喜欢和不喜欢用户angular度审查产品

用户架构：

var UserSchema = new Schema({ review_likes : [{type:String}], review_dislikes : [{type:String}] }); 

审查模式：

 var ReviewSchema = new Schema({ productID:{type: String, required: true}, numoflikes:{type:Number, required:true}, numofdislikes:{type:Number, required:true} }) 

审查控制器：

  .controller('reviewsController', function($route, reviewsFactory, $scope, $routeParams){ var that=this; reviewid = $routeParams.id; productID = $routeParams.id; likestats = false; dislikestats = false; /* console.log('controller',questionid) */ var getallReviews = function(){ reviewsFactory.getReviews(function(data){ that.reviews = data; }) } getallReviews(); var getProReviews = function(productID){ reviewsFactory.getProductReviews(productID, function(data){ that.proreviews = data; }) } getProReviews(productID); $scope.pID=productID; this.addReview = function(){ reviewsFactory.addReview(this.newReview, function(message){ getallReviews(); console.log(message) that.messages = message }) this.newReview = {}; } var getthatReview = function(){ reviewsFactory.getthatReview(reviewid, function(data){ /* console.log('[CONTROLLER] That Question:',data); */ that.review = data; }) } getthatReview(); this.getThatReview = function(){ reviewsFactory.getthatReview(reviewid, function(data){ /* console.log('[CONTROLLER] That Question:',data);*/ reviewsFactory.checkRevLike(reviewid, function(response){ if(response == "liked"){ data.likestats = true; } else{ data.likestats = false; } angular.forEach(that.proreviews,function(e){ if(e._id == reviewid)e.likestats = data.likestats; }); angular.forEach(that.reviews,function(e){ if(e._id == reviewid)e.likestats = data.likestats; }); }) that.review = data; }) } this.addlikereview = function(rId){ reviewid = rId; reviewsFactory.addRevLike(rId, function(response){ that.getThatReview(); }) } this.removelikereview = function(rId){ reviewid = rId; reviewsFactory.removeRevLike(rId, function(response){ that.getThatReview(); }) } this.checklikereview = function(review){ reviewid = review._id; reviewsFactory.checkRevLike(review._id, function(response){ if(response == "liked"){ review.likestats = true; } else{ review.likestats = false; } }) } this.getThatReview2 = function(){ reviewsFactory.getthatReview(reviewid, function(data){ /* console.log('[CONTROLLER] That Question:',data);*/ reviewsFactory.checkRevDisLike(reviewid, function(response){ if(response == "disliked"){ data.dislikestats = true; } else{ data.dislikestats = false; } angular.forEach(that.proreviews,function(e){ if(e._id == reviewid)e.dislikestats = data.dislikestats; }); angular.forEach(that.reviews,function(e){ if(e._id == reviewid)e.dislikestats = data.dislikestats; }); }) that.review = data; }) } this.adddislikereview = function(rId){ reviewid = rId; reviewsFactory.addRevDisLike(rId, function(response){ that.getThatReview2(); }) } this.removedislikereview = function(rId){ reviewid = rId; reviewsFactory.removeRevDisLike(rId, function(response){ that.getThatReview2(); }) } this.checkdislikereview = function(review){ reviewid = review._id; reviewsFactory.checkRevDisLike(review._id, function(response){ if(response == "disliked"){ review.dislikestats = true; } else{ review.dislikestats = false; } }) } }) 

HTML：

  <div ng-controller="reviewsController as revCtrl "> <div ng-repeat="review in revCtrl.proreviews> <div ng-init="revCtrl.checklikereview(review)"> LIKE <div ng-if="review.likestats" ng-href="#" ng-click="revCtrl.removelikereview(review._id)" class="glyphicon glyphicon-star "> </div> <div ng-if="!review.likestats" ng-href="#" ng-click="revCtrl.addlikereview(review._id)" class="glyphicon glyphicon-star-empty "> </div> <span ng-bind="review.numoflikes"></span> </div> <div ng-init="revCtrl.checkdislikereview(review)"> DISLIKE <div ng-if="review.dislikestats" ng-href="#" ng-click="revCtrl.removedislikereview(review._id)" class="glyphicon glyphicon-star "> </div> <div ng-if="!review.dislikestats" ng-href="#" ng-click="revCtrl.adddislikereview(review._id)" class="glyphicon glyphicon-star-empty "> </div> <span ng-bind="review.numofdislikes"></span> </div> </div> </div> 

我试图喜欢/不喜欢审查列表中的问题

我想限制1个喜欢/不喜欢1个用户的评论

这里出现的问题是，在html中的显示，graphics成功立即变化，但ng-bind =“review.numoflikes”和ng-bind =“review.numofdislikes”的跨度不是即时更新，而是在页面上更新刷新

数据库正在成功更新

另外，如果你能帮我限制用户喜欢或不喜欢的话，那就太好了。 谢谢。

find了一个解决scheme..只是尝试一次

 this.getThatReview = function(){ reviewsFactory.getthatReview(reviewid, function(data){ /* console.log('[CONTROLLER] That Question:',data);*/ reviewsFactory.checkRevLike(reviewid, function(response){ if(response == "liked"){ data.likestats = true; } else{ data.likestats = false; } angular.forEach(that.proreviews,function(e){ if(e._id == reviewid)e.likestats = data.likestats; }); angular.forEach(that.reviews,function(e){ if(e._id == reviewid)e.likestats = data.likestats; }); angular.forEach(that.proreviews,function(e){ if(e._id == reviewid)e.numoflikes = data.numoflikes; }); angular.forEach(that.reviews,function(e){ if(e._id == reviewid)e.numoflikes = data.numoflikes; }); }) that.review = data; }) } this.getThatReview2 = function(){ reviewsFactory.getthatReview(reviewid, function(data){ /* console.log('[CONTROLLER] That Question:',data);*/ reviewsFactory.checkRevDisLike(reviewid, function(response){ if(response == "disliked"){ data.dislikestats = true; } else{ data.dislikestats = false; } angular.forEach(that.proreviews,function(e){ if(e._id == reviewid)e.dislikestats = data.dislikestats; }); angular.forEach(that.reviews,function(e){ if(e._id == reviewid)e.dislikestats = data.dislikestats; }); angular.forEach(that.proreviews,function(e){ if(e._id == reviewid)e.numofdislikes = data.numofdislikes; }); angular.forEach(that.reviews,function(e){ if(e._id == reviewid)e.numofdislikes = data.numofdislikes; }); }) that.review = data; }) }
