获取Obj上的所有public属性，可以用于两个对象的属性的快速匹配，详情请见 flash.utils.describeType 方法的API [codesyntax lang=”actionscript3”]

public function initParams(obj:Object):void{
this.paramVo = new ParamsVo();
var obj:Object = getVariablesMapObj(paramVo);
for(var i:String in obj){
trace(i);
if(obj.hasOwnProperty(i)){
paramVo[i] = obj[i];
}
}
}

/**
* 获得变量地图
* @param target
* @return
*
*/
private function getVariablesMapObj(target:Object):Object
{
var obj:Object = new Object();
var dt:XML=describeType(target);
for each(var node:XML in dt.variable)
{
obj[node.@name] = node.@type;
}
return obj;
}

相信大家对滤镜这东西，在flash IDE内应用很熟吧？但是在as内怎么用代码实现呢？这个问题还别说，起初真有点犯难，后经高手指点，逐一化解。经验不敢独享，故与大家分享(高手可掠过)。如有疑问，请多多提出咯……   import fl.motion.ColorMatrix; import flash.filters.ColorMatrixFilter;   //**调整亮度**// var ld_Matrix:ColorMatrix=new ColorMatrix(); var ld_Filter:ColorMatrixFilter=new ColorMatrixFilter(); ld_Matrix.SetBrightnessMatrix(100);  //设置亮度值，值的大小是 -255–255   0为中间值，向右为亮向左为暗。 ld_Filter.matrix = ld_Matrix.GetFlatArray(); ld_MC.filters = [ld_Filter]; //ld_MC.filters = [];//去除滤镜   //**调整对比度**// var db_Matrix:ColorMatrix=new ColorMatrix(); var db_Filter:ColorMatrixFilter=new ColorMatrixFilter(); db_Matrix.SetContrastMatrix(255);  //设置对比度值，值的大小是 -255–255  127.5为中间值，向右对比鲜明向左对比偏暗。 db_Filter.matrix = db_Matrix.GetFlatArray(); db_MC.filters = [db_Filter]; //db_MC.filters = [];//去除滤镜   //**调整饱和度**// var bh_Matrix:ColorMatrix=new ColorMatrix(); var bh_Filter:ColorMatrixFilter=new ColorMatrixFilter(); bh_Matrix.SetSaturationMatrix(0);  //设置饱和度值，值的大小是 -255–255   1为中间值，0为灰度值（即黑白相片）。 bh_Filter.matrix = bh_Matrix.GetFlatArray(); bh_MC.filters = [bh_Filter]; //bh_MC.filters = [];//去除滤镜   //**调整色相**// var sx_Matrix:ColorMatrix=new ColorMatrix(); var sx_Filter:ColorMatrixFilter=new ColorMatrixFilter(); sx_Matrix.SetHueMatrix(1);  //设置色相值，值的大小是 -255–255  0为中间值，向右向左一试便知。 sx_Filter.matrix = sx_Matrix.GetFlatArray(); sx_MC.filters = [sx_Filter]; //sx_MC.filters = [];//去除滤镜   原文链接：http://bbs.9ria.com/space.php?uid=112507&do=blog&id=12944
