getVar(id).settings.global() (since beta 0.3)
Makes the Var element accessible from the script that has not been evaluated yet (=~ all the script below .settings.global()).
Note: any newVar command using the same id will be ignored if it comes further below the .global() setting command. This is particularly helpful when calling newVar in the Header, the Footer or within Template: the value of the global Var element will not be reset with each new trial
Example:
[js highlight=”3″]PennController(
newVar(“participantsName”, “”)
.settings.global()
,
newTextInput(“name”, “Please write your name”)
.print()
.wait()
.setVar( “participantsName” )
)
.log(“Participant”, getVar(“participantsName”) );
PennController(
newText(“hello”, “How are you today “)
.settings.after( newText(“name”, “”).settings.text(getVar(“participantsName”)) )
.print()
,
newButton(“good”, “Good, thank you”)
.settings.after( newButton(“bad”, “Not so well”) )
.print()
,
newSelector(“mood”)
.settings.add( getButton(“good”), getButton(“bad”) )
.wait()
)
.log(“Participant”, getVar(“participantsName”) );
[/js]
The code above creates two PennController trials: the first one creates a global Var element named participantsName whose value is set to the text contained in the TextInput element at the end of the trial; the second trial prints a Text element reading “How are you today “ and appends another Text element to its right, whose content is set to the value of the global Var element.
