请教你曾经问过并自己解决的一个问题:"javascript实现点击treeview某一树节点的文字部分展开下级节点"

http://wenwen.zzzyk.com/z/q157816458.htm请问这个问题是怎么解决的?能告诉我代码?谢谢

追问：js部分写在相应页面就可以吗?
我没有用c#,只有PHP的


ps:你速度真块

答案：js:
 
function TreeviewExpandForSelectNode(treeViewId, expandAll, SelectNodeText) 
{ 
    var displayState = (expandAll == true ? "none" : "block");
    var treeView = $(treeViewId);
    if (treeView) 
    {
        var treeLinks = treeView.getElementsByTagName("a");
        var nodeCount = treeLinks.length;
        for (i = 0; i < nodeCount; i++) 
        {     
            if (treeLinks[i].firstChild.tagName) 
            {
                if (treeLinks[i].firstChild.tagName.toLowerCase() == "img") 
                {
                   var currentToggleLink = treeLinks[i]; 
                   var childContainer = GetParentByTagName("table", 
currentToggleLink).nextSibling;
                   //alert(SelectNodeText+"-"++"-"+treeLinks[i].firstChild.alt.length);
                   if (treeLinks[i].firstChild.alt.substring(3,treeLinks[i].firstChild.alt.length) == SelectNodeText&&childContainer.style.display == displayState) 
                   {
                        eval(currentToggleLink.href); 
                   }
                }
            }
        }
    }
} 
function GetParentByTagName(parentTagName, childElementObj) 
{ 
     var parent = childElementObj.parentNode; 
     while(parent.tagName.toLowerCase() != parentTagName.toLowerCase()) 
     { 
         parent = parent.parentNode; 
     } 
     return parent; 
}
 
c#后台调用
 
protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
      ......
      ScriptManager.RegisterStartupScript(this, typeof(Page), "ExpandTreeNode", "TreeviewExpandForSelectNode('" + TreeView1.ClientID + "' ,true,'" + TreeView1.SelectedNode.Text + "');", true);
}

上一个：请大家帮我详细解释一下javaScript问题，改程序是怎么运行的，要详细的。问题如下：
下一个：javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 javascript:documen
