将FormPanel设置autoScroll:true后,如何得到滚动条的位置,并设置其滚动位置
[b]问题补充:[/b]
无法实现,页面明明有滚动条可用isScrollable判读为false,alert(getScroll对象)是{left:0,top:0} 而且scroll和scrollTo方法也不会有反映,你验证过吗?能给个实际的方法,别Ctrl+C Element API行吗?

FormPanel.el.getScroll();//得到滚动条对象
//对象内容 {left:(scrollLeft),top:(scrollTop)}
an object containing the scroll position in the format {left: (scrollLeft), top: (scrollTop)}FormPanel.el.isScrollable();//判断对象是否可以滚动
scroll(方向,滚动多少,是否动画);
scroll( String direction, Number distance, [Boolean/Object animate] ) : BooleanScrolls this element the specified direction. Does bounds checking to make sure the scroll is within this element's scrollable range.
Parameters:* direction : String 方向参数 l:左边滚动 ,r:右边滚动, t:上边滚动, b:下滚动 Possible values are: "l" (or "left"), "r" (or "right"), "t" (or "top", or "up"), "b" (or "bottom", or "down"). * distance : Number How far to scroll the element in pixels * animate : Boolean/Object (optional) true for the default animation or a standard Element animation config object
Returns:
* Boolean Returns true if a scroll was triggered or false if the element was scrolled as far as it could go.
scrollIntoView( [Mixed container], [Boolean hscroll] ) : Ext.Element
scrollTo(往哪滚动,滚动多少,动画否);
scrollTo( String side, Number value, [Boolean/Object animate] ) : ElementScrolls this element the specified scroll point. It does NOT do bounds checking so if you scroll to a weird value it will try to do it. For auto bounds checking, use scroll().
Parameters:* side : String Either "left" for scrollLeft values or "top" for scrollTop values. * value : Number The new scroll value * animate : Boolean/Object (optional) true for the default animation or a standard Element animation config object
Returns:
* Element this
