Function Notes

Introduction

Tasker supports running JavaScript code in tasks or WebView scene elements. Most Tasker actions can be accessed direct from the JavaScript. JSON and XMLHTTPRequest are also directly available from the JavaScript code.

JavaScript in Tasks

JavaScript can be embedded inline in tasks via the JavaScriptlet (direct specification of JavaScript to run) or JavaScript (load script from file) actions.

In both cases, the JavaScript executes in sequence with the other actions in the task and variables are transparently converted so pieces of JavaScript can be interwoven throughout the task.

Embedded in HTML

WebView elements allow specification of mixed HTML and JS for the element content.

<H1 onClick="setWifi( false )">ClickMeToTurnOffWifi</H1>

This allows a single WebView to present a complete user-interface.

Local Variables

In JavaScript(let) actions, local variables (all lower case, e.g. %myvar) are directly accessible in the JavaScript without the % sign (e.g. myvar). If the script changes the value, the new value is transparently used by subsequent actions in the task.

In JavaScript embedded in HTML, the functions local and setLocal must be used to access variables local to the scene hosting the WebView.

Global Variables

Tasker global variables need to be accessed via global() and set via setGlobal().

Arrays

Local Tasker arrays are transparently available in Javascript(let)s and vice-versa. They are not available in WebViews.

Note that:

JavaScript array indices start at 0, whereas Tasker array indices start at 1
JavaScript uses [] while Tasker uses ()

So, for example, %arr(1) (Tasker) is equivalent to arr[0] (JavaScript).

Settings

Unlike normal Tasker actions, settings which are changed in JavaScript as part of a profile's enter task are not restored when the profile exits.

Execution

Execution Instances

Only one script can execute at one time. Once a piece of JavaScript is executing, it cannot be interrupted by another piece.

Working Off-Device

You might wish to develop long and/or complicated tasks off-device e.g. on a PC. There are two strategies for that:

1. `JavaScript` action

For off-device testing, use Menu / More / Developer / Save JS Library Template to get dummy definitions for the built in functions. Include that file when developing on your PC.

To test in your JavaScript code whether you're on-device or not, use

var onAndroid = ( global( 'sdk' ) > 0 );

By using the JavaScript action rather than JavaScriptlet you can easily access a file synced from PC to a file on the Android device.

2. Using WebView

If you specify a website URL as the content for your WebView, then testing the code on the target device is a simple matter of pushing the new version to your webserver and reloading the WebView on the device (see action Element Web Control)

Builtin Function Execution

Calls to most Tasker builtin functions (see below) are executed as normal single-action tasks and thus may be blocked by other executing tasks.

They execute at the priority of the task that executed the JavaScript plus two.

JavaScript(let): Alert,Confirm,Prompt

Scripts using these functions require a 'user-interface' and may cause interference with the currently running app (though in most cases they will not).

JavaScript(let): Auto Exit

By default, the JavaScript(let) action will end when the main execution sequence is finished.

If you are using asynchronous code e.g. via setTimeout() or other callbacks, you should deselect Auto Exit. You are then responsible yourself for telling Tasker to continue the task by calling exit().

In any case, execution will stop when the timeout configured for the action is reached.

JavaScript(let): Libraries

You can specify as many libraries as you want in the Libraries parameter, separated by newlines.

Several popular libraries are pre-selectable.

You may wish to download them manually to your local storage and change the http URL to a file URL so that Internet is not required to run your script.

Important: if you are using your own libraries developed on Windows, you may need to convert CRLF style line endings to Unix style LF.

Builtin Functions

Tasker makes most of it's actions available via functions which can be called directly via name in JavaScript(let) actions and WebView elements.

Exception: in WebView content where mode is set to URL, the functions must be prefixed by tk e.g. tk.flash('Woo!')

alarmVol / btVoiceVol / callVol / dtmfVol / mediaVol / notificationVol / systemVol / ringerVol

var ok = alarmVol( int level, bool display, bool sound )
