我是新的離子框架。目前我正在研究離子iOS應用程序。我需要做一些不喜歡的功能。由於我有多個記錄來自網絡服務,對於每條記錄,我必須將類似,不喜歡和評論總數的功能並將這些信息保存到databaseIONIC:喜歡不喜歡`ng-repeat`內的功能

還改變CSS的喜歡和不喜歡的按鈕。

我不明白如何建立這個功能到我的app.Please幫我做到這一點。

試試這個方法:

angular.module('main',[]).controller('mainController', function($scope, $http){ 
 

 
    $scope.items = [ 
 
    {"id":1,"title": "item1", "like": false}, 
 
    {"id":2,"title": "item2", "like": true}, 
 
    {"id":3,"title": "item3", "like": false}, 
 
    {"id":4,"title": "item4", "like": true}, 
 
    {"id":5,"title": "item5", "like": false}, 
 
    {"id":6,"title": "item6", "like": true}, 
 
    {"id":7,"title": "item7", "like": false}, 
 
    {"id":8,"title": "item8", "like": false}, 
 
    {"id":9,"title": "item9", "like": true}, 
 
    {"id":10,"title": "item10", "like": false}, 
 
    
 
    
 
    ]; 
 
    
 
    $scope.toggle_like = function(item){ 
 
     
 
     //send item.id to HTTP Call to change id in DB and execute following statement in success callback 
 
     item.like = !item.like; 
 
    
 
    } 
 

 
})
.fake_link:hover{ 
 
cursor:pointer; 
 
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.0/angular.min.js"></script> 
 
<div ng-app="main" ng-controller="mainController"> 
 
<table> 
 
<thead> 
 
    <tr> 
 
    <th> Title </th> 
 
    <th> Like </th> 
 
    
 
    </tr> 
 

 
</thead> 
 
<tbody> 
 
    <tr ng-repeat="item in items"> 
 
    <td> {{item.title}} </td> 
 
    <td ng-click="toggle_like(item)" class="fake_link"> <span ng-if="item.like"> Unlike </span> <span ng-if="!item.like"> Like </span> </td> 
 
    </tr> 
 

 
</tbody> 
 
</table> 
 
</div>

我已經嘗試過它的工作正常,但我也想改變計數增加或減少喜歡和不喜歡。 – Nupur

你可以使用underscore.js,或者你可以用下面的代碼來計算喜歡的東西: (編輯toggle_like函數) function toggle_like(item){ item.like =!item.like; $ scope.liked = $ scope.items.filter(function(item){return item.like;})。length; //和不喜歡的總是$ scope.items.length - $ scope.liked; } – user3597009
