Basically I want to toggle the value of an element on a page via RJS. I can set the value fine, but I simply cannot figure out how to check the current value. This is essentially what I want to do:
if page["element_id"].value == "0" page["element_id"].value = "1" else page["element_id"].value = "0" end
The assignment lines (e.g. page["element_id"].value = "1") work fine. It's that line to check the current value of the element that is killing me.
Any experience with this?
(Note: I have the RJS Templates for Rails PDF "book", but there is no mention of detecting or assigning values. And as usual, there isn't much else out there on the 'Net.)
