js调试问题

比如说：第一个html页面是<head>
    <title>Index</title>
</head>
<body>
    <div>
        <input  id='mybtn' type="button" value='clcik' />
    </div>    <div id='contentDIV'></div>
    <script src="../../Scripts/jquery-1.5.1.js" type="text/javascript"></script>
    <script type="text/javascript">        $(document).ready(function () {            $("#mybtn").click(function () {                $.ajax({
                    type: "POST",
                    url: "/Home/ContentView",
                    data: "传到后台的东西",
                    dateType: "html",
                    success: function (responseData) {                        $("#contentDIV").html(responseData);
                    }
                });            })//end click
        
        })//end document.ready    </script></body>第二个html页面是<p>
    click me:
    <input  id='i2' type="button" value='other page'/>
</p>
<script src="../../Scripts/jquery-1.5.1.js" type="text/javascript"></script>
<script type="text/javascript">    $(document).ready(function () {        $("#i2").click(function () {
            var a = 1;
            var b = "bbbbb";            alert("page 2");
        })
    
    
    })//end  document.ready</script>
页面一的button调用了页面2
怎么在页面2中打断点调试js
