Question

以下代码用于从数据库中获取特定用户数据 并显示在Readable Textbox's 我有另一套Textbox's用于insert data into database，在插入数据后我想获取该数据并显示在Readable Textbox到txtuser Textbox。

// this jquery code execute when we click on `Get Button`

        $('#btnGet').click(function(){
          var txtuser = $('#txtuser').val();
          $.ajax({
          contentType: 'application/json; charset=utf-8',
                        url: 'WebForm1.aspx/GetUser',
                        data: JSON.stringify({ username: txtuser}),
                        dataType: 'json',
                        method: 'post',
                        success: function (data) {                                                            $('#txtfirstname').val(data.d.Firstname);
                            $('#txtlastname').val(data.d.Lastname);
                            $('#txtemail').val(data.d.Email);
                        },
                        error: function (result) {
                            alert('Error');
                        }
        });
    return false;
        });

 // this jquery code execute when we click on `Submit Button`

            $('#btnSubmit').click(function(){
              var txtuser = $('#txtuser').val();

                                $('#txtlastname').val(data.d.Lastname);
                                $('#txtemail').val(data.d.Email);
                            },
                            error: function (result) {
                                alert('Error');
                            }
