javascript笔记:拷贝出腾讯微博关于London2012奥运会的拉绳开关的网页特效

2012-08-07 13:13 661 查看
  奥运会正在进行中,各大网站都因为这盛会有所改版或者是拿出了自己的新的页面特效。其中最牛叉的还是谷歌,如下图:



  可以用键盘控制的小游戏,看看它的源码:

<div id="hplogo" tabindex="0" dir="ltr" aria-label="跨栏" style="cursor: pointer;">
<canvas style="position: absolute;" height="207" width="530"></canvas>
.....


  canvas,html5....,拷贝它的代码还是有点难度了。

  但是我在国外的网站里还是发现了一个我感兴趣的特效,就是腾讯微博里的"拉绳开关"的换肤效果,这个比较简单,我把代码“抠 ”了出来。







  首先介绍小这个网页特效的效果,点击“London 2012”吊环图标,图标会下拉绳,释放鼠标后,页面背景会换成中国奥运军团的图 片,此时吊环下方,会有一个“还原”按钮,点击“还原”按钮,背景恢复到原来背景,继续点击拉绳吊环,背景图片会在不同的 奥运图片间切换,鼠标移到拉绳上方,鼠标变成剪刀样式,点击,吊环会以自由落体的方式坠落,最后消失。

  以上效果我都拷贝出来了,还是比较简单的,源码如下:

  首先还是目录结构:



  main.css的代码:

body {
background-color:#999;
color: #333333;
font: 12px/1.75 Tahoma,Arial,sans-serif;
}
body {
background:url(../images/wrapbg_v0.0.1.jpg) no-repeat scroll center top #73CFF1;
color: #333333;
font: 12px/1.75 Tahoma,Arial,sans-serif;
height: 100%;
}
body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, form, input, textarea, p, blockquote, th, td {
margin: 0;
padding: 0;
}
.nv_toogle_w {
height: 0;
margin: 0 auto;
position: relative;
width: 960px;
}
a, .c_tx {
text-decoration: none;
}
a, .c_tx {
color: #006A92;
}
.nv_toggle_btn, .nv_arrow_wpd, .nv_arrow_lab, .nv_arrow_message {
background:url(../images/guide_icon.png) no-repeat scroll 0 0 transparent;
}
.nv_toggle_btn {
background-position: -195px 0;
cursor: pointer;
display: block;
height: 111px;
position: absolute;
right: -31px;
text-indent: -9999px;
top: -35px;
width: 23px;
z-index: 5;
}
.nv_toggle_btn_oly2012 {
background: url("../images/nv_toggle_btn_oly2012.png") no-repeat scroll 0 0 transparent;
height: 206px;
right: -44px;
top: -73px;
width: 29px;
}
.headWrap a {
color: #C9C9C9;
}
.headWrap a:hover {
text-decoration: none;
}
.nv_toggle_btn span {
display: block;
}
.nv_toggle_reset {
color: #FECCF3 !important;
position: absolute;
right: -43px;
top: 138px;
}
.nv_toggle_reset, .nv_toggle_reset span, .nv_toggle_reset b {
display: block;
height: 26px;
width: 27px;
}
.nv_toggle_reset span {
cursor: pointer;
line-height: 26px;
position: relative;
text-align: center;
z-index: 5;
}
.nv_toggle_reset b {
background: none repeat scroll 0 0 #E33194;
left: 0;
opacity: 0.63;
position: absolute;
top: 0;
z-index: 0;
}
.nv_toggle_cut {
cursor: url("http://mat1.gtimg.com/www/mb/images/cut_c.cur"), pointer;
display: block;
height: 19px;
position: absolute;
right: -44px;
top: 0;
width: 29px;
z-index: 10;
}


  main.js的代码:

var picInd = 0;
$(document).ready(function() {
$("#nv_toogle_w").bind("mousedown",function(){
$(this).animate({top:"20px"},"normal");
});
$("#nv_toogle_w").bind("mouseup",function(){
getRandomNum();
$("body").attr("class","");
$("body").addClass("body" + picInd);
$(this).animate({top:"0px"},"normal");
$("#nv_toogle_w2").css("display","block");
});
$("#nv_toogle_w2").bind("click",function(){
$("body").attr("class","");
$("#nv_toogle_w2").css("display","none");
});
$("#nv_toggle_cut").bind("click",function(){
$("#nv_toogle_w").animate({top:"300px"},"4000");
$("a[boss='btnWideGuideBtn']").animate({opacity:"0"},"3000");
$("#nv_toogle_w2").css("display","none").delay(6999);
});
});

function getRandomNum(){
while(true){
var curInd = Math.floor(Math.random() * 8 + 1);
if (picInd != 0 || picInd != curInd){
picInd = curInd;
break;
}
}
}
