TreeView（扩充XMLSelTree）（一）

 

TreeView（扩充XMLSelTree）

VisualSW

基于XML、JavaScript的TreeView。

参考http://61.163.246.155/pro/XMLSelTree/感谢XMLSelTree程序的作者。

增加功能：右键添加删除节点、保存Check状态、展开所有节点、合并所有节点等。

效果图：

合并

获取XML，获取树结构的XML字符串

右键菜单操作：

实现：

TreeNode.xml结构修改为：

<?xml version='1.0' encoding='gb2312'?>

<Root>

       <TreeNode Title='测试001' CheckData="001" Checked="true">

              <TreeNode Title='目录测试001' CheckData="002" Checked="true"/>

              <TreeNode Title='测试0011' CheckData="003" Checked="true">

                     <TreeNode Title='目录测试001' CheckData="004" Checked="false"/>

                     <TreeNode Title='目录测试222' CheckData="005" Checked="true"/>

                     <TreeNode Title='目录测试333' CheckData="006" Checked="false"/>

                     <TreeNode Title='目录测试444' CheckData="007" Checked="false"/>

              </TreeNode>

              <TreeNode Title='测试0012' CheckData="008" Checked="false">

                     <TreeNode Title='目录测试001' CheckData="009" Checked="false"/>

                     <TreeNode Title='目录测试222' CheckData="010" Checked="false"/>

                     <TreeNode Title='目录测试333' CheckData="011" Checked="false"/>

                     <TreeNode Title='目录测试444' CheckData="012" Checked="false"/>

              </TreeNode>

       </TreeNode> 

</Root>

增加attribute:Checked标识是否选中。

 

下载XMLSelTree，添加下面代码。

{

    var strReplace="CHK=\"true\"";
