tree.setImagePath("Images/");
tree.enableCheckBoxes(1);

//可动态进行改变树级目录
tree.loadXML("XmlFile/mainMenuTree.xml");
</script>
<br><br>
<p><a href="javascript:self.close()">Close this page</a></p>

<script type="text/javascript" language="javascript">
<!--
function catchValue()
{
    var valueData=tree.getSelectedItemText();
    alert(valueData); 
    var checked=tree.getAllChecked();
   
    /*******************************问题处*******************************************
    在这里怎样才能把checked这个字符串中以逗号为分割的字符进行拆解，或者说是怎样可以
    直接得到各个根接点以及根接点下字节点的值，比如说用循环的方式来处理。在这里应该怎样写啦！
    我看他的开发文档中好象不支持去取单个接点的值啦！！我用的是他的标准版！！！
    *********************************************************************************/
    alert(checked);
}
//全部展开或者全部收缩
//-->
</script>

望熟悉使用过这个控件的Jser帮个忙啦！！
在下感激溜涕啦！！！

我没听清楚你要干什么 但是API明明就有你要的方法
单个得到子节点的ID 或者根据checked节点ID 得到下所有子节点ID
或者根据checked节点ID 得到有多少子节点 
getChildItemIdByIndex(itemId,index)
retun child node id by index

getSubItems(itemId)
Returns the list of all children items from the next level of tree, separated by commas.

hasChildren(itemId)
return number of childrens
