I have an array of objects. I want to get the key and value and print the data. eg. I have id, username and password and I want the username and password.
[
{"id":1,"name":"admin","password":"admin","role":"Admin"},
{"id":2,"name":"user","password":"user","role":"User"},
{"id":3,"name":"superadmin","password":"superadmin","role":"superadmin"}
]
The output should be
name : admin
password : admin,
name : user
password : user,
name : superadmin
password : superadmin
To iterate key values dynamically, you have to iterate object.
let arr = [
{"id":1,"name":"admin","password":"admin","role":"Admin"},
{"id":2,"name":"user","password":"user","role":"User"},
{"id":3,"name":"superadmin","password":"superadmin","role":"superadmin"}
];
arr.forEach((item, i) => {
for(let key in item) {
console.log(`${key}: ${item[key]}`);
}
});
If you would like to display only name and password, then you can add a condition.
arr.forEach((item, i) => {
for(let key in item) {
if (key === 'name' || key === "password") {
console.log(`${key}: ${item[key]}`);
}
}
});
Given the array you have, you simply need to loop through it:
var arr = [
{"id":1,"name":"admin","password":"admin","role":"Admin"},
{"id":2,"name":"user","password":"user","role":"User"},
{"id":3,"name":"superadmin","password":"superadmin","role":"superadmin"}
]
arr.forEach(function(obj) {
console.log('name: ' + obj.name);
console.log('password: ' + obj.password);
})
let data = [
{"id":1,"name":"admin","password":"admin","role":"Admin"},
{"id":2,"name":"user","password":"user","role":"User"},
{"id":3,"name":"superadmin","password":"superadmin","role":"superadmin"}
];
var out_data = data.reduce((a, b) => a + 'name: ' + b.name + ', password: ' + b.password + ' ', '');
console.log(out_data);
var arr = [
{"id":1,"name":"admin","password":"admin","role":"Admin"},
{"id":2,"name":"user","password":"user","role":"User"},
{"id":3,"name":"superadmin","password":"superadmin","role":"superadmin"}
]

Loop through the array
arr.forEach(function(data) {
console.log('name', data.name);
console.log('password', data.password);
})
