Question

I have a JSON object

{
    "data": [{
        "user_id":"1",
        "user_name":"test",
        "user_phone":"2147483647",
        "user_email":"[e-mail]"
    }]
}

and a jQuery loop function

$.each(responseData, function(index, ProfileData) {
    profiles.push(
        application.getModel("Profile", [ ProfileData.user_id, ProfileData.user_name, ProfileData.user_phone, ProfileData.user_email ] )
    );
});

But when the JSON object becomes this

{
    "data": [{
        "firm_id":"1",
        "firm_name":"Firm",
        "firm_phone":"2147483647",
        "firm_email":"[e-mail]"
    }]
}

Then I want to check whether the JSON data has user or firm extensions, and also need to use this in the push() instead.

application.getModel( "Profile", [ ProfileData.user_id, ProfileData.user_name, ProfileData.user_phone, ProfileData.user_email ] )

You can check for the existence of a property inside an object like so:

if('user_id' in ProfileData)

So your solution might look like this:

$.each(responseData, function(index, ProfileData) {
    if('user_id' in ProfileData) {
        profiles.push(
            application.getModel("Profile", [ ProfileData.user_id, ProfileData.user_name, ProfileData.user_phone, ProfileData.user_email ] );
        );
     } else {
        profiles.push(
            application.getModel("Profile", [ ProfileData.firm_id, ProfileData.firm_name, ProfileData.firm_phone, ProfileData.firm_email ] );
        );
     }
});

Another approach would be to coalesce the different properties, and use whichever one is defined:

$.each(responseData, function(index, ProfileData) {
    profiles.push(
        application.getModel("Profile", [ 
            ProfileData.user_id    || ProfileData.firm_id, 
            ProfileData.user_name  || ProfileData.firm_name, 
            ProfileData.user_phone || ProfileData.firm_phone, 
            ProfileData.user_email || ProfileData.firm_email
        ] );
    );
});
