Expending Node Client side

[Igor]

I'm using JavaScript to expand a tree node based on the condition. Script work in IE and FF but not in Chrome, the version of my Chrome browser is 11.

function ClientNodeExpanded(sender, eventArgs) {

    var node = eventArgs.get_node();

 

    if (typeof (node) !== 'undefined' && node != null) {

        if (node.get_nodes().get_count() > 0) {

            for (var i = 0; i <= node.get_nodes().get_count(); i++) {

                var ChildNode = node.get_nodes().getNode(i);

                if (typeof (ChildNode) !== 'undefined' && ChildNode != null) {

                    if (ChildNode.get_text() == "Online") {

                        ChildNode.expand(true);

                    }

                }

            }

        }

    }

}

Can you tell me if this is a problem with the control or i'm doing something wrong?

Thanks you.

Hello Igor,

The snippet looks fine, so we'll need a sample project with the menu and snippet included.

I found the problem, in Chrome for some reason the ChildNode.get_text() is returning an empty string.
So i had to do a work around just for chrome browser. Here is my updated function.

function ClientNodeExpanded(sender, eventArgs) {
    var node = eventArgs.get_node();

    if (typeof (node) !== 'undefined' && node != null) {
        if (node.get_nodes().get_count() > 0) {
            for (var i = 0; i <= node.get_nodes().get_count(); i++) {
                var ChildNode = node.get_nodes().getNode(i);
                if (typeof (ChildNode) !== 'undefined' && ChildNode != null) {
                    var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
                    if (is_chrome) {
                        if (ChildNode.get_textElement().textContent == "Online") {
                            ChildNode.expand(true);
                        }
                    }
                    else {
                        if (ChildNode.get_text() == "Online") {
                            ChildNode.expand(true);
                        }
                    }
                }
            }
        }
    }
}
