Re: Need help cleaning up a script and adding loop

Awesome.

Any idea how to add this to the following script listener bit that changes the canvas size?

/ =======================================================

var idCnvS = charIDToTypeID( "CnvS" );

    var desc105 = new ActionDescriptor();

    var idWdth = charIDToTypeID( "Wdth" );

    var idPxl = charIDToTypeID( "#Pxl" );

    desc105.putUnitDouble( idWdth, idPxl, WIDTH GOES HERE? );

    var idHght = charIDToTypeID( "Hght" );

    var idPxl = charIDToTypeID( "#Pxl" );

    desc105.putUnitDouble( idHght, idPxl,  HEIGHT GOES HERE?);

    var idHrzn = charIDToTypeID( "Hrzn" );

    var idHrzL = charIDToTypeID( "HrzL" );

    var idCntr = charIDToTypeID( "Cntr" );

    desc105.putEnumerated( idHrzn, idHrzL, idCntr );

    var idVrtc = charIDToTypeID( "Vrtc" );

    var idVrtL = charIDToTypeID( "VrtL" );

    var idCntr = charIDToTypeID( "Cntr" );

    desc105.putEnumerated( idVrtc, idVrtL, idCntr );

executeAction( idCnvS, desc105, DialogModes.NO );

My initial thought was that I'd add the math bits above this, and then call the variables in the part where I put WIDTH GOES HERE, but that's not clear to me, since there's some if/then going on, and I'm not sure how to account for that.  Perhaps the script listener isn't the way to go for this?
