你可以做到

$(document).ready(function(){
    $(".first,.last").click(function(){
       var row = $(this).parents("tr:first");
       var rows= row.parents().find("tr");
       if ($(this).is(".first")) {
           row.insertBefore(rows[0]);
       } else {
           row.insertAfter(rows[rows.length]);
       }
   });  
});

$('#getmessage').on('click', function () {
    var text = '';
    $('#discussion>li').each(function () {
        text += $(this).text();
        text += '\n'
    })
    console.log(text)

    $.ajax({
        url: 'File/Index?data=' + text, // Just make change here..
        type: 'POST',
        data: text,
        success: function (result) {
            console.log("data send");
        }
    })
})
