I try to eleminate an 404 error occuring because the source (src) is missing..
var $chart = $(\"
\")
.addClass(\"trend-pic\")
.error(func
You can't really delete those 404 errors from the console. The best you can do is make some ajax calls and see the return code, but then you'll be limited to request only to your own domain.
EDIT--
Oh, and yes, those errors will keep showing in the "Requests" tab! They just won't appear in the "Console" tab (in Chrome).
