如何突出显示ngRepeat中的选定行?

angularjs

我找不到能帮助我解决Angular中这个简单问题的东西。与位置路径进行比较时,所有答案都与导航栏相关。

我使用list和构建了一个动态表ngRepeat。当我单击一行时,我试图为该行分配一个css类(选中),以突出显示该行已被用户选中的事实,并.selected从先前突出显示的行中删除了该行。

我缺少在选定的行和CSS类分配之间进行绑定的方法。

我在每个rowul)上应用了代码,ng-click="setSelected()" 但我缺少function应用更改的逻辑。

我的代码-Plunk

我的代码:

var webApp = angular.module('webApp', []);

//controllers
webApp.controller ('VotesCtrl', function ($scope, Votes) {
    $scope.votes  = Votes;
    $scope.statuses = ["Approved","Pending","Trash","Spam"];

    $scope.setSelected = function() {
       console.log("show");

    }
});

//services
webApp.factory('Votes', [function() {

    //temporary repository till integration with DB this will be translated into restful get query
    var votes = [
        {
            id: '1',
            created: 1381583344653,
            updated: '222212',
            ratingID: '3',
            rate: 5,
            ip: '198.168.0.0',
            status: 'Pending',
        },
        {
            id: '111',
            created: 1381583344653,
            updated: '222212',
            ratingID: '4',
            rate: 5,
            ip: '198.168.0.1',
            status: 'Spam'

        },
        {
            id: '2',
            created: 1382387322693,
            updated: '222212',
            ratingID: '3',
            rate: 1,
            ip: '198.168.0.2',
            status: 'Approved'

        },
        {

            id: '4',
            created: 1382387322693,
            updated: '222212',
            ratingID: '3',
            rate: 1,
            ip: '198.168.0.3',
            status: 'Spam'
        }
    ];

    return votes;
}]);

我的HTML:

  <body ng-controller='VotesCtrl'>
    <div>
    <ul>
        <li class="created">
            <a>CREATED</a>
        </li>
        <li class="ip">
            <b>IP ADDRESS</b>
        </li>
        <li class="status">
            <b>STATUS</b>
        </li>
    </ul>
    <ul ng-repeat="vote in votes" ng-click="setSelected()">
        <li  class="created">
          {{vote.created|date}}
        </li>
        <li class="ip">
            {{vote.ip}}
        </li>
        <li class="status">
            {{vote.status}}
        </li>
    </ul>
   </div>
   </body>

我的CSS(仅选定的类):

.selected {
  background-color: red;
}

每行都有一个ID。您要做的就是将该ID发送给函数setSelected(),将其存储($scope.idSelectedVote例如),然后检查每一行是否所选ID与当前ID相同。这里是一个解决方案(见文档ngClass,如果需要的话):

$scope.idSelectedVote = null;
$scope.setSelected = function (idSelectedVote) {
   $scope.idSelectedVote = idSelectedVote;
};



<ul ng-repeat="vote in votes" ng-click="setSelected(vote.id)" ng-class="{selected: vote.id === idSelectedVote}">
    ...
</ul>
