一个简单的投票功能

html代码：

<html>
 <head>
 </head>
 <body>
 <h3 id='toupiao'>请选择</h3>
<div id="div">
 1:<input type="radio" name="vote" value="0" onclick="getpiao(this.value)"><br>
 2:<input type="radio" name="vote" value="1" onclick="getpiao(this.value)"></div>
 <table style='display:none' id="table">
 <tr>
 <td>选1:</td>
 <td>
    <input style=" height:20px;background-color:red" value="" id="yes"/>%
 </td>
 </tr>
 <tr>
 <td>选2:</td>
 <td>
    <input style=" height:20px;background-color:blue" value="" id="no">%
 </td>
 </tr>
 </table>
 <script type="text/javascript" src="jquery-1.8.1.min.js"></script>
 <script>
 function getpiao(int)
 {
    $.post("/toupiao/piao.php",{"piao":int},function(data){
            if(data.yes!="" || data.no!=""){
                var newno = parseInt(data.no);
                var newyes = parseInt(data.yes);
                $('#yes').val((newyes/(newno+newyes)*100).toFixed(2));
                $('#yes').css('width', (newyes/(newno+newyes)*100).toFixed(2)+'px');
                $('#no').val((newno/(newno+newyes)*100).toFixed(2));
                $('#no').css('width', (newno/(newno+newyes)*100).toFixed(2)+'px');
                $('#table').css('display',"block");
                $('#div').css('display',"none");
                $('#toupiao').html('投票结果');
            }
    },"json");
 }
 </script>
 </body>
 </html>

PHP代码：

<?php
 $piao = $_POST['piao'];
 $filename = "piao.txt";
 $content = file($filename);
 $array = explode("/", $content[0]);
 $yes = $array[0];
 $no = @$array[1];
 if ($piao == 0)
    $yes = $yes + 1;
 if ($piao == 1)
    $no = $no + 1;
 $insertpiao = $yes."/".$no;
 $fp = fopen($filename,"w");
 fputs($fp,$insertpiao);
 fclose($fp);
 echo json_encode(array('yes'=>$yes,'no'=>$no));
 ?>
