instMouseOverFilter Library Method
Short Description: Install MouseOver Filter
Signature: x.instMouseOverFilter (element,elimDoubleOver,elimSpontanousOut)
Class: Controller Class
Installs the MouseOverFilter for the given element.
If you attach animations to onmouseover and onmouseout you
might notice sometimes in certain browser constellations and controllers used
a strange behaviour, e.g. doublicate opening or closing animations.
All you need to do is to install the MouseOverFilter
on all elements having onmouseover and onmouseout
event handlers. It is most convenient to use instMouseOverFilterClass
for that purpose.
Technical details why the filter is needed are described below, but are not really
required to use it.
You can install the filter multiple times. You however need to install it
whenever the onmouseover or onmouseout handlers are modified.
Mouse Over Text
Move the mouse over here
<div id="ex" style="text-align:center" onmouseover="taccgl.actor('ex1',null,'visible').from(200,1000,10000).dur(0.3).start();taccgl.start()" onmouseout ="taccgl.actor('ex1',null,'hidden').to(0,0,2000).dur(0.3).start();taccgl.start()"> Move the mouse over here </div> <script> taccgl.begin(); taccgl.controller.instMouseOverFilter("ex"); </script> | |
Especlly when taccgl™ and its 3D Canvas is used, especially
togehter with the forwarding controller
the mouseover and mouseout events tend to
not work totally as desired. It might happen that extra mouseover or mouseout
events are generated at the start or end of an animation stating that the mouse
moved over or out the 3D canvas element. Also events might get lost in rare cases.
The MouseOverFilter eliminates mouseover and mouseout events related to the
3D canvas. If elimDoubleOver is set to true, doublicate
mouseover events are eleiminated.
If elimSpontanousOut
is set to true, doublicate mouseout events that had no
preceeding mouseover are eliminated.
