本文介绍了如何使用JavaScript的反射API获取对象如ArtLayer的属性和方法，通过`reflectProps`和`reflectMeths`函数实现，实例演示了获取`activeDocument.activeLayer`的详细信息。

如何获取对象的属性和方法，可以通过反射接口

比如：获取layer对象的属性和方法：

function reflectProps(obj) {
    var props = obj.reflect.properties;
  
for (var i = 0, len = props.length; i < len; i++) {
        try {
            $.writeln(props[i].name + ' = ' + obj[props[i].name]);
              WriteData(props[i].name + ' = ' + obj[props[i].name])
        } catch (e) {}
    }
}

function reflectMeths(obj) {
    var meths = obj.reflect.methods;
    for (var i = 0, len = meths.length; i < len; i++) {
        try {
            $.writeln(meths[i].name + '();');
            WriteData(meths[i].name + '();')
        } catch (e) {}
    }
}
function WriteData(Txt)
{  
	var file = new File(Folder.desktop + "/rflection.txt");  
	 file.open("a", "TEXT",null);  
      file.encoding = "UTF8";  
 	file.seek(0,2);  
 	$.os.search(/windows/i)  != -1 ? file.lineFeed = 'windows'  : file.lineFeed = 'macintosh';  
	file.writeln(Txt);  
	file.close();  
} 
// Example of use:
   //     var r = new ActionReference();  
   //      var d = new ActionDescriptor();  	 
	//	r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum")); 
     //     d.putReference(charIDToTypeID('null'), r);   
     //   var options = executeAction(charIDToTypeID( "getd" ), d, DialogModes.NO);
        //app.activeDocument.activeLayer
        
 var lay =app.activeDocument.activeLayer
 WriteData("\n***************"+"["+lay.constructor.name+" ]"+" properties **********************\n")
 reflectProps(lay);
 WriteData("\n***************"+"["+lay.constructor.name+" ]"+"  methods **********************\n")
  reflectMeths(lay);
