本文介绍了一个用于获取当前笔刷工具参数的JavaScript函数实现。通过构造ActionReference并利用不同类型的值来解析笔刷选项，该函数能够准确地读取并返回当前所选笔刷的所有属性。

1.比如获取当前笔刷工具

var param = get_brush_param();  
  
//alert(param.opacity, "Opacity");  
//alert(param.diameter, "Diameter");  
  
alert(obj_to_str(param), "Brush options");  
function obj_to_str(obj){var str = ""; for (var p in obj) if(obj.hasOwnProperty(p))try{str+=p+"::"+obj[p]+"\n";}catch(e){};
      logInfo( str);
    return str;}
