通用調查系統開發

      調查系統是一個變化非常頻繁的系統，無論界面還是調查內容每個調查都大不相同，要想做出一個擴展性強、能應對所有調查系統非常不易，在做了許多調查的程序後，我設計了這個調查系統，

首先：爲了應對調查內容的變化，在數據庫設計的時候不爲調查的每一項設計字段，而是把整個調查頁面的html代碼保存在一個字段裏，

其次：爲了應對調查界面上的變化，美工把調查頁面設計好以後，我把放在web編輯器裏提交到數據庫裏，填寫調查的時候，用asp.net程序地址欄的suivryid參數從數據庫裏把相應的調查內容讀出來，賦給一個label標籤。每個調查用到的樣式表都不一樣，爲了能讓每個調查調用到自己的樣式，我寫了一個xml文檔 。象下面那樣：

<?xml version="1.0" encoding="gb2312"?>
<root>
<cssnode>
<css sureyid="105" sureycss="/css/main.css"/>
<css sureyid="106" sureycss="/css/spc.css"/>
<css sureyid="108" sureycss="/css/eworkshd.css"/>
<css sureyid="110" sureycss="/css/ge.css"/>
<css sureyid="112" sureycss="/css/sap.css"/>
<css sureyid="114" sureycss="/css/style_sap.css"/>
<css sureyid="115" sureycss="/css/scm.css"/>
<css sureyid="117" sureycss="/css/eworkssurvey.css"/>
<css sureyid="119" sureycss="/css/oracle.css"/>

</cssnode>
</root>

 

其中的sureyid表示調查id，sureycss表示這個調查用到樣式表。在調查頁面上放一個literal標籤，在頁面加載的時候，根據調查id，獲取xml文檔中的sureycss屬性值賦給literal， 如下所示：literal1.Text = "<link href=\"" + GetConfigStr(surveyid, "xml/surveycss.xml", "cssnode") + "\" rel=\"stylesheet\" type=\"text/css\">";

GetConfigStr方法：

  public string GetConfigStr(string type, string xmlFile, string rootnode)
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(System.Web.HttpContext.Current.Server.MapPath(xmlFile));

            XmlNodeList topM = xmlDoc.DocumentElement.ChildNodes;
            foreach (XmlElement element in topM)
            {
                if (element.Name.ToLower() == rootnode)
                {
                    //得到該節點的子節點集
                    XmlNodeList nodelist = element.ChildNodes;

                    if (nodelist.Count > 0)
                    {
                        foreach (XmlElement el in nodelist)//讀元素值
                        {
                            if (el.Attributes["sureyid"].Value == type)
                            {
                                return el.Attributes["sureycss"].Value;
                            }

                        }

                    }
                }
            }
            return "";

        }

 每個調查提交的時候都需要用js做一些必填項、安全性驗證，而且每個調查的驗證都不一樣，爲了能應對這個問題，首先我把一通用的js提取出來放在一個js文件裏，

然後針對每個不同的調查分別寫驗證的js,然後象上面調用樣式表那樣用一個xml文檔記錄每個調查對應的js文件，如下所示：

 <?xml version="1.0" encoding="gb2312"?>
<root>
<cssnode>
<css sureyid="105" sureyjs="/js/sap2013.js"/>
<css sureyid="106" sureyjs="/js/surveysave.js"/>
</cssnode>
</root>

 在調查頁面上放一個literal標籤，在頁面加載的時候，根據調查id，獲取xml文檔中的sureyjs屬性值賦給literal， 如下所示： jssrc.Text = "<script src=\"" + im.GetConfigStr("105", "xml/jssrc.xml", "cssnode") + "\" type=\"text/javascript\"></script>";

有人會問：你把所有調查內容保存在一個字段裏做調查的時候是簡單輕鬆快捷了，但要得到調查結果就讓人頭疼了，爲了解決這個問題我做了一個通用的調查結果分析程序用來分析、提取客戶提交的html代碼的類，這個類代碼大致如下：
