Question

How to get ClientID of a TreeNode in a TreeView based on one of its rendered attributes, for example, its title attribute (In my case it’s unique) ,using either Server-Side or Client-Side code?

I go with this code, but it doesn’t work, any suggestion?

    // Retrieves TreeNode ClientID.     function GetTreeNodeID(nodeTitle)     {                                     var treeNodes = document.getElementById('tvMenu').childNodes;         var treeLinks;          for(var i=0 ; i<treeNodes.length ; i++)         {                                                             treeLinks = treeNodes[i].getElementsByTagName('a');                                     for(var j=0 ; j<treeLinks.length ; j++)             {                                                         if(nodeTitle == treeLinks[j].title && treeLinks[j].title != '');                 {                                             alert('Par: ' + nodeTitle);                     alert('Title: ' + treeLinks[j].title);                     return treeLinks[j].id;                 }             }         }     }

The above code that is mentioned with the question always returns the id of root node, any suggestion?

Answer 1

innerText or innerHtml or textContent ? Wich browser do you use ?

  function GetTreeNodeID(nodeInnerText)         {                                         var tree = document.getElementById('tvMenu');             var treeLinks =  tree.getElementsByTagName('A');                  for(var element in treeLinks )             {                                                               if((nodeInnerText == treeLinks[element].innerText) && (treeLinks[element].innerText != ''))                     {                                                 alert('Par: ' + nodeInnerText);                         alert('innerText: ' + treeLinks[element].title);                         return treeLinks[element].id;                     }              }         }
