JavaScript How to get all 'name' values in a JSON array?
Let’s say the following is our JSON array −
var details = [
{
"customerDetails": [
{
"customerName": "John Smith",
"customerCountryName": "US"
}
]
},
{
"customerDetails": [
{
"customerName": "David Miller",
"customerCountryName": "AUS"
}
]
},
{
"customerDetails": [
{
"customerName": "Bob Taylor",
"customerCountryName": "UK"
}
]
}
]To get only the CustomerName values, use the concept of map() −
Example
var details = [
{
"customerDetails": [
{
"customerName": "John Smith",
"customerCountryName": "US"
}
]
},
{
"customerDetails": [
{
"customerName": "David Miller",
"customerCountryName": "AUS"
}
]
},
{
"customerDetails": [
{
"customerName": "Bob Taylor",
"customerCountryName": "UK"
}
]
}
]
var allCustomerName = details.map(obj=>
obj.customerDetails[0].customerName);
console.log(allCustomerName);To run the above program, you need to use the following command −
node fileName.js.
Here my file name is demo206.js.
Output
PS C:\Users\Amit\javascript-code> node demo206.js [ 'John Smith', 'David Miller', 'Bob Taylor' ]
