Suppose we want to remove all children of the node 
node:
while(node.firstChild) {
node.removeChild(node.firstChild);
}
That’s all there is to it

Hi, I am trying to remove the nodes like in your example and than add them again. Firstly I have a memory leak after that, and also sometimes i have an awfull “this.target is null
error source line: [Break on this error] Ext.ToolTip=Ext.extend(Ext.Tip,{showDe…ithin(this.target.dom,true)){return;}” error );
Just to bring to ppls attention, there’s a new removeAll method on the tree node. Looks like its only in version 3.2 and not 3.1 (worked that out the hard way). removeChild also doesn’t work in 3.1 but fixed in 3.2.
This works, thanks. Love your site!
Very interesting and informative site! Good job done by you guys, Thanks
while(node.firstChild && node.firstChild.remove());
Awesome, really helped me, thanks!
Nice! I was looking for this, thanks.
