Question

我正在编辑我的Jquery Scroll Up脚本，它工作得很完美，但是当我试图在悬停时更改图像时发现错误，这是我的博客

这是我的滚动脚本中有问题的一部分

    controlHTML: '<img src="http://2.bp.blogspot.com/-onAd5CVV5QM/UBzbWeBr88I/AAAAAAAAACI/TPBsgVOiEzg/s1600/arrowhover.png" style="width: 55px; height: 54px; " />',

我想改变这个形象

使用此图片

仅在悬停时，

注意： 我知道如何在HTML＆amp ;;中更改鼠标悬停时的图像Jquery，但在这种情况下不起作用，我认为由于控制脚本标签中的HTML，因为你知道如何解决它？或者如果你有任何其他更好的脚本在Jquery中向上滚动？如果你有......请将它交给我：）

我正在使用这个脚本来改变悬停时的图像，它的工作方式却不起作用!!

这是我的整个Scroll Up脚本，如果你wana审查它..

<script type="text/javascript" >
var scrolltotop={ 
    //startline: Integer. Number of pixels from top of doc scrollbar is scrolled before showing control 
    //scrollto: Keyword (Integer, or "Scroll_to_Element_ID"). How far to scroll document up when control is clicked on (0=top).

            $(window).bind('scroll resize', function(e){
