I am trying to retrieve user fields using the LinkedIn API, in JavaScript.
I wish to pass this information as variables to another page using AJAX.
The code works fine, but a problem occurs when a user has an empty field.
For example, if I go to my LinkedIn Profile and delete my current job, the code stops working and no variables are passed because this field - positions.values[0].title is empty.
Removing this entire line document.getElementById("imgTitle").src = member.positions.values[0].title; will get it working again.
My question is how do I deal with the empty fields, and pass these variables as either "" or null using AJAX?
