jQuery+PHP实现的掷色子抽奖游戏实例
这篇文章主要介绍了jQuery+PHP实现的掷色子抽奖游戏,较为详细的分析了掷色子抽奖游戏的完整实现步骤与各个环节的实现技巧,具有一定参考借鉴价值,需要的朋友可以
本文实例讲述了jQuery+PHP实现的掷色子抽奖游戏详细步骤。分享给大家供大家参考。具体分析如下:
该游戏是以大富翁游戏为背景,综合运用jQuery和PHP知识,设计出以掷色子点数来达成抽奖的效果,当然抽奖概率是可控的,开发者可以将本实例稍作修改即可运用到网站中的抽奖活动场景中。效果图如下:

HTML部分:
首先我们需要准备两粒色子和奖品素材,这些作者已经打包上传了,请大家放心下载。我们将在html页面中写下如下的html结构代码,,.wrap用来放置色子和提示信息,#prize则是用来放置奖品的。
复制代码 代码如下:
CSS部分:
我们要用CSS技术来将页面布局合理规范化,我们将奖品围成一个矩形,共10个位置,将两粒色子定位在矩形的中央,抽奖时可以直接点击中间的色子。这些我们可以用CSS的定位技术来实现页面布局。
复制代码 代码如下:
.demo{width:650px; height:420px; margin:60px auto 10px auto; position:relative; }
.wrap{width:200px; height:100px; position:absolute; margin-left:220px; margin-top:140px; z-index:1000;}
#msg{display:none;width:50px; height:20px; padding:4px; background:#ffc; border:1px solid #fc9;
text-align:center; color:#f30; font-size:18px; position:absolute; z-index:1001; right:-20px; top:-10px}
.dice{width:90px; height:90px; display:block; float:left; background:url(dice.png) no-repeat; cursor:pointer}
#dice_mask{width:200px; height:100px; background:#fff; opacity:0; position:absolute; top:0; left:0; z-index:999}
.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}
#prize{position:relative}
#prize li{position:absolute; width:150px; height:112px; border:1px solid #d3d3d3}
#d_0{left:0; top:0}
#d_1{left:160px; top:0}
#d_2{left:320px; top:0}
#d_3{left:480px; top:0}
#d_4{left:480px; top:128px}
#d_5{left:480px; top:256px}
#d_6{left:320px; top:256px}
#d_7{left:160px; top:256px}
#d_8{left:0; top:256px}
#d_9{left:0; top:128px}
.mask{opacity: 0.6; width:150px; height:112px; line-height:32px; background:#ffc;
z-index:1001; position:absolute; top:0; left:0; text-align:center; font-size:16px}
jQuery部分:
我们使用jQquery来完成前端动作,包括掷色子动画,仿大富翁奖品逐步运动动画,其中有防重复点击知识、ajax交互知识,动画提示知识。整个 操作流程可简单概括为:点击色子->向dice.php发送ajax请求->完成掷色子动画->提示点数->逐步运动动画到最终 奖品位置停止->完成抽奖。
复制代码 代码如下:
$(function(){
$('#dice').click(function(){
$('#prize li .mask').remove();
$('.wrap').append('
var dice1 = $('#dice1');
var dice2 = $('#dice2');
$.getJSON('dice.php',function(json){
var num1 = json[0];
var num2 = json[1];
diceroll(dice1,num1);//掷色子1动画
diceroll(dice2,num2);//掷色子2动画
var num = parseInt(num1)+parseInt(num2);
$('#msg').css('top','-10px').fadeIn(500).text(num+'点').animate({top:'-50px'},'1000').fadeOut(500);
roll(0, num);//逐步运动动画
});
});
});
函数diceroll()是一个色子运动动画,在本站前面的文章中已讲解过,就是通过jQuery的animate()实现的位移、延时、变化背景样式来实现的动画效果。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
