css 借助autoflow 属性实现选座位效果

1.autoflow属性，如果元素内容的长宽超出元素本身的长宽则会出现滚动条

<HTML> <HEAD> <TITLE>测试表格内的滚动条</TITLE> </HEAD> <BODY> <div id="wins"         style="position:absolute;height:200;width:200;overflow:auto;background:#EEEEEE;">         <p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>         <p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>         <p>ppppppppppppppppppppppppp </p>       </div></BODY> </HTML>

效果如下

2.选座位页面

<html><head> <meta charset="utf-8">  <title>座位</title> <meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no"> <link rel="stylesheet" href="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/js/bootstrap.min.js"></script> <style type="text/css">      table tr td{        padding: 5px;      }     </style>      </head>   <script>  function createTable(){var DivW=600;var DivH=400;var length=30;var height=$("#h").val()/1;var width=$("#w").val()/1;var TableW=width*(length+3);var TableH=height*(length+3);$(".main").empty();$(".main").width(TableW).height(TableH);for(var a=0;a<height+1;a++){ var str="<tr>"; for(var b=0;b<width+1;b++){  if(a==0&&b>0){   str+=<td height="30px" width="30px">+b+</td>;  }  if(b==0&&a>0){     str+=<td height="30px" width="30px">+a+</td>;  }  if(b>0&&a>0){   str+=<td height="30px" width="30px" ><img src="img/2.png" width="30px" height="30px" /></td>;  }    if(a==0&&b==0){    str+=<td height="30px" width="30px"></td>;  } } str+="</tr>"; $(".main").append(str);}  }   </script><body><!-- 按钮触发模态框 --><button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal" onclick="createTable()"> 座位</button><input type="text" id="h" />排<input type="text" id="w" />座<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-dialog">        <div class="modal-content">   <div id="wins" style="position:absolute;height:400;width:600;overflow:auto;background:#ffffff;">     <table class="main" style="text-align:center;">       </table>   </div>  </div> </div></div></body></html>
