Re: [Gnoga-list] problem deleting row of table
I don't really know a lot about how the DOM works, so I'll just ask:
Does this mean if we are manually deleting items and recreating them that
the DOM is ever growing (similar to a memory leak)? Since Gnoga doesn't
provide customizable dialogs yet for Singleton, I have been hacking this by
deleting and recreating views attached to another container view. Is the
inflating the DOM with abandoned entries?

I added a trace to the library code that sends scripts to the browser
and I see scripts like: delete gnoga['row_xyz']; being sent. In the
console of a debugger I can see that gnoga['row_xyz'] will return null
after the delete but the row is not removed from the DOM.
If I execute $('#row_xyz').remove() in the debugger console the row is
removed from the DOM. Do I need to explicitly send the JavaScript remove
or is there something I'm missing that does it automatically?
Thanks for any suggestions

If you use file:// then the browser is bypassing gnoga and going to the filesystem wherever the browser is running, that is a bad idea even for local desktop apps. Yes, of course. Instead either place the images in to the /img or /html directories or your Gnoga app, or link the directory under /img or /html so will be severed through your Gnoga app. Alternatively just pull from a foreign server location on the web or your network. -- Björn -- Don't Limit Your Business.

Re: [Gnoga-list] problem deleting row of table
I don't really know a lot about how the DOM works, so I'll just ask:
Does this mean if we are manually deleting items and recreating them that
the DOM is ever growing (similar to a memory leak)?
Think of it like this, as long as you are displaying something (or just =
have hidden) it is in the DOM and taking up memory. If you just destroy =
the Gnoga object with out destroying the DOM object you are in a sense =
leaking memory on the DOM side. Usually that is intended behavior. You =
want to leave what ever you created in place. If you don't you can use =
Remove. Keep in mind that if you Remove from the DOM a element that =
contains other elements all of them are also removed from the DOM. One =
more thing, using Remove still takes memory on the browser side until =
you also delete the Gnoga side which remove the reference it maintains =
to the element on the browser side as well.
Since Gnoga doesn't provide customizable dialogs yet for Singleton
I have been hacking this by deleting and recreating views attached to =
another quot;containerquot; view. Is the inflating the DOM with
abandoned =
entries?
To be sure, after hiding the view if you don't plan on using again, I =
would use .Remove to make sure it is out of the DOM completely and then =
when your Gnoga side object finalizes you can be sure all clean on both =
sides.
