determine object position or collision // rename Lectora object

[lrichmtg]

All,

I think I've seen this as an issue before, but can't find a solution. In a nutshell, I need to be able to either "rename" Lectora objects to a user-generated name rather than the "random" lectora-generated (HTML) name, or at least allow the compiled code to recognize a particular object as "this.".

I'm trying to either determine the X,Y position of an object or collision with another object. I need this to be flexible yet generic so the logic is easily reused without need for additional input. I also don't want to modify the lectora .js files or add new external .js files since i can't ensure they will be properly inserted.

I've been able to write, call, and test functions in both the core lectora file, as well as the external .js files (trivantis-image, trivantis-inline). My tests work if I "hard-code" Image####.objLyr.[...]. Unfortunately I can't seem to recognize this.objLyr.[...] when i call a function from the image object.

(i.e. --(image7774.objLyr.hasMoved = true) tests TRUE, but (this.objLyr.hasMoved = true) tests FALSE)

I'm using an action under my image object to Go To > Web Address > javascript: FunctionName(); to call functions.

Any ideas how I can capture "this... object" so I can rename the entry? That would open up a world of opportunities, efficiencies, and portability as a template.

Thanks in advance for your help!

There is no way I know of to do that with the current version of Lectora. I have put in a request for an action that would retrieve the HTML name of a specified Lectora object using the Lectora object name as a reference. No telling if or when that will happen.

I was afraid someone would say that, Ben. I got very close, but just could never program so that Lectora could determine which object was "this" object. I could add JS and find all the objects, but unfortunately coding to a particular object isn't a whole lot better and would require some lock-downs which are just a headache.

I also posted the same suggestion. I honestly don't see why your suggestion of an special action would be so difficult to implement. It looks like it would just be adding a few lines of javascript and a little code in the file to implement. Granted it would be of no use to non-programmers, it would make a world of difference to those who at least dabble in code...and as long as the programming is done and is transparent in a template, then even non-programmers can take advantage of it.

Thanks for your response. I was hoping you might have a magic cure.

Cheers!

Lisa, Send that in to Support@trivantis.com so they know I am not the only one requesting same.

if you add a eventhandler to the object you can get the id of the element from the event itself.
/*ADD EVENT HANDLER TO AN OBJECT ON THE PAGE BY PASSING THE NAME OF THE OBJECT, THE EVENT TO WATCH, AND THE FUNCTION TO CALL*/
function qAddEventHandler(qObject, sEventName, qEvent){
if (qObject.attachEvent)
{qObject.attachEvent('on' + sEventName,qEvent); }
else
if (qObject.addEventListener)
{qObject.addEventListener(sEventName,qEvent, false); }
}

function function(e){
var evt=window.event || e//evt evaluates to window.event or object, depending on which one is defined
if (!evt.target){evt.target=evt.srcElement;};//REQUIRED CONVERSION IN CASE OF BROWSER TYPE
var elemName = evt.target.name; //THIS IS THE NAME OF THE ELEMENT THAT THE ACTION OCCURRED ON (I.E. 'IMAGE2004OMG')
var eventType = evt.type;//THIS GIVE US THE TYPE OF EVENT THAT OCCURRED

there you go - need more info post again public or send me an email (peters@quizzicle.com)

I wasn't even thinking about looking at an event to get the object -- I suppose I was to focused on the object itself that i couldn't see the forest through the trees.

Thanks so much for your suggestion! I have some new curly bracket toys to play with
