Mini version of deferred

Directly paste the Code:

/*** Mini version of deferred */function deferred (func) {If (this instanceof deferred === false) {return New deferred (func)} var tuple = []; vaR promise = {resolve: function () {var t; while (t = tuple. shift () {T. apply (null, arguments) ;}}, then: function (n) {return tuple. push (N), this ;}}if (func) {func. call (promise, promise. RESOLVE);} return promise ;}

Demo1:

VaR d = new deferred (); setTimeout (function () {d. resolve ({Name: 'breezefeng', age: 24, sex: 'male'}) ;}); D. then (function (globalinfo) {console. log (globalinfo. name );}). then (function (globalinfo) {console. log (globalinfo. age );}). then (function (globalinfo) {console. log (globalinfo. sex );});

Demo2:

Deferred(function (resolve) {    setTimeout(function () {        resolve(‘aaaa‘);    });}).then(function (bbb) {    console.log(bbb)})
