Ways to extract and utilize data from a nested object within an Observable Array

  • I've been searching everywhere for a solution to this question but haven't had any luck.

Recently, I came across an observable array that only has one entry:

https://i.sstatic.net/Op0wB.png

This single entry is stored in self.user()

POSData.Users.getByEmail(sEmail)
        .then(data => {
        //console.log(data)
        self.user.push(data);
    })

Now, my goal is to extract specific values and assign them to their own observables, but I'm facing a roadblock.

I've attempted the following code snippet to access the firstName...

console.dir(self.user());

    //console.log(self.user()[0].data.firstName());
    //console.log(self.user().firstName());
    //console.log(self.user().data.firstName());
    //console.log(self.user()[0].data.firstName());
    //console.log(self.user().data[1].firstName());


If anyone knows how to navigate deeper into the data structure to find the information I need, please share your insights.

Thank you for taking the time to read through this

Best regards,

John

Storing the original data obtained from the service in an array is crucial. It's important to access the data members in their raw form, rather than treating them as observables.Avoid trying to call the firstName property as if it were an observable, since it is just a string within the data property. In your example, only self.user appears to be observable.

Based on the provided screenshot, the new data seems to have the following structure:

{
  data: {
    firstName: 'John',
    lastName: 'Smith'
  },
  message: 'User retrieved successfully',
  status: null
}

To retrieve the first name of this object within your user array, use the following syntax:

self.user()[0].data.firstName
