clientX Property Internet Development Index --------------------------------------------------------------------------------Sets or retrieves the x-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.Syntaxevent.clientX [ = iXPos ] Possible ValuesiXPos Integer that specifies or receives the x-coordinate, in pixels. The property is read/write. The property has no default value.Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.ResThe property is read-only in Microsoft® Internet Explorer 4.0, and read/write in Internet Explorer 5 and later.Because the clientX property returns a value relative to the client, you can add the value of the scrollLeft property to determine the distance of the x-coordinate from the edge of the body element. Within a viewlink, the client area begins at the edge of the master element. ExampleThis example uses the clientX property to determine the mouse position relative to the window.

x Property Internet Development Index --------------------------------------------------------------------------------Sets or retrieves the x-coordinate, in pixels, of the mouse pointer's position relative to a relatively positioned parent element.Syntaxevent.x [ = iX ] Possible ValuesiX Integer that specifies or receives the x-coordinate, in pixels. The property is read/write. The property has no default value.Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.ResThe property is read-only in Microsoft® Internet Explorer 4.0, and read/write in Internet Explorer 5 and later.In browser versions earlier than Internet Explorer 5, the x property retrieves a coordinate relative to the client.This property returns the x-coordinate of the closest relatively positioned parent element of the element that fires the event. If the event firing element is relatively positioned, then the x-coordinate from the boundary of the element is returned. If the event firing element and all of its parent elements are not relatively positioned, then the x property returns a coordinate relative to the body element.If the mouse is outside the window when the event is called, this property returns -1.ExampleThis example displays the current mouse position in the browser's status window.<BODY onmousemove="window.status = 'X=' + window.event.x + ' Y=' + window.event.y"> Standards InformationThere is no public standard that applies to this property.
对于坐标相关的属性，也不多吧，就那么十几个。查看手册的时候，注意查看的方法还是比较重要的。
这个搞定了，再看看event.

我找到答案了。这个文章讲的很详细,他内含一个程序,对于测试很有好处.
我际修改了一点可以动态获取各种属性,谁要可以给我留言
谢谢大家了。
