How to tell when multiple functions have completed with jQuery deferred

You need to first make each of these functions return the deferred object jQuery gives you when you make an AJAX request. Then you can put those in to an array, and apply that to $.when(). Something like this: var deferreds = []; $.ajax({ url: url, cache: false, beforeSend: function(){...
When and Deferred
Use $.map instead of $.each. This returns an array of the Deferred objects returned by your iteration function, and these can then be passed to $.when. $.when.apply(null, $.map(function(index, file) { return self.fileRead.read(file).done(function(fileB64) { self.fileShow(file, fileB64, fileTemplate); }); })).done(function() { console.log('done'); }); ...

$.when with arrays of functions is not working properly
jquery,ajax,jquery-deferred,.when
$.when does not accept or expect an array of functions, it expects an array of deferreds. You need to invoke your functions, and pass the promises in. var topPriorityPromises = []; topPriorityFunctions.push(showDiv()); topPriorityFunctions.push(getData()); $.when.apply($, topPriorityPromises ).then(function () { // ... If you simplify this and ignore the array/apply portions, you...
$.when.apply.done not executing asynchronous functions
javascript,jquery,ajax,asynchronous,.when
Your anonymous function has no return so its effective return value is undefined. So, first you need to fix your anonymous function to include a return: functions.push(function() { return $.ajax(...); }); You can also make a cleaner implementation of your invocation loop: var requests = functions.map(function(f) { return f(); });...
