Displays an error message for each of the obligatory fields from the HTML document that have not been filled yet. See the IBEX documentation about the Form controller for a discussion of how fields are set as obligatory.
@newHtml("demographics", "example_intro.html") @ .print() @, @newButton("continue", "Continue to the next page") @ .print() @ .wait( @ getHtml("demographics").test.complete() $ .failure( getHtml("demographics").warn() ) @ )
Prints the content of exampleintro.html_ onto the page and adds a Continue button below it. The button is validated only when all the obligatory fields from exampleintro.html_ have been filled.
If the button is clicked and at least one obligatory field has not been filled, the
warncommand is executed and will display an appropriate error message.
