     <link   rel="stylesheet" href="../demo1/bootstrap/css/bootstrap.css">

</head>
<body>
<button  id="sb"  type="button" class="btn btn-info">信息按钮</button>

<script>
 $(document).ready(function(){
        $("#sb").click(function(){
            $.post("http://localhost/demo2/test1.php",{
                        name:"印第安老斑鸠",
                        url:"http://www.laobanjiu.com"
                    },
                    function(data,status){
                        alert("数据: 
" + data + "
