1、错误描述

此行的多个标记:
-1118: 属于 static 类型 Object 的值的隐式强制指令的目标可能是非相关类型 Number。
-left

2、错误原因

/**
 * 刷新按钮函数
 */
protected function refresh_clickHandler(event:MouseEvent):void
{
     var hx:Number = hsb.left;
     var hy:Number = hsb.y;

     //var dx:Number = dataGrid.contentMouseX;
     //var dy:Number = dataGrid.contentMouseY;
     //Alert.show("hx："+hx+"\n"+"hy: "+hy + "\n" + "dx: " + dx + "\n" + "dy: " + dy);
     Alert.show("hx："+hx+"\n"+"hy: "+hy);
}

<s:HScrollBar id="hsb" width="100%" viewport="{dataGrid}"/>

将hx由数字类型转换成Object

3、解决办法

/**
 * 刷新按钮函数
 */
protected function refresh_clickHandler(event:MouseEvent):void
{
     var hx:Object = hsb.left;
     var hy:Number = hsb.y;

     //var dx:Number = dataGrid.contentMouseX;
     //var dy:Number = dataGrid.contentMouseY;
     //Alert.show("hx："+hx+"\n"+"hy: "+hy + "\n" + "dx: " + dx + "\n" + "dy: " + dy);
     Alert.show("hx："+hx+"\n"+"hy: "+hy);
}
