I have an angular problem
I have my object
user = {name: 'Alexandre', email: '[email protected]'}
I need a way to show on the console
var attr = 'name';
var attr2 = 'email';
insira o código aqui
console.log(user.attr) e me retorne Alexandre;
console.log(user.attr2) e me retorne '[email protected];
The second parameter of the object would be dynamically variable, how can I execute it?
I've tried it like this and nothing is right
user.attr;
user.{attr};
user.(attr);
If I understand you correctly, you can access the properties of the object using the following notation:
var attr = 'name';
var attr2 = 'email';
console.log(user[attr]) // mesmo que "user.name"
// => 'Alexandre'
console.log(user[attr2]) // mesmo que "user.email"
// => '[email protected]'
More information here .
var user = '{"name": "Alexandre", "email": "[email protected]"}';
var usuario = JSON.parse(user);
for (var x in usuario) {
console.log(usuario[x]);
}
user = {name: 'Alexandre', email: '[email protected]'}
var attr = 'user.name';
var attr2 = 'user.email';
console.log(attr , attr2) retorna => "Alexandre" "[email protected]"
