Subviews calling methods

[Shell (Aridhia Informatics)]

Hi guys,

We're breaking a rather complex page into subviews. View 'A' contains subview 'B' and 'C'. View B generates a string which needs to be passed to view C for display purposes. While we have several 'dirty' ways that would probably work, we think there must be an elegant way / best practice for passing data from one subview to another. Any suggestions?

This is what we've done to get it working, whether or not it's "best practice" or not remains to be seen :)

view b)

chorus.pageEvents.broadcast( "ourEvent", { message: "foo" } );

view c)

this.subscribePageEvent("ourEvent", this.handleThatEvent );

...

handleThatEvent: function( param ) {
    console.log( param.message ); // => "foo"
}

Hi Shell,

Normally when we see a pattern like this, it means we should use a shared object (possibly a backbone model) to generate and hold that string.  If this doesn't work, sometimes we will use page events like your example.  Sometimes we will include a pointer to B in C so that C can ask directly for the string.  The shared object is certainly the cleanest method.

Hi Charles,

Thanks. We've decided to keep our messaging pattern - while not ideal, we can't really move the data or data generation into a model as it's a 3rd-party jquery plug-in that's the culprit...
