JavaScript中使用delete关键字。
示例
以下是删除JSON元素的完整代码-
var details =
[
{
customerName: "Chris",
customerAge: 32
},
{
customerName: "David",
customerAge: 26
},
{
customerName: "Bob",
customerAge: 29
},
{
customerName: "Carol",
customerAge: 25
}
]
delete details[0].customerAge;
console.log(details);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demo211.js-
PS C:\Users\Amit\JavaScript-code> node demo211.js
[
{ customerName: 'Chris' },
{ customerName: 'David', customerAge: 26 },
{ customerName: 'Bob', customerAge: 29 },
{ customerName: 'Carol', customerAge: 25 }
