javascript - 从外部 ng-repeat 获取值

Question

如何从 ng-repeat 外部获取值？这是我从 json 获取值的函数

function($scope, $http) {
        $http.get('https://www.mywebsite.com/images/getimages.php').
          success(function(data, status, headers, config) {
            $scope.walls = data.walls;
            console.log($scope.walls);
         }).error(function(data, status, headers, config) {
            // called asynchronously if an error occurs
            // or server returns response with an error status.
         });

然后我有一张 table :

<tr ng-repeat="wall in walls">
                <td>{{wall.id}}</td>
                <td><a href="#" ng-click="">{{wall.link}}</a></td>            
            </tr>

i 将显示在表格外的 div 中，因此在 ng-repeat 之外，{{wall.link}} 从 td 中选择。我该怎么做？

您可以实现 Controller 功能来设置选定的墙对象:

function ($scope, $http) {

    $http.get('https://www.mywebsite.com/images/getimages.php')
        .success(function (data, status, headers, config) { /*...*/ })
        .error(function (data, status, headers, config) { /*...*/ });

    $scope.select = function (wall) {
        $scope.selectedWall = wall;
    };
}

以及您将使用的 HTML

<table>
    <tr ng-repeat="wall in walls">
        <td>{{wall.id}}</td>
        <td>
            <a href="#" ng-click="select(wall)">{{wall.link}}</a>
        </td>
    </tr>
</table>

<div>{{selectedWall.link}}</div>
