Jquery. mousewheel implements the screen flip effect on the whole screen. jquery. mousewheel

Achieve the full screen flip effect:
Js to be loaded

<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script><script type="text/javascript" src="js/jquery.mousewheel.js"></script>

The css style is as follows:

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;}

The jquery code is as follows:

Var page = 0; // The Screen flip variable. The initial screen is var shakStaute = 0; // This variable acts as a jitter when the mouse pulley is sliding down or up. $ (function () {var starttime = 0, endtime = 0; $ ("body "). mousewheel (function (event, delta) {starttime = new Date (). getTime (); // record the initial time of screen flip if (delta <0 & page> = 0 & page <= $ (". content. divsame "). length-2) {if (shakStaute> = 0 & (starttime = 0 | (endtime-starttime) <=-500 )) {// execute a screen flip shakStaute = 1; page ++; renderPage (page, true) within ms; // The Screen flip function endtime = new Date (). getTime (); // record the screen flip end time} 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 "2.16.css ({'height': div_height}); $ ('. content '). animate ({top:-page * div_height}, 100) ;}); $ (". left_fixed ul li "). on ("click", function () {// click the navigation bar and run 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}, 'low'); $ (". left_fixed ul li "). removeClass ("active"); $ (". left_fixed ul li "). eq (pageNumber ). addClass ("active") ;}return ;}})

It is also a real-time response.

Let's look at an example.

Pay attention to the index. js implemented by js, jquery library, and mousewheel. js loaded in the header.

<!doctype html>
The jquery code is as follows (index. js ):
Var I = 0; // The Screen flip variable. The initial screen is var s = 0; // This variable acts as a jitter when the mouse pulley is sliding down or up. $ (function () {var starttime = 0, endtime = 0; $ ("body "). mousewheel (function (event, delta) {starttime = new Date (). getTime (); // record the initial time of screen flip if (delta <0 & I> = 0 & I <= 2) {if (s> = 0 & (starttime = 0 | (endtime-starttime) <=-500 )) {// perform screen flip s = 1 within ms; I ++; renderPage (I, true); // The Screen flip function endtime = new Date (). getTime (); // record the screen flip end time} 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 "pai.css ({'height': div_height}) ;}); function renderPage (pageNumber, isScroll) {if (isScroll) {$ ('body, html '). animate ({scrollTop: pageNumber * div_height}, 'low'); $ (". left_fixed ul li "). removeClass ("active"); $ (". left_fixed ul li "). eq (pageNumber ). addClass ("active") ;}return ;}$ (". left_fixed ul li "). on ("click", function () {// click the navigation bar and run var index = $ (this ). index (); renderPage (index, true); $ (". left_fixed ul li "). removeClass ("active"); $ (this ). addClass ("active"); return false ;});})
