Angular-js:如何在ng-if中使用ng-click [英] Angular-js: How to use of ng-click with ng-if

问题描述

我已经在angular JS中创建了一个聊天框，现在我想在单击任何用户时显示通知气泡.我尝试将其与ng-click和ng-if一起使用，但失败了. 这是我正在使用的代码

I have created a chatbox in angular JS and now I want to show notification bubble when ever I click on any user. I tried to use this with ng-click and and ng-if but failed. Here is the code I am using

     <div class="people"  >
            <div ng-repeat="user in allCompanyUsers">
                <div class="person" ng-click="activateChat(user)" id="chat_{{user.id}}">
                    <img alt="" />
                    <span class="name" >{{user.firstName}} {{user.lastName}}
                    <span   ng-show="!user.showNotification" class="noti_bubble">5</span> 


                    <span class="preview"></span>
                </div>
            </div>
        </div>  

在控制器端:

    $scope.showNotification = false;

    $scope.allCompanyUsers = AllCompanyUsers.query();

    $scope.activateChat = function(user){
        console.log(user);

        $scope.activeConversations = [];
        UserMessages.query({toUser:user.login}).$promise.then(function(data) {
               angular.forEach(data, function(message) {
                   $scope.activeConversations.push({'message':message.message,'type':message.type, 'time': message.time});
               });
        });

        $scope.activePerson=user.login;
        $scope.showNotification = true;
        $scope.isDisabled=true;
            /*$scope.activeConversations=user.chat;*/
        $('.left .person').removeClass('active');
        var el = angular.element( document.querySelector('#chat_'+user.id));
        el.addClass('active');   
    };

当前，该计数是硬编码的. 这里所有用户都显示5个气泡，但我希望只有选中的用户才能显示气泡...

Currently the count is hardcoded. Here All users are showing with 5 bubble but I want that only selected user will show the bubble...

任何帮助都将受到赞赏.预先感谢

any kind of help is appreciated. Thanks in advance

推荐答案

如果您想将其与ng-if一起使用:

If you wabt to use it with ng-if :

<div ng-if="bubble">
    //bubble code : set bubble to false when it close
    // use currentUser variable
</div>

<button ng-click="currentUser = user;bubble=true"></button>

请注意，我为ng-click更改了按按钮的div，因为我不确定whetver div元素是否支持click事件，因此请选择button或a或select标记.

Note that i changed div by button for ng-click, because i'm not sure whetver div element support click event, so go for button or a or select tag.
