Detecting wether timelines has been loaded

[Jeff Roehl]

In jQuery, I can detect whether jQuery has been loaded and what version is running with:

if (window.jQuery === undefined || window.jQuery.fn.jquery !== '1.8.1')

Is there something similar I can do with Simile Timelines?

 

Thanks

if (window.Timeline === undefined) {

console.log("Timeline not loaded")

}

else {

console.log("Timeline.version = " + Timeline.version)

You can check to see if the Timeline object is undefined, or if the 'version' property on it doesn't equal a specific version. Something like this should do the same thing as the jQuery example you provided:

if (window.Timeline === undefined || window.Timeline.version !== '2.3.1')

If you'd like to easily see all the other properties available on the Timeline object, just do console.debug(Timeline); in a browser console. Most modern browsers have good developer tools for doing stuff like this, or have plugins available for it. (I use Chrome and its developer tools.)

Best,

Careful, note that the timeline object gets defined when timeline
_begins_ to load; using this heuristic might lead you to invoke timeline
before it _finishes_ loading the various supporting scripts.
