eval in Html5/Flash

ovo · **Posted:** February 28th, 2014, 10:21 am

I'd like to recognize objects based on their names. E.g. hot spot is named A_HS2, so I'd like to show an image named A_img but how to get object of this name?
eval works perfectly in Opus but doesn't work in HTML5/Flash.

Code:

var limitYposition = 700;
function displayObj(obj)
{
   var objName = obj.GetName();
   Debug.trace("object name: " + obj.GetName()  + "\n");//Mouse over object named: A_HS2 

   var objLetterArr = objName.split("_");// A, HS2
   var objLetter = objLetterArr[0];// A
   var posY = eval(objLetter + ".GetPosition().y");// 750
   //window.debug.log(eval(objLetter));//nothing happens in html
   var objImg = eval(objLetter + "_img");//my object (image) named: A_img
   // how to get object Id/Name for using in HTML5/Flash?
   
   //no to so important....
   if(posY > limitYposition )
   {
      if (objImg.IsShowing() == true)
      {
         objImg.Hide();
      }
      else
      {
         objImg.Show();
      }
   }
}

1. eval is a method of window - so use window.eval

2. The A_img object is a child of the page and therefore you'll need to reference the page object first

NB: eval is generally not good practice

Using a .window it means do it all in javascript. I was hoping Opus could translate it to javascript/flash for me.
With javascript is much more complicated because object names are not equal to their IDs in HTML.

Is there a DW javascript function which can get an object ID in HTML if I pass string from GetName() or GetUniqueObjectID? I did a small research in exported .js but with no success.

[update]
I tried to make it simple but it does nothing in HTML (no error code). Tested also on button - On Click and on hot spot. Opus is OK.

displayObj(D_IMG, D_drag)// passing objects to script which is on page

Code:

var limitYposition = 700;
function displayObj(imgObj, dragObj)
{
   //Debug.trace(imgObj);   
   //Debug.trace(dragObj);
   //window.console.log(imgObj);   
   //window.console.log(dragObj);
   
   var posY = dragObj.GetYPosition();// 750
   //window.console.log(posY);
   
   if(posY > limitYposition)
   {
      if (imgObj.IsShowing() == true)
      {
         imgObj.Hide();
      }
      else
      {
         imgObj.Show();
      }
   }
}

Problem is in not passing objects to the Script. If I place the script into the event it works.

Code:

var limitYposition = 700;
var posY = D_drag.GetYPosition();// 750

if(posY > limitYposition)
   {
      if (D_IMG.IsShowing() == true)
      {
         D_IMG.Hide();
      }
      else
      {
         D_IMG.Show();
      }
   }
}

Code:

var limitYposition = 700;

Remove the 'var'

Mack you are the real expert. It works like a charm without var (public, private, static is closer to me :-)

).

Finanly I've made a small change for detecting drag object position (console.log rulezz).

Code:

dragObj.m_droppedOn == null

Opus + HTML5 works. Not Flash but not a big deal for me.

The more i work with Opus the more I have to admire DW what they have created despite the fact that everything doesn't work as I would expect. I hope they will fix HTML5 issues soon.

Help is sometimes a bit brief but I'm happy for this forum and DW email support - otherwise I'd had given it up with Opus.

Thanks.

I noticed above that you have constructed your opusscript using user-defined (ie, developer-define) functions.

If I recall from the Opus Help files (probably OpusScript Help file), that 'user-defined' functions are not supported in Flex. Please check it for yourself to verify. Also, they also mention that scripts run in Flex return results immediately (I forget how they worded that limitation).

Flash doesn't see .m_droppedOn property. If I replace it for Y condition it works in Flash as well.

Thanks for your comment.
