使用方法
使用该签名插件要引入jQuery文件。
<script src="jquery/1.11.0/jquery.min.js"></script>
HTML结构
下面是该图片墙特效的基本HTML结构:
<div class="wrap" id="wrap"> <div class="photo photo_front" id="photo_{{index}}" onclick="turn(this)"> <div class="photo-wrap"> <div class="side side-front"> <p class="image"><img src="photo/{{img}}"></p> <p class="caption">{{caption}}</p> </div> <div class="side side-back"> <p class="desc">{{desc}}</p> </div> </div> </div> </div>
在你的图片文件夹中放置你自己的图片,然后在该文件夹下创建一个data.js文件。该文件用于描述图片的数据,代码如下:
var data = []; var dataStr = "1.DeathNote<br>/ <br>/ ** Cartoon<br>/ <br>/ <br>/ 2.FateUBW<br>/ <br>/ ** Cartoon<br>/ <br>/ <br>/ 3.FateZero<br>/ <br>/ ** Cartoon<br>/ " var d = dataStr.split("<br><br><br>"); for(var i = 0; i<d.length; i++){ var c = d[i].split("<br><br>"); data.push({ img: c[0]+ ".jpg", caption: c[0].split(".")[1], desc: c[1] }); }
CSS样式
该照片墙的基本CSS样式如下:
.wrap { width: 100%; height: 600px; position: absolute; top: 50%; margin-top: -300px; background-color: #333; overflow: hidden; -webkit-perspective: 800px; -moz-perspective: 800px; } .photo { width: 260px; height: 320px; position: absolute; z-index: 1; box-shadow: 0 0 1px rgba(0,0,0,.01); -webkit-transition: all 0.6s; -moz-transition: all 0.6s; left: 50%; top: 50%; margin: -160px 0 0 -130px; } .photo .side { width: 100%; height: 100%; background-color: #eee; position: absolute; top: 0; right: 0; padding: 20px; box-sizing: border-box; } .photo .side-front { /*display: none;*/ } .photo .side-front .image { width: 100%; height: 250px; line-height: 250px; overflow: hidden; } .photo .side-front .image img { width: 100%; } .photo .side-front .caption { text-align: center; font-size: 16px; line-height: 50px; } .photo .side-back { } .photo .side-back .desc { color: #666; font-size: 14px; line-height: 1.5em; } .photo_center { left: 50%; top: 50%; margin: -160px 0 0 -130px; z-index: 999; } .photo-wrap { position: absolute; width: 100%; height: 100%; -webkit-transform-style: preserve-3d; -webkit-transition: all 0.6s; -moz-transform-style: preserve-3d; -moz-transition: all 0.6s; } .photo-wrap .side-front { -webkit-transform: rotateY(0deg); -moz-transform: rotateY(0deg); } .photo-wrap .side-back { -webkit-transform: rotateY(180deg); -moz-transform: rotateY(180deg); } .photo-wrap .side { -webkit-backface-visibility: hidden; -moz-backface-visibility: hidden; } .photo_front .photo-wrap { -webkit-transform: rotateY(0deg); -moz-transform: rotateY(0deg); } .photo_back .photo-wrap { -webkit-transform: rotateY(180deg); -moz-transform: rotateY(180deg); }
下面是圆点导航按钮的CSS样式。
.nav { width: 80%; height: 30px; line-height: 30px; position: absolute; left: 10%; bottom: 20px; z-index: 999; text-align: center; } .nav .i { width: 30px; height: 30px; display: inline-block; cursor: pointer; background-color: #aaa; text-align: center; border-radius: 90%; -webkit-transform: scale(0.5); -webkit-transition: all 0.5s; -moz-transform: scale(0.5); -moz-transition: all 0.5s; } .nav .i_current { -webkit-transform: scale(0.8); -moz-transform: scale(0.8); } .nav .i_back { -webkit-transform: rotateY(-180deg) scale(0.8); -moz-transform: rotateY(-180deg) scale(0.8); background-color: #555; }
初始化插件
在页面加载完成之后使用下面的代码来初始化该图片墙特效插件。
$(document).ready(function(){ addPhotos(); }); function select(selector) { var method = selector.substr(0,1) == '.' ? 'getElementsByClassName' : 'getElementById'; return document[method](selector.substr(1)); } function range() { var range = {left : {x : [], y : []}, right : {x : [], y : []}}; var wrap = { w : select("#wrap").clientWidth, h : select("#wrap").clientHeight } var photo = { w : select(".photo")[0].clientWidth, h : select(".photo")[0].clientHeight } range.wrap = wrap; range.photo = photo; range.left.x = [0, wrap.w/2 - photo.w/2]; range.left.y = [0, wrap.h - photo.w/2]; range.right.x = [wrap.w/2 + photo.w/2, wrap.w]; range.right.y = [0, wrap.h - photo.w/2]; return range; } function sort(n) { var _photo = select('.photo'); var photos = []; for(i=0; i<_photo.length; i++) { _photo[i].className = _photo[i].className.replace(//s*photo_center/s*/, ' '); _photo[i].className = _photo[i].className.replace(//s*photo_front/s*/, ' '); _photo[i].className = _photo[i].className.replace(//s*photo_back/s*/, ' '); _photo[i].className += ' photo_front'; _photo[i].style.left = ''; _photo[i].style.top = ''; _photo[i].style['transform'] = 'rotate(360deg) scale(1.3)'; _photo[i].style['-webkit-transform'] = 'rotate(360deg) scale(1.3)'; photos.push(_photo[i]); } var photo_center = select('#photo_' + n); photo_center.className += ' photo_center'; photo_center = photos.splice(n, 1)[0]; var photos_left = photos.splice(0, Math.ceil(photos.length/2)); var photos_right = photos; var ranges = range(); for(var i=0; i<photos_left.length; i++){ photos_left[i].style.left = random(ranges.left.x) + "px"; photos_left[i].style.top = random(ranges.left.y) + "px"; photos_left[i].style['transform'] = 'rotate('+random([-150,150])+'deg) scale(1)'; photos_left[i].style['-webkit-transform'] = 'rotate('+random([-150,150])+'deg) scale(1)'; } for(var i = 0; i<photos_right.length; i++){ photos_right[i].style.left = random(ranges.right.x) + "px"; photos_right[i].style.top = random(ranges.right.y) + "px"; photos_right[i].style['transform'] = 'rotate('+random([-150,150])+'deg) scale(1)'; photos_right[i].style['-webkit-transform'] = 'rotate('+random([-150,150])+'deg) scale(1)'; } var navs = select('.i'); for(var i=0; i<navs.length; i++) { navs[i].className = navs[i].className.replace(//s*i_current/s*/, ' '); navs[i].className = navs[i].className.replace(//s*i_back/s*/, ' '); } select('#nav_' + n).className += ' i_current '; } function random(range) { var max = Math.max(range[0], range[1]); var min = Math.min(range[0], range[1]); var diff = max - min; var number = Math.floor(Math.random() * diff + min); return number; } var data = data; function addPhotos() { var template = select('#wrap').innerHTML; var html = []; var nav = []; for (i=0; i<data.length; i++) { var _html = template.replace('{{index}}', i) .replace('{{img}}', data[i].img) .replace('{{caption}}', data[i].caption) .replace('{{desc}}', data[i].desc); html.push(_html); nav.push('<span id="nav_'+i+'" class="i" onclick ="turn(select(/'#photo_'+i+'/'))"> </span>'); } html.push('<div class="nav">'+nav.join('')+'</div>'); select('#wrap').innerHTML = html.join(''); sort(random([0, data.length])); } function turn(elem) { var cls = elem.className; var n = elem.id.split("_")[1]; if(! /photo_center/.test(cls)) { return sort(n); } if(/photo_front/.test(cls)) { cls = cls.replace(/photo_front/, 'photo_back'); select('#nav_' + n).className += ' i_back '; } else { cls = cls.replace(/photo_back/, 'photo_front'); select('#nav_' + n).className = select('#nav_' + n).className.replace(//s*i_back/s*/, ' '); } return elem.className = cls; }
