I am developing my own experience in Thingworx studio. I just want to use Java script to invoke my custom Thingworx service with a parameter input. Thanks very much.

    If you are looking to get the data from a ThingWorx service, then it can be done as:

    var result = $scope.app.mdl['Thingname'].svc['servicename'] ;

       // which invokes the service and returns the service output

    And to assign the parameter value -

    $scope.app.mdl['Thingname'].data.parameter['parametername'] = "input value" ;

    In order to invoke service with the required input parameter, you can try assigning the parameter first and in the next step invoke the service execute step.

      Hi, Giri. If i use script  to set parameter like:  $scope.app.mdl['ServiceItem-1'].data.parameter['currentStep'] = 'xxxxx',  debug console will report error "TypeError: Cannot read property 'parameter' of undefined".

      I am facing the same issue. What would be the reason that the thing is undefined in javascript? but when I bind a property from the very same thing directly to some widget I get the property values as expected.

      Hi,

      When I console.log the content of mdl object in the home.js as below:

      console.log($scope.app.mdl);

      I get the object nicely logged in the console

      If I then copy the path to the BatteryCharge property (just under the pop-up) and try to log its value as follows:

      console.log($scope.app.mdl.KCERoofBox.properties.BatteryCharge);

      I'll get the following error:

      console_4.PNG

      So it seems that the KCERoofBox object is undefined.

      What am I doing wrong?

      I've also tried the following call with the same results:

      console.log($scope.app.mdl['KCERoofBox'].properties['BatteryCharge']);


      Please could someone help me out with this one?
