Script for saving GIF with Animation Loop Endless

Question

Hi,
I am searching for a way to use  "save for web" in a Photoshop CC Script.
I already found how to use the "save for web" using Script, but now i am stuck, because i cannot find any information on how to set
that the animation, i want to save as a Animated GIF File, can be set to loop endless.
I already tried to search in all the docs i found about scripting, but there is not a single information about saving gif with animation loop endless...
thanks,
Philipp

When you do use "save for web" and select GIF, on the bottom right, the loop mode can be selected. But i think i wouldn't matter to me if it's being set before saving the image.
I already tried to run the script, but somehow
"charIDToTID('Ordn')" for example won't run. Is this the same as charIDToTypeID? because i found charIDToTypeID is a function, but charIDToTID is not...
also the third line from the end, one of the functions seem not to work, i think....
But already you given me a real good answer to what i may try to search for, since i did not actually know that this is set within the timeline, i always used the option within the "save for web" dialog on the bottom-right.
I Solved my own problem ...
I just made Photoshop CC with a script log everything, then gotten to this:
function setLoopForever() {
var idsetd = charIDToTypeID( "setd" );
    var desc5 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref2 = new ActionReference();
        var idanimationClass = stringIDToTypeID( "animationClass" );
        var idOrdn = charIDToTypeID( "Ordn" );
        var idTrgt = charIDToTypeID( "Trgt" );
        ref2.putEnumerated( idanimationClass, idOrdn, idTrgt );
    desc5.putReference( idnull, ref2 );
    var idT = charIDToTypeID( "T   " );
        var desc6 = new ActionDescriptor();
        var idanimationLoopEnum = stringIDToTypeID( "animationLoopEnum" );
        var idanimationLoopType = stringIDToTypeID( "animationLoopType" );
        var idanimationLoopForever = stringIDToTypeID( "animationLoopForever" );
        desc6.putEnumerated( idanimationLoopEnum, idanimationLoopType, idanimationLoopForever );
    var idanimationClass = stringIDToTypeID( "animationClass" );
    desc5.putObject( idT, idanimationClass, desc6 );
executeAction( idsetd, desc5, DialogModes.NO );
Works perfect!
