right, i get you....thanks for the advice.
@liammclennan - when you say the arg to appendChild is not a JQ wrapper, you mean the jq eval returns a dom element and not a jq object? if so why does console.log($('<input>')) display [<input>] instead of <input>?
Sorry. My previous comment was nonsensical.
What I meant was that appendChild is a dom function, not a jquery function, so the argument should be a dom element. Your original code was passing it a jquery wrapper, which I think is an error. I suggested .get(0) as a way to extract the actual dom element, which would make it work. Alternatively, and probably preferably, you can use get a jquery wrapper for the row ($(this)) and then use one of the jquery functions (append, prepend, etc).
yep. thats the updated version (see above) from OJ.
Out of curiosity - any reason why its preferable that way?
yeah makes sense - thanks :)
I agree it should be
eachovermap. You're essentially doing anActionnot aFunc<T>:)
