我在AngularJs中构建单页应用程序,我需要调用Facebook UI对话框。如果用户单击“确定”或“取消”,则successReport方法不会立即调用。此方法在我点击页面中的任何按钮后调用,或link。类似于内部队列
service.showStreamDialog=function (json) {
if (json.stream) {
var newCardSentId = json.cardSentId;
FB.ui(json.stream, function (resp) {
if (resp && resp.post_id) {
reportService.successReport(newCardSentId,newCardSentId,resp.post_id);
} else {
reportService.cancelReport(newCardSentId);
}
});
}
};
//在其他档案中
var successReport=function(cardId,cardSentId,postId){
var defered = $q.defer();
$http.post(reportUrl,$.param({
cardId:cardId,
cardSentId:cardSentId,
postId:postId,
accessToken: ACCESS_TOKEN
}))
.success(function(data){
defered.resolve(data);})
.error(function(data){
defered.reject(data);
});
return defered.promise;
};
我发现了问题。它是在我的应用程序集成facebook api。我添加$ rootScope。$ apply call, 并且所有工作都按我的预期进行
service.showStreamDialog = function (json) {
if (json.stream) {
var newCardSentId = json.cardSentId;
FB.ui(json.stream, function (resp) {
if (resp && resp.post_id) {
$rootScope.$apply(function () {
$rootScope.$broadcast('CARD_SENT_SUCCESS', {cardSentId: newCardSentId,post_id:resp.post_id});
});
} else {
$rootScope.$apply(function () {
$rootScope.$broadcast('CARD_SENT_CANCEL', {cardSentId: newCardSentId});
});
}
});
}
};
