JS組件系列——圖片切換特效:簡(jiǎn)易抽獎(jiǎng)系統(tǒng)
前言:前兩天在網(wǎng)上找組件,無意中發(fā)現(xiàn)了我們兒時(shí)游戲機(jī)效果的“SlotMachine組件”,瀏覽一遍下來,勾起了博主小時(shí)候滿滿的回憶。于是下定決定要研究下這么一個(gè)東西,不得不再次嘆息開源社區(qū)的強(qiáng)大,原來這些組件已經(jīng)被封裝得這么好了,使用起來如此簡(jiǎn)單。下面就讓博主帶著大家來看看這么一個(gè)神奇的組件——SlotMachine吧。
一、組件預(yù)覽
先來一發(fā)簡(jiǎn)單的效果壓壓驚

覺得太簡(jiǎn)單?別急,好戲在后頭,試試手氣先。

什么?還沒達(dá)到想要的效果,好!下面,真實(shí)效果來一發(fā)。

博主點(diǎn)擊了好長(zhǎng)時(shí)間,都沒有中獎(jiǎng),難怪小時(shí)候怎么都贏不了呢。博主不信邪,繼續(xù)點(diǎn)擊開始,終于有一次中獎(jiǎng)的了,真心不容易。

還有我們年終抽獎(jiǎng)效果,開始!停止!

二、代碼示例
既然是js組件,肯定是先要下載組件庫(kù)。首先貼上 開源地址

然后來看看文件的引用:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous"> <link href="~/Content/jQuery-SlotMachine-master/dist/jquery.slotmachine.css" rel="stylesheet" /> <link href="~/Content/jQuery-SlotMachine-master/css/style.css" rel="stylesheet" /> <link href="~/Content/toastr/toastr.min.css" rel="stylesheet" /> <script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js" integrity="sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS" crossorigin="anonymous"></script> <script src="~/Content/jQuery-SlotMachine-master/dist/jquery.slotmachine.js"></script> <script src="~/Content/toastr/toastr.min.js"></script>
這里需要注意幾點(diǎn):
- 引用jquery和bootstrap都是通過cdn加速的方式引用的,不懂cdn加速的可以百度。
- Jquery組件必須,并且組件需要Jquery 2.0以上版本的支持,版本太低會(huì)有js異常。
- bootstrap組件并非必須,但是本篇布局需要部分bootstrap的樣式支持。
- toastr組件并非必須,此處用于顯示中獎(jiǎng)的結(jié)果。
1、試試手氣效果代碼
html部分
<div id="triky"> <div class="content" style="text-align: center"> <h1>請(qǐng)選擇你想吃的食物</h1> <div class="row"> <div style="margin: auto;"> <div id="triky1"> <div> <img src="/Content/jQuery-SlotMachine-master/img/cookie.png" /> </div> <div> <img src="/Content/jQuery-SlotMachine-master/img/food1.jpg" /> </div> <div> <img src="/Content/jQuery-SlotMachine-master/img/food2.jpg" /> </div> <div> <img src="/Content/jQuery-SlotMachine-master/img/food3.jpg" /> </div> </div> <div> <div class="btn-group btn-group-justified btn-group-triky" style="margin-left:-15px" role="group"> <div id="trikyShuffle" type="button" class="btn btn-primary btn-lg">試試手氣</div> </div> </div> </div> </div> </div> <div class="clearfix"></div> </div>
JS部分
$(function () { //試試手氣 var triky = $("#triky1").slotMachine({ active: 2, //初始化的時(shí)候顯示的項(xiàng)的索引 //delay: 150,//切換兩張圖片的間隔時(shí)間(毫秒單位) //randomize: function () { // return 0;//每次旋轉(zhuǎn)后選中值的索引(從0開始) //} }); $("#trikyShuffle").click(function () { triky.shuffle(8);//開始旋轉(zhuǎn)方法,參數(shù)8表示每次旋轉(zhuǎn)跳過8個(gè)圖標(biāo) }); });
JS常用屬性、方法、事件詳解
(1)初始化方法 var machine = $("#id").slotMachine({}); 返回當(dāng)前旋轉(zhuǎn)的對(duì)象。slotMachine()方法里面?zhèn)鬟f初始化的參數(shù),比如
- active:表示初始化的時(shí)候顯示項(xiàng)的索引,從0開始
- delay:切換兩張圖片的間隔時(shí)間(毫秒單位)
- auto:是否自動(dòng)旋轉(zhuǎn),取值為true or false
- spins:當(dāng)auto為true的時(shí)候,這是每次跳過圖標(biāo)的個(gè)數(shù)
- stophidden:是否出現(xiàn)開始和停止時(shí)候的動(dòng)畫
- randomize:function(activeElementIndex){}此屬性表示每次旋轉(zhuǎn)后選中值的索引(從0開始)
- direction:動(dòng)畫的方向,取值(up||down)
(2)常用方法
- machine.shuffle( repeat, onStopCallback ); 表示開始旋轉(zhuǎn),repeat表示每次跳過的圖片個(gè)數(shù);onstopCallback表示旋轉(zhuǎn)停止后的事件回調(diào)方法。
- machine.prev(); 返回前一個(gè)元素
- machine.next(); 返回后一個(gè)元素
- machine.stop(); 停止旋轉(zhuǎn)
- machine.active; 得到選中的元素的索引
- machine.running; 檢測(cè)是否正在旋轉(zhuǎn),true表示正在旋轉(zhuǎn)
- machine.stopping; 檢測(cè)是否已經(jīng)停止
- machine.destroy(); 摧毀旋轉(zhuǎn)節(jié)點(diǎn)
2、簡(jiǎn)單游戲機(jī)效果代碼示例
html部分
<div id="randomize"> <div class="content container" style="text-align: center;max-width: 900px;"> <h1>簡(jiǎn)易游戲機(jī)</h1> <div class="row"> <div class="col-xs-4"> <div> <div id="machine1" class="randomizeMachine"> <div><img src="/Content/jQuery-SlotMachine-master/img/slot1.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot2.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot3.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot4.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot5.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot6.png" /></div> </div> </div> </div> <div class="col-xs-4"> <div> <div id="machine2" class="randomizeMachine"> <div><img src="/Content/jQuery-SlotMachine-master/img/slot1.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot2.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot3.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot4.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot5.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot6.png" /></div> </div> </div> </div> <div class="col-xs-4"> <div> <div id="machine3" class="randomizeMachine"> <div><img src="/Content/jQuery-SlotMachine-master/img/slot1.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot2.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot3.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot4.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot5.png" /></div> <div><img src="/Content/jQuery-SlotMachine-master/img/slot6.png" /></div> </div> </div> </div> </div> <div> <div class="btn-group btn-group-justified btn-group-randomize" role="group"> <div id="ranomizeButton" type="button" class="btn btn-danger btn-lg">開始</div> </div> </div> </div> </div>
JS部分
$(function () { //簡(jiǎn)易游戲機(jī) var machine1 = $("#machine1").slotMachine({ active: 0, delay: 500 }); var machine2 = $("#machine2").slotMachine({ active: 1, delay: 500, direction: 'down' }); var machine3 = $("#machine3").slotMachine({ active: 2, delay: 500 }); var arr = []; function onComplete(active) { if (arr.length <= 1) { arr.push(active); } else if (arr.length > 1) { arr.push(active); if (arr[0] == arr[1] && arr[1] == arr[2]) { toastr.success("恭喜你中獎(jiǎng)了!"); } else if (arr[0] == arr[1] || arr[0] == arr[2] || arr[1] == arr[2]) { toastr.success("還差一點(diǎn),繼續(xù)加油"); } else { toastr.success("手氣不行"); } arr = []; } } $("#ranomizeButton").click(function () { machine1.shuffle(5, onComplete); setTimeout(function () { machine2.shuffle(5, onComplete); }, 500); setTimeout(function () { machine3.shuffle(5, onComplete); }, 1000); }) });
3、單個(gè)停止效果代碼示例
Html部分
<div id="casino" style="padding-top:50px;"> <div class="content"> <h1>抽獎(jiǎng)</h1> <div> <div id="casino1" class="slotMachine" style="margin-left: -65px;"> <div class="slot slot1"></div> <div class="slot slot2"></div> <div class="slot slot3"></div> <div class="slot slot4"></div> <div class="slot slot5"></div> <div class="slot slot6"></div> </div> <div id="casino2" class="slotMachine"> <div class="slot slot1"></div> <div class="slot slot2"></div> <div class="slot slot3"></div> <div class="slot slot4"></div> <div class="slot slot5"></div> <div class="slot slot6"></div> </div> <div id="casino3" class="slotMachine"> <div class="slot slot1"></div> <div class="slot slot2"></div> <div class="slot slot3"></div> <div class="slot slot4"></div> <div class="slot slot5"></div> <div class="slot slot6"></div> </div> <div class="btn-group btn-group-justified btn-group-casino" role="group"> <div id="slotMachineButtonShuffle" type="button" class="btn btn-primary btn-lg">開始</div> <div id="slotMachineButtonStop" type="button" class="btn btn-primary btn-lg">停止</div> </div> </div> </div> <div class="clearfix"></div> </div>
JS部分
$(function () { //單個(gè)停止 var machine4 = $("#casino1").slotMachine({ active: 0, delay: 500 }); var machine5 = $("#casino2").slotMachine({ active: 1, delay: 550 }); machine6 = $("#casino3").slotMachine({ active: 2, delay: 600 }); var started = 0; $("#slotMachineButtonShuffle").click(function () { started = 3; machine4.shuffle(); machine5.shuffle(); machine6.shuffle(); }); $("#slotMachineButtonStop").click(function () { switch (started) { case 3: machine4.stop(); break; case 2: machine5.stop(); break; case 1: machine6.stop(); break; } started--; }); });
三、總結(jié)
整個(gè)過程并不復(fù)雜,所有的屬性、事件、方法基本看看文檔都能很好理解運(yùn)用,演示代碼也沒什么好說的,一看就懂。組件本身在一般的系統(tǒng)里面可能很難有用武之地,本篇作為懷舊之作,以此來紀(jì)念我們已經(jīng)逝去的童年。原來制作一個(gè)這種簡(jiǎn)單游戲如此easy,下次年會(huì),你都可以做一個(gè)抽獎(jiǎng)系統(tǒng)了,只要有圖片素材,一個(gè)字:簡(jiǎn)單。至此,本篇基本結(jié)束。如果本篇也引起了你的共鳴,不妨推薦哈,歡迎園友拍磚~~
