I am grappling with a JSON object notation that looks like this:
[{"getCname('mail.fred.com.au')":[{"cname":"www.fred.com.au"}]}]
I am struggling to extract only the "cname" value in JavaScript, specifically I just want:
"www.fred.com.au"
My attempt at res[0].cname didn't yield the desired outcome.
In case you possess
const data = [{"getDomain('email.john.com')":[{"domain":"www.john.com"}]}];
You can then retrieve the URL value by using
const urlValue = data[0]["getDomain('email.john.com')"][0].domain;
The main object is in the form of an array, and the property's value with the peculiar lengthy name is also an array, which explains the presence of [0] in two spots.
If you're unsure about the 'getCname' key, you can try this workaround:
let data = [{"getCname('mail.fred.com.au')":[{"cname":"www.fred.com.au"}]}];
let firstKey = Object.keys(data[0])[0];
let cnameValue = data[0][firstKey][0].cname;
Check out the following code snippet:
var result = [{"getCname('mail.fred.com.au')":[{"cname":"www.fred.com.au"}]}];
result[0] ;// this will return Object {"getCname('mail.fred.com.au')":[{"cname":"www.fred.com.au"}]};
result[0]["getCname('mail.fred.com.au')"] ;// this will return Array [{"cname":"www.fred.com.au"}];
result[0]["getCname('mail.fred.com.au')"][0].cname ;// this will return "www.fred.com.au"
