Asp.Net统一前后端提示信息方案

目录

 

 

要解决的问题
  1. 减少弹框前后端代码量
  2. 增强可维护性
  3. 前后端提示资源统一
  4. 可以实现简单的多语言提示方案
  5. 增强重用性和易用性

      ...

用自定义XML汇总提示信息
  • 为了实现前后端提示资源的统一,把提示信息放入自定义XML文件中,初步想法如下(alerttip节点表提示信息节点)
<?xml version="1.0" encoding="utf-8" ?>
<tiplist> 
  <alerttip>
    <id>1</id>
    <chinese>成功</chinese>  
  </alerttip>
  <alerttip>
    <id>-1</id>
    <chinese>失败</chinese>   
  </alerttip>
</tiplist>
  • 进一步为了实现简单支持多语言版本和语言设置进一步修改XML结构,修改后如下(增加language节点控制项目语言版本,每个alerttip节点下增加其它语言提示信息)
<?xml version="1.0" encoding="utf-8" ?>
<tiplist>
  <language>
    <value>chinese</value>
  </language>
  <alerttip>
    <id>1</id>
    <chinese>成功</chinese>
    <english>success</english>
  </alerttip>
  <alerttip>
    <id>-1</id>
    <chinese>失败</chinese>
    <english>fail</english>
  </alerttip>
</tiplist>
前端弹框实现
  • Jquery解析XML文件,通过ID节点,返回对应的提示信息
function getTip(tipId) {
    var returnVal = "";
    $.ajax({
        url: 'xml/tip.xml',
        type: 'get',
        dataType: 'xml',
        timeout: 1000,
        cache: true,
        async: false,
        error: function(xml) {
            returnVal = 'Loading Error!';
        },
        success: function(xml) {
            var language = $(xml).find('language:first').children("value").text();
            $(xml).find("alerttip").each(function(i) {
                var idVal = $(this).children("id").text();
                if (idVal == tipId) {
                    returnVal = $(this).children(language).text();
                    return false;
                }
            });
        }
    });
    return returnVal;
}
  • 提取弹框提示方法
/*-------------------------------------------------------------------------------------------
功能:Windows弹框,通过传入XML文件中ID节点的text查找提示正文
参数:tipId表示XML中ID节点的text
---------------------------------------------------------------------------------------------*/
function alertXml(tipId) {
    alert(getTip(tipId));
}

/*-------------------------------------------------------------------------------------------
功能:Windows弹框,通过传入提示正文
参数:tips表示提示正文
destUrl表示要跳转的目的路径
---------------------------------------------------------------------------------------------*/
function alertGo(tips, destUrl) {
    alert(tips);
    location.href = destUrl;
}

/*-------------------------------------------------------------------------------------------
功能:Windows弹框,通过传入XML文件中ID节点的text查找提示正文
参数:tipId表示XML中ID节点的text
destUrl表示要跳转的目的页面路径
---------------------------------------------------------------------------------------------*/
function alertGoXml(tipId, destUrl) {
    alertGo(getTip(tipId), destUrl);
}
后端弹框实现
  • C#解析XML文件,存入Dictionary,并添加XML文件依赖缓存
        

         //提示信息字典
         private static Dictionary<string, string> tipDic = null;


#region## 根据ID从XML文件中获取提示信息 /// <summary> /// 根据ID从XML文件中获取提示信息 /// 进行XML文件依赖缓存 /// </summary> /// <param name="filePath">XML提示文件路径</param> /// <param name="tipId">XML文件中ID节点</param> /// <returns>提示信息</returns> private static string GetTipDic(string filePath, string tipId) { string tipStr = string.Empty; if (HttpRuntime.Cache["TipCache"] == null) { tipDic = new Dictionary<string, string>(); string xmlPath = HttpContext.Current.Server.MapPath(filePath); XDocument doc = XDocument.Load(xmlPath); var language = doc.Descendants("language").First().Element("value").Value; var tipList = doc.Descendants("alerttip"); foreach (var item in tipList) { string id = item.Element("id").Value; if (!tipDic.ContainsKey(id)) { tipDic.Add(id, item.Element(language).Value); } } CacheDependency dep = new CacheDependency(xmlPath); HttpRuntime.Cache.Insert("TipCache", tipDic, dep, System.Web.Caching.Cache.NoAbsoluteExpiration, System.Web.Caching.Cache.NoSlidingExpiration); } else { tipDic = HttpRuntime.Cache["TipCache"] as Dictionary<string, string>; } if (tipDic.ContainsKey(tipId)) { tipStr = tipDic[tipId]; } return tipStr; } #endregion
