Afternoon,
The following snippet from cas.js in CAS 3.5.2 (and 4.0 RC1)
triggers/displays an error (pop-up) in some browsers (saw this morning
in IE 8) which, in effect, says "window.console" is null:
> if (!window.console || window.console == {}) {
> window.console.log = function() {};
> }
I don't know offhand what this intends to do, though guess it either
tries to 'step on' (disable) console logging by setting to an empty
function, or ensure window.console.log is a resolvable, albeit empty,
function when not defined.
I also see that older versions of IE (!) will throw errors if
console.log is referenced and developer tools are not currently open
(*). The offered workaround is:
if(!window.console){ window.console = {log: function(){} }; }
a little different than the above snippet.
Thanks for any advice.
Tom.
