拷貝出騰訊微博關(guān)于奧運會的拉繩開關(guān)特效
奧運會正在進(jìn)行中,各大網(wǎng)站都因為這盛會有所改版或者是拿出了自己的新的頁面特效。其中最牛叉的還是谷歌,如下圖:
可以用鍵盤控制的小游戲,看看它的源碼:
- <div id="hplogo" tabindex="0" dir="ltr" aria-label="跨欄" style="cursor: pointer;">
 - <canvas style="position: absolute;" height="207" width="530"></canvas>
 - .....
 
canvas,html5....,拷貝它的代碼還是有點難度了。
但是我在國外的網(wǎng)站里還是發(fā)現(xiàn)了一個我感興趣的特效,就是騰訊微博里的"拉繩開關(guān)"的換膚效果,這個比較簡單,我把代碼“摳 ”了出來。
  


首先介紹小這個網(wǎng)頁特效的效果,點擊“London 2012”吊環(huán)圖標(biāo),圖標(biāo)會下拉繩,釋放鼠標(biāo)后,頁面背景會換成中國奧運軍團(tuán)的圖 片,此時吊環(huán)下方,會有一個“還原”按鈕,點擊“還原”按鈕,背景恢復(fù)到原來背景,繼續(xù)點擊拉繩吊環(huán),背景圖片會在不同的 奧運圖片間切換,鼠標(biāo)移到拉繩上方,鼠標(biāo)變成剪刀樣式,點擊,吊環(huán)會以自由落體的方式墜落,最后消失。
以上效果我都拷貝出來了,還是比較簡單的,源碼如下:
首先還是目錄結(jié)構(gòu):

main.css的代碼:

main.js的代碼:

 - $("#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;
 - }
 - }
 - }
