});
var goTo = $(".con");

var index = 0;
var direct = 0;
var goToFun = function() {
var len = document.getElementById("box"+index).offsetTop-30; //获取div层到页面顶部的高度
direct = 0;
if (index < 0) {
index = 0;
return;
}
if (index >= guideLi.size()) {
index = guideLi.size() - 1;
return;
}
$("html,.tree").stop().animate({scrollTop: len}, 300, "swing", function() {

});
guideLi.removeClass("on").eq(index).addClass("on");
}
guideLi.each(function(i) {
$(this).click(function() {

})
});
/* 滚轮事件 */
var scrollFunc = function(e) {

if (e.wheelDelta) {

} else if (e.detail) {

}
var first=document.getElementById("first").val();
if (direct >= first) {
goToFun(index++);
}
if (direct <= 0-first) {
goToFun(index--);
}
};
});
</script>
