js编写的treeview使用方法

本文实例为大家分享了treeview使用方法，供大家参考，具体内容如下

1.所需文件：ftiens4.js,ua.js,XMLTree.js,以及一些树上的图片（文件下载处：http://www.treeview.net/），图片名字和位置如下图

2.其他页面（MainContent.aspx,NavTree.aspx）放置位置如下图所示:

3.关键页面的代码

3.1 MainContent.aspx代码

<%@ Page Language="C#" CodeFile="MainContent.aspx.cs" Inherits="mainContent" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
  <title>北京市城市轨道交通设施运行状态监测系统</title>
  <link rel="Shortcut Icon" href="Resources/Images/iehead.ico" />
  <link rel="Bookmark" href="Resources/Images/iehead.ico" />
  <script type="text/javascript">
  function op()
  {
   // This function is for folders that do not open pages themselves.
   // See the online instructions for more information.
  }
 </script>
</head>
 <frameset cols="250,10,*" border="0" frameSpacing="0" frameBorder="no" id="tree_frm">
   <frame src="navTree.Aspx" name="treeframe" noResize>
   <frame src="treeControl.htm" name="ctr_frm" id="ctr_frm" noResize scrolling="no">
   <frame src="#" name="mainGisWindow" id="basefrm" noResize>
 </frameset>
</html>

3.2 NavTree.aspx代码

<%@ Page Language="C#" CodeFile="NavTree.aspx.cs" Inherits="navTree" %>


<html >
<head runat="server">
  <title>北京市城市轨道交通设施运行状态监测系统</title>
  
<script src="Resources/JS/Tree/ua.js" type="text/javascript" language="javascript"></script>

<script src="Resources/JS/Tree/XMLTree.js" type="text/javascript" language="javascript"></script>
  <%
   //Common.Utility.WebUtility.validLoning(Session, Response);
   string fileName = null;
   //Bussiness.Login.User loginUser = (Bussiness.Login.User)Session["currentUser"];
   string departmentid = "";
   if (Session["navItem"] != null)
   {
     string item = (string)Session["navItem"];

     if (item.ToUpper().Equals("Safety".ToUpper()))
     {
       fileName = "'SafetyTree.xml'";
       //departmentid = loginUser.department.depId;
     }
     else if (item.ToUpper().Equals("Gis".ToUpper()))
     {
       fileName = "'GisTree.xml'";
     }
     else if (item.ToUpper().Equals("DataQuality".ToUpper()))
     {
       fileName = "'DataQualityTree.xml'";
     }
     else if (item.ToUpper().Equals("StateAnalysis".ToUpper()))
     {
       fileName = "'StateAnalysisTree.xml'";
     }
     else if (item.ToUpper().Equals("SynthesisTechnique".ToUpper()))
     {
       fileName = "'SynthesisTechniqueTree.xml'";
     }
     else if (item.ToUpper().Equals("DataMaintenance".ToUpper()))
     {
       fileName = "'DataMaintenanceTree.xml'";
     }
   }   
   %>
<script type="text/javascript">
  var xmlfile = "Resources/XML/Tree/"+<%=fileName %>;
  departmentid= '<%=departmentid %>';
  ICONPATH = 'Resources/Images/tree/';
  contentFrame = window.parent.document.getElementByIdx_x_x("basefrm");
  loadTreeFromXml(xmlfile);
</script>

3.3 treeControl.aspx代码（它的作用就是树和右边页面的分隔栏，可以隐藏树）

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
  <script type="text/javascript" language="javascript">
    var LEFT_MENU_VIEW=1;
    function leftmenu_ctrl()
    {
     if(LEFT_MENU_VIEW==0)
     {
      parent.tree_frm.cols="250,10,*";
      LEFT_MENU_VIEW=1;
      myarrow.src="/ESM/Resources/Images/topleft.gif"; //左箭头
     }
     else
     {
      parent.tree_frm.cols="0,10,*";
      LEFT_MENU_VIEW=0;
      myarrow.src="/ESM/Resources/Images/topright.gif"; //右箭头
     }
    }
  </script>

</head>
<body style="background-color:#F1F8FC;">
  <div id="AdLayer" style="position:absolute;width:60px; height:21px; z-index:20;visibility:visible;left:0%; top:40%;">
    <div id="oa_tree" onclick="leftmenu_ctrl();" title="隐藏工具栏" style="cursor:pointer;"><img id="myarrow" src="/ESM/Resources/Images/topleft.gif" alt="" /></div>
  </div>
</body>
</html>
