javascript - how can i sync two Backbone fetch calls with JQuery WHEN and THEN -


i found out cool thing in jquery: can do:

$.when([$.get(..), $.ajax(...), $.getjson(...)]).then(function(data1,data2,data3){          // code run when requests done         });

this great when want sync many ajax calls.

in backbone ajax call being issued every time fetch model or collection:

cardscollection.fetch();

my question how can achieve similar syncing capabilities backbone model/collection fetching:

i like:

$.when([series.fetch(), cardscollection.fetch()]).then(function(){             cardslistview.seriesid = seriesid;             cardslistview.seriesname = series.get('seriesname');             cardslistview.template = _.template(cardslisttemplate);             cardslistview.render();             $('#loader').hide();         });

is possible?

tnx. ;-)

yes, it's possible. pass several deferred jquery.when: $.when(series.fetch(), cardscollection.fetch()).then(...)
