  • Events not working as expected #63235


    I am new’ish to jqxTree. In my example, I expect that when I click the checkbox I will see an alert (see the code), also when I uncheck the checkbox. But I don’t get the alerts. Am I doing something wrong? If I run firebug it says too much recursion (but it still won’t work if disabled), in IE, I get a stack overflow. I am running jQWidgets v3.5.0 (2014-Sep-15)

    Hi mshaw,

    I don’t suggest you to check an item whithin a “checkChange” event handler because that will lead to recursion – you will check an item with code and the event will be raised again.

    Here’s a link to a working sample which illustrates how to handle this event: http://jsfiddle.net/g2syu09x/
