Javascript: Is there a way to specify infinite input parameters for Parse.Promise.when?
javascript,parse.com,promise,.when
No, but there will be. ECMAScript 6 features rest parameters which allow you to do this: Parse.Promise.when(promises).then(function(r1, r2, r3, ....rest) { console.log(r1); // prints 1 console.log(rest); // an array with the rest of the parameters. }); In EcmaScript 5 you need to use arguments: Parse.Promise.when(promises).then(function() { console.log(arguments[0]); // prints 1...

How to use jQuery.when() with an array of URLs?

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'); }); ...

If you simplify this and ignore the array/apply portions, you...
Wait until all ajax queries in each() function are finished using $.when()
Ok, I found it! var resp_error = false; var ajax_calls = []; $(".items").each(function() { ajax_calls.push(ajax_item($(this)).done(function(resp){ if (resp.val == 0) return (resp_error = true); })); }); $.when.apply($, ajax_calls).then(function() { if (!resp_error) callback(); }); ...
$.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(); });...
