AngularJS 数据属性的绑定值

看起来没有问题仍然没有。 分析模板，以及我的控制器加载数据，但在分析模板时，还没有数据。 我需要数据的指令在那里，同时它只是收集空的macodas。

在团队的帮助下，我解决了这个问题 $watch:

$scope.$watch/'ready', function// {

 if/$scope.ready == true/ {

 //now the data-id attribute works

 }

}/;

然后当控制器加载所有材料时 ajax, 你来弄吧：

$scope.ready = true;

在我看来，你真正需要什么， - 这是
http://docs.angularjs.org/api/ng.%24q
:

// for the purpose of this example let's assume that variables '$q' and 'scope' are

// available in the current lexical scope /they could have been injected or passed in/.



function asyncGreet/name/ {

 var deferred = $q.defer//;



 setTimeout/function// {

 // since this fn executes async in a future turn of the event loop, we need to wrap

 // our code into an $apply call so that the model changes are properly observed.

 scope.$apply/function// {

 if /okToGreet/name// {

 deferred.resolve/'Hello, ' + name + '!'/;

 } else {

 deferred.reject/'Greeting ' + name + ' is not allowed.'/;

 }

 }/;

 }, 1000/;



 return deferred.promise;

}



var promise = asyncGreet/'Robin Hood'/;

promise.then/function/greeting/ {

 alert/'Success: ' + greeting/;

}, function/reason/ {

 alert/'Failed: ' + reason/;

/;

编辑：就是正确的，这里是使用控制器和绑定使用承诺的简单示例：

var app = angular.module/'myApp', []/;



app.controller/'MyCtrl', function/$scope, $q/ {

 var deferredGreeting = $q.defer//;

 $scope.greeting = deferredGreeting.promise;



 /**

 * immediately resolves the greeting promise

 */

 $scope.greet = function// {

 deferredGreeting.resolve/'Hello, welcome to the future!'/;

 };



 /** 

 * resolves the greeting promise with a new promise that will be fulfilled in 1 second

 */

 $scope.greetInTheFuture = function// {

 var d = $q.defer//;

 deferredGreeting.resolve/d.promise/;



 setTimeout/function// {

 $scope.$apply/function// {

 d.resolve/'Hi! /delayed/'/;

 }/;

 }, 1000/;

 };

}/;​

基本上，这个想法是你可以关联承诺，它将一旦异步答案允许它就会才能执行。
