Messages

The message tasks are built to be as simple as possible, all they do is present simple html templates. In order to load a template simply set it into the template property as a string, or set the appropriate URL into templateUrl. Thats it. (This is not relevant for most users, but the templates are rendered using angularjs $compile and therefore all the relevant directives are available).

The context for the template has the following variables available: {global, current, task}.

property description
template (text) A string of html to display (The template uses lodash templates).
templateUrl (text) A url to a html template (The template uses lodash templates).
keys Sets a key (or keys) that allow users to proceed. The keys property takes either a key (i.e. 'a') a keyCode (i.e. 65) or an array of such (i.e. ['a','b']).

 

The following example will display the message "Hello World. I am a template.", and procede when the keys space is pressed.

var task = {
    template: '<div>Hello World. I am a template.</div>',
    keys: ' '
}

The following task will do the exact same thing using two separate files:

manager.html

var task = {
    templateUrl: 'hello.htmlt',
    keys: ' '
}

hello.htmlt

<div>Hello World. I am a template.</div>

Proceeding

There are two types of controls that allow users to proceed to the next task.

First, you can use any element in your template as a proceed button, all you have to do is add the pi-message-done attribute to the appropriate element.

<button type="button" pi-message-done>Click here to proceed</button>

Alternatively you may use the keys property in order to set a key (or keys) that proceed. The keys property takes either a key (i.e. 'a') a keyCode (i.e. 65) or an array of such (i.e. ['a','b']).

This table shows several useful keyCodes for your convinience (there are more here):

Code Function
13 Enter
27 Escape
32 Space
37 Left arrow
38 Up arrow
39 Right arrow
40 Down arrow

Project Implicit build

The project implicit build has an optional "meta template" that you may use by setting the piTemplate property to true. When using it, you have several additional options.

property description
piTemplate (true, false or 'debrief') Activates the PI template. If set to 'debrief' activates the debrief template, and makes the debrief functions available.
header Header text.
footer Footer text.
buttonText Text for the proceed button (Defaults to: Click Here or press the space button to Proceed).
buttonHide Do not display the button at all (use this as a final page or for messages that use only the keys advance method).
demo If piTemplate is set to 'debrief', this property set to true will activate the demo version of the debrief.
noDonate (true or false) Do not show the donate button.

The project implicit template supports a debrief template activated by setting piTemplate to 'debrief'. If it is activated, there are two additional functions exposed from within the template. They can be used like so: <%= showPanel('body','header','footer') %> or <%= showFeedback({wrap:false}) %>.

showPanel(body, header, footer)

<%= showPanel('body','header','footer') %>

showPanel displays content within a stylized panel.

argument description
body The main text of the panel
header The panel header (optional)
footer The panel footer (optional)

showFeedback(options)

<%= showFeedback({wrap:false}) %>

showFeedback automatically gathers feedback from the global object and displays it within your page. It takes an options object as its single argument. The feedback is gathered from the global object by going through each task object (current) and searching for the feedback property. It depends on the individual tasks respecting this convention. You can fine tune the way feedback is collected and desplayed using the following options:

property description
pre A string to be injected before each feedback (default :'<p>').
post A string to be injected after each feedback (default :'</p>').
wrap Whether to wrap the results in a panel (default: true).
header If wrapped within a panel, set the panel heading.
noFeedback The text to show if no feedback is found (default: '<p>No feedback was found</p>').
property The default property in which to look for the feedback string (default: 'feedback').
exclude An array of task names to skip when gathering feedback.
