[Seaside] jQuery toggle with a changing image

[Robert Sirois]

Pop both anchors in there and do a show/hide. I think there's a toggle for hidden in there somewhere too.

Subject: [Seaside] jQuery toggle with a changing image

Hello,I'm using a jQuery ajax script to toggle the display of a component. The anchor is initially displayed with a '+' png image. When clicked the hidden div is toggled and the anchor image is changed to a '-'. My code works, but I suspect it is not elegant. What I'd like to do to change the anchor image on each click (and the title), rather than the component replacement I'm doing now.  I tried toggling the class of the anchor div to show different background images, but I could not get that to work (it feels like it should be easy).

Here is what I'm doing now... ('entireContact' is a pre-formatted view of all contact fields in a contact list application).I'd prefer a solution that does not use a server call, which the #html: method requires.

Thanks for any help,Bob 
renderContactToggleOn: html
	html div id: 'contactToggle'; with: [
		self renderContactMoreOn: html].

renderContactMoreOn: html
	html anchor 
		onClick: (			html jQuery ajax script: [:s | 				s << (html jQuery id: 'entireContact') toggle: 0.3 seconds.
				s << (html jQuery id: 'contactToggle') load html: [:r | self renderContactLessOn: r]]);		title: 'Show all contact attributes'; 
		with: [html image url: TSwaFileLibrary / #morePng].  " + "

renderContactLessOn: html

	html anchor 		onClick: (			html jQuery ajax script: [:s | 
				s << (html jQuery id: 'entireContact') toggle: 0.5 seconds.				s << (html jQuery id: 'contactToggle') load html: [:r | self renderContactMoreOn: r]]);
		title: 'Hide contact attributes'; 		with: [html image url: TSwaFileLibrary / #lessPng].  " - "
