How to write a javascript function to exapand/collapse all nodes in a TreeMenu

[Keerthi Chandhu]

Hi,

I am trying to write a javascript function to collapse/expand all nodes in a tree menu.
Could anyone please give me some idea how to write this function?

Thank you.

Where's your code?

Agree with Bear,

It depends on your implementation.

if you need a starting place:

onclick

obj.style.display="none"

Hi,

Please find my code.

function collapseAll(){
for(var i=0;i<node.length;i++){
	if( tree.Expanded){
		tree.Expanded=false;
	}
    }
}
<input class="button" type="button" name="collapseALL" value="CollapseALL" onclick="collapseAll()" />

I am trying to write a function like
If user clicks a collapse all button it should collapse entire tree view nodes.
I do not understand how to check the condition to find whether a tree is expanded or not. if( tree.Expanded){

Any suggestions would be appreciated.


Thank you.

And what is the tree that you are using? There are 1000's of them out there.
