目前我使用simplefadeslideshow（http://www.simplefadeslideshow.com/）来做一些淡入淡出效果。
我想要做的是，在网页上悬停某些元素时，是将幻灯片更改为某个图片。
我尝试了以下内容：
var slider_1 = jQuery('#slide_show_1').fadeSlideShow({
width: 285,
height: 489,
PlayPauseElement: false,
NextElement: false,
PrevElement: false,
ListElement: false,
});
初始化滑块，并按预期工作。然后我打电话给：
slider_1.jumpTo(2);
在悬停事件中（在第3张幻灯片中淡入淡出），返回
未捕获TypeError：对象[object Object]没有方法'jumpTo'
脚本确实有一个jumpTo（）函数，所以我称之为错误？任何帮助表示赞赏！
我尝试调用该方法的原始脚本如果有帮助：
jQuery.fn.fadeSlideShow = function(options) {
return this.each(function(){
settings = jQuery.extend({
width: 640, // default width of the slideshow
height: 480, // default height of the slideshow
speed: 'slow', // default animation transition speed
interval: 3000, // default interval between image change
PlayPauseElement: 'fssPlayPause', // default css id for the play / pause element
PlayText: 'Play', // default play text
PauseText: 'Pause', // default pause text
NextElement: 'fssNext', // default id for next button
NextElementText: 'Next >', // default text for next button
PrevElement: 'fssPrev', // default id for prev button
PrevElementText: '< Prev', // default text for prev button
ListElement: 'fssList', // default id for image / content controll list
ListLi: 'fssLi', // default class for li's in the image / content controll
ListLiActive: 'fssActive', // default class for active state in the controll list
addListToId: false, // add the controll list to special id in your code - default false
