我有HTML应用程序，有人为用于滚动的JavaScript编写了javascript库。现在我想滚动到该库的特定div，我不必使用location.href或`location.hash``我必须使用JS库执行此操作，代码是这样的。
var ScrollPage = BGBiRepScroller.ScrollPage = function(){
this.animationFunList = [];
}
ScrollPage.prototype = {
$el:null,
$sectionList:null,
sectionPositionsY:null,
startTouchY:0,
startScrollY:0,
initTop:0,
endTouchY:0,
endDistance:0,
acceleration:8,
containerHeight:600,
currentSectionIndex:0,
isScrolling:false,
snapSection:true,
create: function($tEl){
this.$el = $tEl;
this.sectionPositionsY = new Array();
this.$sectionList = this.$el.find(".scrollSection");
var $origParent = this.$el.parent();
var $tempHolder = $("<div></div>");
$("body").append($tempHolder);
$tempHolder.css("opacity",0);
$tempHolder.append(this.$el);
this.$el.transition({ y: 0},0);
if(this.$sectionList.length>0){
this.initTop = this.$sectionList.position().top;
console.log("this.initTop::" + this.initTop);
for(var i=0; i<this.$sectionList.length; i++){
this.sectionPositionsY.push($(this.$sectionList[i]).position().top);
console.log($(this.$sectionList[i]).position().top);
}
}
$origParent.prepend(this.$el);
$tempHolder.remove();
this.createTouchEvents();
},
createTouchEvents: function(){

现在点击div部分我想移动到特定部分
$('.purple li').click(function(e)
{
//SOMETHING
});
我怎么能实现这一点请有人帮忙
