Hi folks,
I'm creating several divs which represent "rows" of a "table". It's not
really a table though, it's table-like using divs and spans. It works
great. Just the way I want.
But...
I'm trying to make it so that when you click on one of the "rows" it
changes the background color. It already does this on mouseover and
mouseout, and that works great. When clicking the row highlights and
stays highlighted whether the user rolls over it or not. This works
great for all but the very last row. When I click on the last row
nothing happens. If I attempt to alert its "RowState" (On/Off i.e.
selected/not selected), I get the "nodeName is null or not an object" error.
Basically, the user creates this "table" on the fly, by choosing dates
from a calendar (along with some other items on the screen) and clicking
"add". This information is written to a structure on my server using
ajax and the array indexes that were added to the structure get
returned. These index numbers get attached to each "row" so that I can
identify it later (like when the user wants to remove it).
The following are the two functions involved (the one that makes the
ajax call and makes the divs) and the other is the click handler. There
is a div (not shown) with an ID of "OrderList".
NOTE: The double pounds (##) are not a mistake. This is the way
ColdFusion escapes the pound sign. So that's not any part of it.
Can anybody tell me what the heck I'm doin' wrong here? :o/
Cheers,
Chris
PS. There is a side issue I'm having in that for the "rows" that will
highlight properly, it's a bit slow. probably a second to a
second-and-a-half before the background color changes. Is there a better
way I should be doing this? I'm trying to use classes instead of
changing the css directly (i.e. $("#ID").css("backgroundcolor", "red");
). Thanks again! Chris
