Angular ng-click 在 ng-repeat 中不起作用

Angular ng-click not working in ng-repeat

我试图在 ng-repeat 中使用 ng-click 将数组元素保存在另一个变量中,但是当我单击该元素时,它不起作用。

这是我的代码:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
  <meta charset="utf-8">
  <title>JS Bin</title>
</head>
<body ng-controller="myCtrl">
  <div ng-repeat="img in images">
    <a ng-click="showing = img">{{img.descricao}}</a>
  </div>

  --------------------
  Clicked element description is: {{showing.descricao}}
</body>
</html>

这是我的 javascript:

var app = angular.module("myApp", []);

app.controller("myCtrl", function($scope) {
      $scope.images = [
        {
            "id": 1,
            "image": "http://placehold.it/300x300",
            "ordem": 1,
            "descricao": "Descricao 1"
        },
        {
            "id": 2,
            "image": "http://placehold.it/300x300",
            "ordem": 2,
            "descricao": "Descricao 2"
        }
    ];

  $scope.showing = {};
});

我哪里错了?

我认为您在更改 ng-repeat 中显示的值时使用不正确,因为 ng-repeat 创建自己的范围。相反,您应该绑定一个函数来为 $scope.showing 设置值。 例如:


    $scope.changeShowing = function(img) {
        `$scope.showing = img;`
    };

ng-click ="changeShowing(img)"'
