chaining

If i have promise = userService.updateUser($stateParams.userId, req); promise.then( function(user) { logger.logSuccess('Updated user'); $scope.resetForm(); WizardHandler.wizard().goTo(0); return user; }, function(error) { logger.logError('Ups an error has occurred'); console.error('error updating user: ' + error); } ); promise.then(function(user) { _.each(uploader.getNotUploadedItems(), function(item) { return item.formData.push({ id: user.id }); }); }); Then if the updateUser fails the log will be shown and then second then will not be executed however if i have promise = userService

Is there a good design pattern for utilizing promises, while still supporting chaining? For example, let's say that we have something like: function Foobar() { this.foo = function() { console.log('foo'); return this; }; this.bar = function () { console.log('bar'); return this; }; } var foobar = new Foobar(); foobar.foo().bar(); If instead we change the methods to use promises, e.g. function Foobar() { this.foo = function() { var self = this; return new Promise(function (resolve, reject) { console.log('foo'); resolve(self); }); }; ... } Is there a good way to do something like: var foobar = new

I have this code: jQuery('#flash').animate({opacity: 0.35}, 200) .animate({opacity: 0}, 200) .animate({opacity: 0.35}, 200) .animate({opacity: 0}, 200) .animate({opacity: 0.35}, 200) .animate({opacity: 0}, 600) and I'm not decided on how many times I want its state altered. Is there a way to chain animations programmatically instead having to add/remove chain elements by editing the animate chain? No, you can't chain animations without editing the animation queue. If you want to chain a variable, but limited number of times you can do easily with a loop: var flash = $("#flash"); for (var i=0;

So I was working with jQuery's .load() just now and it looks like we can't configure $("#example").load('./uri.ext #ID') to chain as such: $("#example").load('./uri.ext #ID1').load('./uri.ext #ID2').load('./uri.ext #ID3') Which of course would be useful if we had a template file of DIVs or something to dynamically build a page and not store the HTML in a string variable or something along those lines... plus, we could keep several of these in one file. Ideally I would like to nest things as such with that command: <div id="example"> <div id="ID1"> <div id="ID2"> <div id="ID3"> </div> </div> <

I read this article on the mathworks blog about functional programming in matlab, and two of the helper functions there were: paren = @(x, varargin) x(varargin{:}); curly = @(x, varargin) x{varargin{:}}; The obvious third one to complete the trio (and in keeping with the five-letter theme) would be: acces = @(x, field) x.(field); Putting the discussion of whether it's a good idea to implement chaining in this manner or not in matlab aside (note: octave supports chaining by default), paren seems to work well, as expected; however, curly and acces have a major drawback; consider the following

This question already has an answer here: Variadic curried sum function 12 answers I have written code to achieve sum(1)(2) //3 the code looks like: function sum(a) { return function(b) { return a+b } } But I didn't work out the second question, which is how to achieve any arbitrary number of chain function call like: sum(1)(2) == 3 sum(5)(-1)(2) == 6 sum(6)(-1)(-2)(-3) == 0 sum(0)(1)(2)(3)(4)(5) == 15 Normally you'd do something like this: var add = function(a,b){ return a+b; }; var sum = function(){ return [].reduce.call(arguments, add); } And then you can write: sum(1,2,3,4); // 10 But it

e.g. class tester { @Test public void testBeanUtils() throws InvocationTargetException, IllegalAccessException, NoSuchMethodException { Stranger stranger = new Stranger(); BeanUtils.setProperty(stranger,"name","wener"); BeanUtils.setProperty(stranger,"xname","xwener"); BeanUtils.setProperty(stranger,"yname","ywener"); System.out.println(stranger); } @Data// lombok annotation generate all setter and getter public static class Stranger { @Accessors(chain = true)// generate chained setter String name; String xname; String yname; public Stranger setYname(String yname)// no lombok, still not work {
