Regarding the AJAX comment… Yeah.. It doesn’t even work on a different port of the same domain. Big pain in my arse. What I’ve taken to doing is just pointing it at a script on my domain, which loads and returns the content of the page/resource on another domain.

if you’re already doing all sorts of trickery with javascript when submitting forms, why not just go with GO, GADGET GO! ???

It’ll hold both images and text and can be styled in whatever way you desire. It’s also easier to select with DOM methods, myForm.getElementsByTagName(“button”) … instead of trying to figure out which one is the button returned in myForm.getElementsByTagName(“input”).

You shouldn’t really be naming your files with spaces in them, everyone knows that’s bad practice… don’t they?

In regards to the input type switching bug:

I usually just replace the element with a new input, created via the DOM. I know it's inconvenient, but I still think it's better than using the display rule.

Regarding “Image inputs in a POST”:

These extra form variable are defined in the HTML standard. (See http://www.w3.org/TR/html4/interact/forms.html#h-17.4)

“When a pointing device is used to click on the image, the form is submitted and the click coordinates passed to the server. The x value is measured in pixels from the left of the image, and the y value in pixels from the top of the image. The submitted data includes name.x=x-value and name.y=y-value where “name” is the value of the name attribute, and x-value and y-value are the x and y coordinate values, respectively.”

Heh…By “by now,” I just meant that you aren’t a beginner and that would have been a beginner mistake. :)

WRT “Image inputs in a POST”: One thing that I have done in the past with the X and Y coordinates was to compile all of the coordinates each day for a certain amount of time and determine where the “hotspots” of the image(s) were. That greatly helped me push my A/B (C/D, etc… hehe) testing of different graphics to increase performance (whatever that meant for a specific page) of the page. Eventually the test would finally reach an equilibrium in performance.

WRT “CSS background with a space”: IMHO, the use of spaces, and to an extent capitalization, in any file that is used/viewed online is flirting with disaster. The space(s) issue has been noted already, but with capitalization you run the risk of yourself or others misspelling the name and causing 404’s, missing images/*.js files, etc. In order to avoid this potential for error, I always try to stick with all lowercase letters and remove/replace spaces for filenames. It’s not always possible (due to pre-existing client code, etc.), but if/when possible I make it happen.

I may be stating the obvious, but the _x and _y post vars submitted when clicking an input type of ‘image’ represent the coordinates on the image where the click occurred. Possibly usable for server side image maps, but as far as i can think there are easier ways of doing pretty much anything you could use this for.
