PHP+jQuery develops the function of simple card flop lottery (code example)

PHP jQuery develops a simple example of flip card lottery. The implementation process is as follows: 6 squares are placed on the page as prizes. When the lottery winner clicks on a certain square, the square flips to the back to display the winning information. This prize is random and not fixed.

Place 6 awards on the page:

<ul id="prize"> 
    <li class="red" title="点击抽奖">1</li> 
    <li class="green" title="点击抽奖">2</li> 
    <li class="blue" title="点击抽奖">3</li> 
    <li class="purple" title="点击抽奖">4</li> 
    <li class="olive" title="点击抽奖">5</li> 
    <li class="brown" title="点击抽奖">6</li> 
</ul>

Click each square, the event triggered:

$("#prize li").each(function() { 
    var p = $(this); 
    var c = $(this).attr('class'); 
    p.css("background-color", c); 
    p.click(function() { 
        $("#prize li").unbind('click'); //连续翻动 
        $.getJSON("ajax.php", 
        function(json) { 
            var prize = json.yes; //抽中的奖项  
            p.flip({ 
                direction: 'rl', 
                //翻动的方向rl：right to left  
                content: prize, 
                //翻转后显示的内容即奖品  
                color: c, 
                //背景色  
                onEnd: function() { //翻转结束  
                    p.css({ 
                        "font-size": "22px", 
                        "line-height": "100px" 
                    }); 
                    p.attr("id", "r"); //标记中奖方块的id  
                    $("#viewother").show(); //显示查看其他按钮  
                    $("#prize li").unbind('click').css("cursor", "default").removeAttr("title"); 
                } 
            }); 
            $("#data").data("nolist", json.no); //保存未中奖信息  
        }); 
    }); 
});

Turn over other squares :

$("#viewother").click(function() { 
    var mydata = $("#data").data("nolist"); //获取数据  
    var mydata2 = eval(mydata); //通过eval()函数可以将JSON转换成数组  
    $("#prize li").not($('#r')[0]).each(function(index) { 
        var pr = $(this); 
        pr.flip({ 
            direction: 'bt', 
            color: 'lightgrey', 
            content: mydata2[index], 
            //奖品信息（未抽中）  
            onEnd: function() { 
                pr.css({ 
                    "font-size": "22px", 
                    "line-height": "100px", 
                    "color": "#333" 
                }); 
                $("#viewother").hide(); 
            } 
        }); 
    }); 
    $("#data").removeData("nolist"); 
});
