javascript 读取XML数据，在页面中展现、编辑、保存的实现

网络编程 2024/11/16 佚名

3 2 1

首先考虑用什么方法做，考虑到三个方式：1、C#拼HTML构造table，修改和保存通过Ajax实现。2、XML+XSL，展现和修改用两个XSL文件来做，Ajax修改、保存XML。3、GridView控件。
经过细致考虑，首先第三方案GridView控件满足不了需求，因为XML格式多样，可能涉及到很多的行、列合并和行、列表头合并。第一方案太麻烦，坐起来是细致活和体力活，需求变动后不好修改。所以选择第二方案。开始学习XPath、XSLT。AJAX用js异步调用一般处理文件(ashx)的方式。
1、实现选择框（通过Ajax读取数据库，绑定数据）的绑定时出现错误，最终发现是在读取XML时使用了异步方式与Ajax有冲突，用同步就可以解决了。
2、保存XML。修改后的数据怎么保存到XML了？通过Javascript保存，js不能保存，如果用js保存必须用hta；用AJax保存，怎么能让修改后的XML传到AJAX方法里去，瞎琢磨，试了几种方法，还真让我试出来了，源码
js：
复制代码代码如下:
var $=function (id){return document.getElementById(id);}
var xmlHttp;
var curControl;
var curValue;
function ToEdit(){
var xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.load("myxml.xml");
var xsl = new ActiveXObject("Microsoft.XMLDOM");
xsl.async = false;
xsl.load("myxsl_edit.xsl");
document.write(xml.transformNode(xsl));
document.close();
//绑定选择框
LoadSelect();
}
//保存xml
function Save(){
var oDoc = new ActiveXObject("MSXML2.DOMDocument.3.0");//负责得到响应结果
oDoc.async = false;
oDoc.resolveExternals = false;
oDoc.load("myxml.xml");
var data = oDoc.selectNodes("//Data[@IsEdit='1']");//读取所有请求大类所属小类的类名
for(var i=0; i < data.length; i++)
{
var nodeEdit;
var nodeID;
var nodeType;
for(var j=0; j<data[i].attributes.length; j++)
{
if(data[i].attributes[j].nodeName=="IsEdit")
{
nodeEdit = data[i].attributes[j].nodeValue;
}

ajax实现得到数据集的ashx代码
复制代码代码如下:
<%@ WebHandler Language="C#" Class="getDataSet" %>
using System;
using System.Web;
using System.Data;
using System.Data.SqlClient;
using System.Text;
using DHCC.HISHR.BO;
public class getDataSet : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string result = "";
string table = context.Request.Params["table"].ToString().Trim();
string value = context.Request.Params["value"].ToString().Trim();
string text = context.Request.Params["text"].ToString().Trim();
string sql = "SELECT " + value + "," + text + " FROM HISHR." + table + " ";
BOSQLExecuter SQLexec = new BOSQLExecuter();
DataSet ds = SQLexec.GetDataSetSQLExecuter(sql);
if (ds != null)
if (ds.Tables.Count > 0)
{
DataTable dt = ds.Tables[0];
foreach (DataRow dr in dt.Rows)
{
result += "$" + dr[value].ToString() + "^" + dr[text].ToString();
}
if (result.Length > 0)
result = result.Substring(1);
}
//根据ＨＴＴＰ局部请求返回流到页面
context.Response.Write(result);
}
public bool IsReusable
{
get
{
return false;
}
}
}

ajax保存XML的ashx代码
复制代码代码如下:
<%@ WebHandler Language="C#" Class="saveXML" %>
using System;
using System.Web;
using System.Xml;
using System.IO;
public class saveXML : IHttpHandler
{
public string xml;
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string path = System.Web.HttpContext.Current.Request.PhysicalApplicationPath;
string strXML =context.Request.Form[0];
try
{
if (File.Exists(path + "\\myxml.xml"))
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(strXML);
xmldoc.Save(path + "\\myxml.xml");
context.Response.Write("true");
}
}
catch
{
context.Response.Write("false");
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
