If I have a JSON object like this:
{
"message": {
"name": { "stringLengthTooShort": "blub" }
}
}
The name of the property (here) stringLengthTooShort
is changing every time,
how could I simply just get the child property of name
with JS?
At the moment I have message.name
but how could I get now the child of it?
if it's always the first property of message.name
, you could do something like:
var keys = [];
for (var l in message.name) {
if (message.name.hasOwnProperty(l)){
keys.push(l);
}
}
//=>first property value should now be in message.name[keys[0]]);
// (its label is keys[0])
Edit: nine years after this answer all modern browsers support es20xx, so it's safe to use:
const obj = {
"message": {
"name": { "stringLengthTooShort": "blub" }
}
};
console.log(Object.keys(obj.message.name)[0]);
