[Solved] Check only one node

[Jaymie]

I have this code:

function onChecked(e) {
    var treeView = $("#TreeView").data("tTreeView");
    var childNodes = $('#TreeView').find("li").find('> div > .t-checkbox :checkbox')

    childNodes.each(function (index, element) {
        treeView.nodeCheck(element, false);
    });
}

What it is supposed to do is to uncheck all items and just keep the one I selected (i.e. only have one node selected at any time.
It appears to work in IE, but in firefox it doesn't seem to fire (I have added an alert at the beginning of the function for testing and that is not getting hit).

Any help would be appreciated.

Hi Jaymie,

Your fucntion works correctly on my side. Please check for JS errors.

However, the provided code can undergo a couple of improvements and optimization. For example, you can execute the handler only if the user is currently checking a checkbox (e.checked == true) and do nothing while unchecking. Also, you can iterate only through the checked checkboxes (:checked jQuery selector), not all of them.
