    Hi Jeremy,

    I’m using a slider scale and was wondering if there is any way of displaying the value to which the slider is currently set.

    Thank you!

    Hi Nadine,

    Here’s how to do it:

    newTrial(
    newText("scaleValue", "NA").before( newText("Score: ") )
    ,
    newScale("myScale", 7)
        .slider()
        .callback( getText("scaleValue").text(getScale("myScale")) )
        .print()
    ,
    getText("scaleValue").print()
    ,
    newButton("Next").print().wait()
)

    Note that values start with 0, so if you want to display a score starting with 1, you’ll need to use a Var element:

    newTrial(
    newVar("scaleVar", 0)
    ,
    newText("scaleValue", "NA").before( newText("Score: ") )
    ,
    newScale("myScale", 7)
        .slider()
        .callback( 
            getVar("scaleVar").set(getScale("myScale")).set(v=>parseInt(v)+1)
            ,
            getText("scaleValue").text( getVar("scaleVar") )
        )
        .print()
    ,
    getText("scaleValue").print()
    ,
    newButton("Next").print().wait()
)
