AngularJS加载服务，然后调用controller并呈现

Question

<div ng-app="app" ng-controller="root">
    <h3>Do not render this before user has loaded</h3>            
    {{user}}
</div>
​

angular.module('app', []).
factory('user',function($timeout,$q){
    var user = {};            
    $timeout(function(){//Simulate a request
        user.name = "Jossi";
    },1000);
    return user;
}).
controller('root',function($scope,user){

    alert("Do not alert before user has loaded");
    $scope.user = user;

});

您可以使用手动初始化延迟angular app的初始化，而不是使用ng-app属性自动初始化。

// define some service that has `$window` injected and read your data from it
angular.service('myService', ['$window', ($window) =>({   
      getData() {
          return $window.myData;
      }
}))    

const callService = (cb) => {
   $.ajax(...).success((data)=>{
         window.myData = data;
         cb(data)
   })
}

// init angular app 
angular.element(document).ready(function() {
       callService(function (data) {
          doSomething(data);
          angular.bootstrap(document);
       });
});

其中callservice是执行AJAX调用并接受成功回调的函数，这将初始化angular App。

还要检查ngcloak指令，因为它可能是您需要的一切。
