使用JS模拟实现掷色子效果,并显示结果,可以用来做论坛,网站上面的小游戏功能模块,

其实实现这样的JS动画效果的原理很简单的,我们要用到一张图片素材,然后用脚本控制图处的显示位置即可,代码如下:

<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>jQuery掷色子并显示随机结果</title> <style type="text/css"> .demo { width: 760px; height: 120px; margin: 10px auto; } .wrap { width: 90px; height: 90px; margin: 120px auto 30px auto; position: relative; } .dice { width: 90px; height: 90px; background: url(http://www.jiniannet.com/Attachment/20168) no-repeat; cursor: pointer; } .dice_1 { background-position: -5px -4px; } .dice_2 { background-position: -5px -107px; } .dice_3 { background-position: -5px -212px; } .dice_4 { background-position: -5px -317px; } .dice_5 { background-position: -5px -427px; } .dice_6 { background-position: -5px -535px; } .dice_t { background-position: -5px -651px; } .dice_s { background-position: -5px -763px; } .dice_e { background-position: -5px -876px; } p#result { text-align: center; font-size: 16px; } p#result span { font-weight: bold; color: #f30; margin: 6px; } #dice_mask { width: 90px; height: 90px; background: #fff; opacity: 0; position: absolute; top: 0; left: 0; z-index: 999; } </style> <script type="text/javascript" src="/Resources/Script/JQuery.js"></script> <script type="text/javascript"> $(function () { var dice = $("#dice"); dice.click(function () { $(".wrap").append("<div id='dice_mask'></div>");//加遮罩 dice.attr("class", "dice");//清除上次动画后的点数 dice.css('cursor', 'default'); var num = Math.floor(Math.random() * 6 + 1);//产生随机数1-6 dice.animate({ left: '+2px' }, 100, function () { dice.addClass("dice_t"); }).delay(200).animate({ top: '-2px' }, 100, function () { dice.removeClass("dice_t").addClass("dice_s"); }).delay(200).animate({ opacity: 'show' }, 600, function () { dice.removeClass("dice_s").addClass("dice_e"); }).delay(100).animate({ left: '-2px', top: '2px' }, 100, function () { dice.removeClass("dice_e").addClass("dice_" + num); $("#result").html("您掷得点数是<span>" + num + "</span>"); dice.css('cursor', 'pointer'); $("#dice_mask").remove();//移除遮罩 }); }); }); </script> </head> <body> <div id="main"> <h2 class="top_title">jQuery掷色子并显示随机结果</h2> <div class="demo"> <div class="wrap"> <div id="dice" class="dice dice_1"></div> </div> <p id="result">请直接点击上面的色子!</p> </div> </div> </body> </html>
