jQuery特效js
$(function(){
$(".btn").hover(function(){
$(this).find(".first").addClass("focus")
},function(){
$(this).find(".first").removeClass("focus")
})
$(document).scroll(function(){
var tops=$(this).scrollTop();
if(tops>=200){
$("ul").show(700)
}else{
$("ul").hide(700)
}
$(".mainbox").each(function(i,o){
var bTop=$(o).offset().top;
if(tops>=bTop){
$(".first").removeClass("active").eq(i).addClass("active")
}
})
})
$(".btn").click(function(){
var index=$(this).index();
var topss=$(".mainbox").eq(index).offset().top;
$("html,body").stop().animate({scrollTop:topss},800)
})
$(".last").click(function(){
$("html,body").stop().animate({scrollTop:0},800)
})
})
最后在引入本地jQuery文件或者外部引用
