Great, Bill. I replaced `ev_roll_click` with `ev_body_load` and I now have my canvas. How encouraging!!
I still would like to know how supply the code mentioned below regarding ajax.googleapis without altering utilh.ijs. Can it be added as plain old html in the HBS noun somehow? *******Below is a quote from earlier in this thread****** Also, you may recall that I added the following lines to utilh.ijs in the <head> element. I am wondering if that is necessary, or does JHS already access similar content? <script type="text/javascript" src=" http://ajax.googleapis.com/ajax/libs/jquery$ <script type="text/javascipt"> $(document).ready(function() { }); </script> On Sat, Sep 14, 2013 at 8:27 AM, Brian Schott <[email protected]>wrote: > Bill, > > Thanks. > > I tried your test code and was encouraged by a short delay, but only the > text `hello world` appears, still.
