Example:
[js highlight=”1,7,11″ try=”true”]
newVar(“name”)
,
newTextInput(“nameInput”, “What is your name?”)
.settings.once()
.print()
.wait()
.setVar(“name”)
,
newText(“helloname”)
.settings.before( newText(“hello”, “Hello “) )
.settings.text( getVar(“name”) )
.print()
[/js]
Creates a Var element named name and adds a text box in which to enter a name. When the return/enter key is pressed while editing the input box, it disables the box and stores its value in the Var element named name. Then it prints a text reading Hello name, where name corresponds to the value of the Var element.
