Q:

jquery splitter change to vertical splitter on button click

I have a splitter that works fine. Now the client wants to change the splitter from horizontal view to vertival view. I mean that the splitter is first split int the 2 divs horizontally and when I click the button it will change so that it's split the same 2 divs vertically.
I tried this
     <script type="text/javascript">
        $(function () {
        $('.LeftPane').attr('id', 'LeftPane');
        $('.RightPane').attr('id'`enter code here`, 'RightPane');
        $("#MySplitter").splitter({
            type: "v"
        });
        $('#Button1').click(function () {
            $('#LeftPane').attr('id', 'TopPane');
            $('#RightPane').attr('id', 'BottomPane');
            $("#MySplitter").splitter({
                type: "h"
            });
        });
    });
    </script>

<style type="text/css" media="all">
   #MySplitter
    {
        height: 400px;
        width: 600px;
        margin: 1em 2em;
        background: #def;
        border: 2px solid #039; /* No padding allowed */
    }
   #LeftPane
    {
        background: #def;
        overflow: auto;
        width: 200px; /* optional, initial splitbar position */
        min-width: 50px; 
    }

    #RightPane
    {
        background: #def;
        overflow: auto;
        min-width: 100px; /* No margin or border allowed */
    }

   #MySplitter .vsplitbar
    {
        width:8px;
        cursor: e-resize; /* in case col-resize isn't supported */
        cursor: col-resize;
        background-color:Black;
    }
    #MySplitter .vsplitbar.active, #MySplitter .vsplitbar:hover
    {
         background-color:Black;
    }

     #TopPane
    {
       background: #def;
        overflow: auto;
        width: 200px; 
        min-width: 50px; /
    }

    #BottomPane
    {
       background: #def;
        overflow: auto;
        min-width: 100px; /* No margin or border allowed */
    }

     #MySplitter .hsplitbar
    {
        height: 2px;
        background: #487BA4;
    }
    #MySplitter .hsplitbar.active, #MySplitter .hsplitbar:hover
    {
        background: #487BA4;
    }
</style>

</head>
<body>
<div id="MySplitter">
    <div class="LeftPane">
        <p>
            This is the left side of the vertical splitter.</p>
        </p>
    </div>
    <div class="RightPane">
         This is the right side of the vertical splitter.</p>
    </div>
</div>
<p>
    <input id="Button1" type="button" value="splitchange" /></p>
</body>
</html>

A:

at last i find the solution of my onw question.
I am designing it in asp.net so i am providing the solution in jquery with asp.net

     $(document).ready(function () {
         // var result = function () {
        // alert('fired');

             });
         }
         // }
     });
</script>

</head>
<body>
 <form runat="server" >
<asp:HiddenField ID="HiddenField1" runat="server"  Value="1"/>
<asp:Button ID="Button1" runat="server" Text="change" OnClick="Button1_Click" />

 <div id="MySplitter">
    <div class="LeftPane">
        <p>
            This is the left side of the vertical splitter.</p>
        <p>
            Note what happens when you move the splitbar as far left as you can to make this
            pane very thin. A scrollbar appears and it is flush against the splitbar, just the
            way it should be.</p>
    </div>
    <div class="RightPane">
        <p>
            The splitbar needs to be wide enough to grab with the mouse, but a thick splitbar
            may be visually distracting in a design. This example shows how to make a splitbar
            that looks skinny but has a wider grabbing area. It also demonstrates the use of
            an alternate resize cursor. (Not all browsers support alternate cursors and only
            IE seems to support animated cursors.)</p>
        <p>
            A background image in the splitbar provides the visual marker but the splitbar area
            extends further right, appearing as padding on the right pane. The splitbar's hot
            zone is "biased" to the right so that it will not have a gap against any left-side
            scrollbar when it appears. If you know the left pane will never have a scroll bar,
            you could make the hot zone centered on the skinny splitbar.</p>
    </div>
</div>
</form>

Code behind for button is as follows
 protected void Page_Load(object sender, EventArgs e)
    {
        if (HiddenField1.Value == "2")
        {
            HiddenField1.Value = "1";
        }
        else
        {
            HiddenField1.Value = "2";
        }
    }
