What the heck is..
uncaught exception: [Exception… “Could not convert JavaScript argument arg 0 [nsIDOMHTMLDivElement.appendChild]” nsresult: “0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)” location: “JS frame :: PATH_TO_MY_JAVASCRIPT_FILE :: THE_METHOD_NAME :: line #” data: no]
For me it was just an appendChild() that was causing the problems. You can always try the innerHTML+= way if all else fails 😉
got this too, but after I looked more carefully I noticed the problem. the code was:
var a = document.createElement(“a”);
a.appendChild(‘hello world’);
…
someDiv.appendChild(a);
Problem is at line 2. The correct way is:
a.appendChild(document.createTextNode(‘hello world’));
Thanks for your comment on this issue!
As you have noticed a string is not a valid DOM element and should rather be used within an actual element like the TextNode you instantiated it on.
same ! FFS
