远远地眺望，草地上有团团白云在蠕动，原来这是牧场的羊群，一只只白生生的，肥壮可爱，使草原更加生的小鸟儿唧唧喳机勃勃。
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" %>

<script type="text/javascript">
function op()
{
// This function is for folders that do not open pages themselves.

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）

myarrow.src="/ESM/Resources/Images/topleft.gif"; //左箭头

这样就成了。
本文js编写的treeview使用方法到此结束。如果爱里没有责任，爱就变得自私。如果爱里没有节制，爱就容易放纵。如果爱里没有平等，爱就变成一种施舍。如果爱里没有尊重，爱就变成一种专制。如果爱里没有喜乐，爱就不能成为真爱。如果爱不能光明正大，爱就是罪恶的化身。小编再次感谢大家对我们的支持！
