Referencing Widgets in Services

[tscur]

Hi all,

I've been developing in Thingworx for a while now and I was wondering if it was possible to reference a Widget Property in a service, something like:

if (condition) {

     [WidgetProperty] = [Something];

} else {

     [WidgetProperty] = [SomethingElse];

}

I know that Widgets have pre-defined services and inputs/outputs but my question is: Could I write a code that defines the input of the property based on a condition? If possible, how do I reference this property in the service?

Thank you.

You can not access widget reference in Thingworx JS service .This is doable in Studio (which is another AR product ) using angular snippet . But as per Thingworx it is not feasible .But you can use expression/Validator widget to evaluate a JS expression(condition) and use the output to bind to widget services .

Thank you for your answer @mnarang !

I've never used the Expression/Validador Widget, could you help me understand how it works?

Ok @mnarang , I saw the articles and videos and I am trying to see how it would work for me.

Let me explain the situation:

For example, I have a Data Table called People with two fields (Name [String], Numbers [InfoTable]). The Infotable Numbers has two fields (Number [Integer], Name [String]). My problem is that I have a Widget in which I am showing the data of a People's selected row's Numbers, keep this in mind. However, when the user clicks  "Add Person" in the People Data Table, i want to create a Data Table entry but also show the Numbers Infotable being created adding some rows to the Infotable. How can I use the same Widget to show both of the data. 

Basically, I want to activate an Adding Mode, not having to create another mashup and using the same widget.
