Updating checkbox scale conditionally

[laiamt]

Hi Jeremy,

I would like to have a trial in which participants select an option in a radio button scale and, depending on what they chose, a different scale appears. So far, this works:

newTrial("location",
    newText("Where do you live?").print() .cssContainer({"margin":"1em"}),
    
    newScale("country", "US", "UK").radio() .labelsPosition("right") .log() .print().wait() .cssContainer({"margin":"1em"})
        .test.selected("US").success(
                     newScale("us", 'California', 'New York').radio() .labelsPosition("right")  .log() .print().wait() )
        .test.selected('UK').success(
                     newScale("uk", 'England', 'Scotland').radio() .labelsPosition("right")  .log() .print().wait() ),
          

    newButton("go") .print().wait()
)

However, I would like participants to be able to change their choice in the first scale (if they made a mistake, for example) and that the second scale gets updated accordingly. Is there a way to achieve this?

Thanks,

Laia

Hi Laia,

Place the code you have after the first wait in callback instead:

newTrial("location",
    newText("Where do you live?").print().cssContainer({"margin":"1em"})
    ,
    defaultScale.radio().labelsPosition("right").log()
    ,
    newButton("go")
    ,
    newScale("us", 'California', 'New York'),
    newScale("uk", 'England', 'Scotland')
    ,
    newScale("country", "US", "UK").print().cssContainer({"margin":"1em"})
        .callback( 
            getButton("go").remove(),
            getScale("uk").remove().test.selected().success(self.unselect()),
            getScale("us").remove().test.selected().success(self.unselect())
            ,
            self.test.selected("US")
            .success( getScale("us").print().wait(),getButton("go").print() ) 
            .failure( getScale("uk").print().wait(),getButton("go").print() ) 
        )
    ,
    getButton("go").wait()
)
