Extract Value From Object Using Javascript

I have the following object... var object = doc.$set; console.log(object); The console.log above outputs the following... { createdBy: 'o5Wye6LLMGNXLn7HY', createdAt: Mon Apr

Solution 1:

Try var orderedBy = doc.$set['contactDetails.orderedBy'];.

Since an object key is a numeric literal or a valid identifier name, it is necessary to quote the key contactDetails.orderedBy to avoid a syntax error.

Quotes can only be omitted if the property name is a numeric literal or a valid identifier name.

In the case of createdBy key, you could retrieve the value like object.createdBy but in the case of contactDetails.orderedBy you need to quote, so access it via object[contactDetails.orderedBy].

Solution 2:

If you want to manipulate object than you need understand the concept of key and value

see this examples

varobject={
 "iAmFirstKey":'I am value',
 "i.am.second.key":'i am value'
} 

so In your case your contacDetails.orderedBy is not Object inside Object it is an key ("string")

so use like this doc.$set['contacDetails.orderedBy']; you will get your value
