Control container contents
ColdFusion provides a variety of ways to set and change container tag contents:
•
You can use bind expressions in the container tag source (or for
cfdiv
,
bind
) attribute. The container then
dynamically updates any time a bound control changes.
•
You can call the
ColdFuson.navigate
function to change the container body to be the contents returned by a
specified URL. This function lets you specify a callback handler to do additional processing after the new content
loads, and also lets you specify an error handler.
