(Classic) watch()

watch(<selector>,<action>)

sets a watch on the <selector> item in the current page. When the user performs <action> an event will be fired for that action in the web event domain. <selector> is a jQuery selector such as a class (.foo) or id (#bar). The following web domain actions are available:

pageview
submit
change
click

watch('#foo', 'click')
