UI-Router state.go 回调状态变化 [英] UI-Router state.go call back on state change

问题描述

当 state.go 成功调用时，我需要一个回调，并设置我的警报消息.当前，在调用 state.go 之后，消息被推送到数组.State.go 调用控制器，包含警报消息的数组设置为空.

I need a callback when state.go has been invoked successfully, and set my alert message. Currently the message is pushed to the array, after state.go has been called. State.go calls the controller, and the array containing the alert message is set to empty.

结果，不会显示任何警告信息.

Result, no alert message will be shown.

控制器:

$scope.alerts = []; // empty array, initialized on startup
.....
// This could be any function
.success(function(data, status, headers, config, statusText){
     $state.go($state.current, {}, {reload : true});
     $scope.alerts.push({type : 'success', msg : status});
})
.error(function(error){
    console.log(error.message);
});

推荐答案

$state.go() 返回一个promise.

$state.go() returns a promise.

所以做一些类似的事情:

So do something like:

$state.go('wherever', {whenever: 'whatever'}).then(function() {
  // Get in a spaceship and fly to Jupiter, or whatever your callback does.
});
