Question

我以为我正确使用了AngularJS $q界面。但是我传递给then回调的函数永远不会被执行。我在resolve包裹的函数中调用$q。我已经确认正在调用resolve()，但似乎这与.then()链接的函数不同：

$q(function(resolve, reject) {
  resolve();
  reject();
  console.log("This happens");  //This shows that resolve() is being called
}).then(function() {
  console.log("This doesn't");  //Yet this never gets executed
}).catch(function() {
  console.log("This also doesn't happen");
});

输出结果为：

This happens

我做错了什么？

我的环境是使用mocha和sinon-chai进行的KarmaJS单元测试。

您需要致电$rootScope.$apply()。

$q(function(resolve, reject) {
  resolve();
  console.log("This happens");  //This shows that resolve() is being called
}).then(function() {
  console.log("This too!");
});
$rootScope.$apply();

$ q解析函数不会触发
