Expand TreeNode till certain Depth

[pramodkhare]

Hi,
This is the code to expand the treenode to certain depth, i have written 2 functions, in which one function gets recursively called till it completes expansion of given node till its given depth or till its leaf node

//This Function recurses through everynode till conditions are met
//Currently Depth is hard-coded to 4 but can be given a variable value to change as per situation
myfunction = function(Mynode){ 
if(Mynode.hasChildNodes() == false || Mynode.getDepth() >= 4){ 
        return; 
}else if(Mynode.hasChildNodes()){ 
                Mynode.expand(false); 
                Mynode.eachChild(myfunction); 
} 
} 


//this Function expands given node till depth given
//As of now the depth is given 4 but can be changed as per requirement
expandNodeTillDepth = function(treePanelId ,nodeId){
    var PNode = Ext.getCmp(treePanelId).getNodeById(nodeId);
    PNode.collapse(true);
    PNode.expand(false);
    PNode.eachChild(
    myfunction
    ); 
}

//Example Use -
//expandNodeTillDepth('myTree','ynode-18',4)

/**
  * Following Function recurses through all nodes under the given node,
  * and return an Array of AsyncTreeNode objects (containing itself)
  * (Note - If the given Object is not desired in returned array can be easily
  *  removed, using splice/slice methods of JS Array methods)
  */


  getDeepAllChildNodes = function(node){ 
        var allNodes = new Array(); 
        if(!Ext.value(node,false)){ 
                return []; 
        } 
        
        if(!node.hasChildNodes()){ 
                return node; 
        }else{ 
                allNodes.push(node); 
                node.eachChild(function(Mynode){allNodes = allNodes.concat(getDeepAllChildNodes(Mynode));});         
        } 
        return allNodes; 
}


//How To Use - 
//Consider I have a AsyncTreeNode/TreeNode - and want to get All its child nodes Array then


  var allChildNodes = getDeepAllChildNodes(Node);
  //OR
  var allChildNodes = getDeepAllChildNodes(Ext.getCmp(treePanelId).getNodeById(nodeId));
  //OR to get All nodes in a Tree
  var allChildNodes = getDeepAllChildNodes(Ext.getCmp(treePanelId).getRootNode());
