如何修改Photoshop脚本：仅对选中图层清除选区

原脚本可清除所有图层的当前选区，现需修改为仅对选中图层执行清除选区操作，以下是修改完成的完整脚本：

#target photoshop

// 2023, use at your own risk;
if (app.documents.length > 0) {
    /* Start Process selected layers - from jazz-y */
    var s2t = stringIDToTypeID;
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('targetLayersIDs'));
    r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
    var lrs = executeActionGet(r).getList(p),
        sel = new ActionReference();

    for (var i = 0; i < lrs.count; i++) {
        // 选中当前遍历到的图层
        (r = new ActionReference()).putIdentifier(s2t('layer'), p = lrs.getReference(i).getIdentifier(s2t('layerID')));
        (d = new ActionDescriptor()).putReference(s2t("target"), r);
        executeAction(s2t('select'), d, DialogModes.NO);
        
        // 清除该图层的选区
        try {activeDocument.selection.clear()}
        catch (e) {}
    }
    /* End Process selected layers - from jazz-y */
};

////// based on code by mike hale, via paul riggott //////
function selectLayerByID(id,add){ 
add = undefined ? add = false:add 
var ref = new ActionReference();
    ref.putIdentifier(charIDToTypeID("Lyr "), id);
    var desc = new ActionDescriptor();
    desc.putReference(charIDToTypeID("null"), ref );
        if(add) desc.putEnumerated( stringIDToTypeID( "selectionModifier" ), stringIDToTypeID( "selectionModifierType" ), stringIDToTypeID( "addToSelection" ) ); 
        desc.putBoolean( charIDToTypeID( "MkVs" ), false ); 
    try{
    executeAction(charIDToTypeID("slct"), desc, DialogModes.NO );
}catch(e){
}
};

修改说明 #

• 移除了原脚本中遍历所有图层的collectLayersNamesIndexAndIdentifier函数及相关逻辑
• 替换为获取选中图层ID列表的代码，仅循环处理用户选中的图层
• 循环内先定位选中目标图层，再执行清除选区操作
• 保留原有的异常捕获逻辑，避免无选区的图层导致脚本中断
