The strain on the When method of jquery

Requirement: A, b two tasks are processed (whether a, B is successful or failed), and the following tasks are performed.
Code Listing 1:

Java code

4. var leftresult = Leftpromise.then (
6. function (value) {
8. Console.info ("Jsona End");
10. }, function () {
12. Console.info ("Jsona fail");
14. }
16. );
20. var rightresult = Rightpromise.then (
22. function (value) {
24. Console.info ("jsonb End");
26. }, function () {
28. $ ("#jsonB"). Val ("");
30. Console.info ("jsonb fail");
32. }
34. );
38. $.when (Leftresult, Rightresult). Always (
40. function () {
42. Console.info ("Start compare");
44. });

You may be able to perform the following tasks directly after the a task fails.
The When method is defined as any failure, or all success is executed down. What do we do?
Through a always-on packaging solution:

Java code

4. var leftresult = Leftpromise.then (
6. function (value) {
8. Console.info ("Jsona End");
10. }, function () {
12. Console.info ("Jsona fail");
14. }
16. ). Always (
18. function () {
20. Console.info ("Jsona always");
22. var d = $. Deferred ();
24. D.resolve ();
26. return d.promise ();
28. }
30. );
32. var rightresult = Rightpromise.then (
34. function (value) {
36. Console.info ("jsonb End");
38. }, function () {
40. $ ("#jsonB"). Val ("");
42. Console.info ("jsonb fail");
44. }
46. ). Always (
48. function () {
50. Console.info ("jsonb always");
52. var d = $. Deferred ();
54. D.resolve ();
56. return d.promise ();
58. }
60. );
62. $.when (Leftresult, Rightresult). Always (
64. function () {
66. Console.info ("Start compare");
68. });

The point here is that after then there is a Always,always method that returns must be successful, allowing the When method to satisfy the conditions that are successfully executed down.
