So today I was creating a checkbox element in jQuery when I noticed
that I had a typo in my code.. I had declared the initial tags as:
var checkbox = $('<input></input');
Totally forgetting to append the last '>' symbol at the end of the
closing tag. I was surprised to find that this hadn't thrown some
kind of error or hadn't caused unwanted behavior in my checkbox when
the page was rendered. when I corrected the problem though, something
really odd happened. I ended up with the error below in Firebug and
the whole page crashed:
[Exception... "'type property can't be changed' when calling method:
[nsIDOMEventListener::handleEvent]" nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)" location: "<unknown>" data: no] in
jquery.js line 2869
Seems that attempting to change the attributes on the new object was
failing now that the correct syntax was in place. When I replaced the
typo by removing the '>' sign, the error went away and everything was
fine again. I did some investigation and found the following worked
fine as well:
var checkbox = $('<input>');
$(checkbox).attr('type', 'checkbox');
and
var checkbox = $('<input/>');
$(checkbox).attr('type', 'checkbox');
The only time the problem shows up, is when I use the tag declaration $
('<input></input>');
