实现整屏上下翻效果:
需加载的js
<script type=\"text/javascript\" src=\"js/jquery-1.8.3.min.js\"></script> <script type=\"text/javascript\" src=\"js/jquery.mousewheel.js\"></script>
css样式如下:
body{padding:0;margin:0; overflow:hidden }
ul{list-style:none;}
.content{width:100%;height100%;position:relative;top:0;}
.div_01,.div_02,.div_03,.div_04{width:100%;margin:0 auto; text-align: center;}
.div_01{background: #b20909;}
.div_02{background: #0941b2;}
.div_03{background: #2db209;}
.div_04{background: #b29c09;}
.left_fixed{position:fixed;width:15px; height:100px; left:100px;top:200px;z-index:999;}
.left_fixed ul li{
background:#000;cursor:pointer;width:15px;height: 15px;
border-radius:15px;margin-bottom: 10px;
}
.left_fixed ul li.active{background:#fff;}
jquery代码如下:
var page=0;//翻屏变量,初始第一屏
var shakStaute = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象
$(function(){
var starttime = 0,
endtime = 0;
$(\"body\").mousewheel(function(event, delta) {
starttime = new Date().getTime(); //记录翻屏的初始时间
if (delta < 0&& page>=0 && page<=$(\".content .divsame\").length-2) {
if (shakStaute>=0 &&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏
shakStaute=1;
page++;
renderPage(page,true); //翻屏函数
endtime = new Date().getTime(); //记录翻屏的结束时间
}
} else if (delta>0 && page>=1 && shakStaute==1 && (starttime == 0 || (endtime - starttime) <= -500)) {
page--;
renderPage(page,true);
endtime = new Date().getTime();
}
});
var div_height=$(window).height();
$(\".divsame\").css({\'height\':div_height});
$(window).resize(function(){
div_height=$(window).height();
$(\".divsame\").css({\'height\':div_height});
$(\'.content\').animate({top:-page*div_height }, 100);
});
$(\".left_fixed ul li\").on(\"click\", function(){ //点击小导航也执行翻屏
var index = $(this).index();
if(index>0){
shakStaute==1;
}
page = index;
renderPage(page, true);
$(\".left_fixed ul li\").removeClass(\"active\");
$(this).addClass(\"active\");
return false;
});
function renderPage(pageNumber, isScroll){
if (isScroll){
$(\'.content\').animate({top:-pageNumber*div_height }, \'slow\');
$(\".left_fixed ul li\").removeClass(\"active\");
$(\".left_fixed ul li\").eq(pageNumber).addClass(\"active\");
}
return;
}
})
同时也是实时响应的。
再来看一个例子
注意头部加载的js,jquery库,mousewheel.js已经实现的index.js
<!doctype html>
<html>
<head>
<meta charset=\"utf-8\">
<title></title>
<meta name=\"keywords\" content=\"\"/>
<meta name=\"description\" content=\"\"/>
<script type=\"text/javascript\" src=\"js/jquery-1.8.3.min.js\"></script>
<script type=\"text/javascript\" src=\"js/jquery.mousewheel.js\"></script>
<script type=\"text/javascript\" src=\"js/index.js\"></script>
<style>
body{padding:0;margin:0; overflow:hidden }
ul{list-style:none;}
.div_01,.div_02,.div_03,.div_04{width:100%;margin:0 auto; text-align: center;}
.div_01{background: #b20909;}
.div_02{background: #0941b2;}
.div_03{background: #2db209;}
.div_04{background: #b29c09;}
.left_fixed{position:fixed;width:15px; height:100px; left:100px;top:200px;z-index:999;}
.left_fixed ul li{background:#000;cursor:pointer;width:15px;height: 15px;border-radius:15px;margin-bottom: 10px;}
.left_fixed ul li.active{background:#fff;}
</style>
</head>
<body>
<div class=\"content\">
<div class=\"div_01\"></div>
<div class=\"div_02\"></div>
<div class=\"div_03\"></div>
<div class=\"div_04\"></div>
</div>
<div class=\"left_fixed\">
<ul>
<li class=\"active\"></li>
<li></li>
<li></li>
<li></li>
</ul>
</div>
</body>
</html>
jquery 代码如下(index.js):
var i=0;//翻屏变量,初始第一屏
var s = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象
$(function(){
var starttime = 0,
endtime = 0;
$(\"body\").mousewheel(function(event, delta) {
starttime = new Date().getTime(); //记录翻屏的初始时间
if (delta < 0&& i>=0 && i<=2) {
if (s>=0&&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏
s=1;
i++;
renderPage(i,true); //翻屏函数
endtime = new Date().getTime(); //记录翻屏的结束时间
}
} else if (delta > 0&& i>=1&&s==1&& (starttime == 0 || (endtime - starttime) <= -500)) {
i--;
//console.log(i);
renderPage(i,true);
endtime = new Date().getTime();
}
});
var div_height=$(window).height();
$(\".div_01,.div_02,.div_03,.div_04\").css({\'height\':div_height});
$(window).resize(function(){
var div_height=$(window).height();
$(\".div_01,.div_02,.div_03,.div_04\").css({\'height\':div_height});
});
function renderPage(pageNumber, isScroll){
if (isScroll){
$(\'body, html\').animate({scrollTop:pageNumber*div_height }, \'slow\');
$(\".left_fixed ul li\").removeClass(\"active\");
$(\".left_fixed ul li\").eq(pageNumber).addClass(\"active\");
}
return;
}
$(\".left_fixed ul li\").on(\"click\", function(){ //点击小导航也执行翻屏
var index = $(this).index();
renderPage(index, true);
$(\".left_fixed ul li\").removeClass(\"active\");
$(this).addClass(\"active\");
return false;
});
})
