我期待像 https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal_img 这样的东西，但在使用 ng-repeat 时它似乎不起作用

angular.module('selectExample', [])
  .controller('ExampleController', ['$scope', function($scope) {
 
    $scope.register = {
      regData: {
        branch: {},
      },
      names: [{
        name:"narquois",
        image:[
        "https://picsum.photos/200",
        "https://picsum.photos/200/300/"]
        
        }],
    };

  }]);

img{
width:70px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="selectExample" ng-controller="ExampleController">
<table id="example" width="100%">
		
   
       <tr ng-repeat="person in register.names">
         <td align="center">{{ person.name }}</td>
         <td align="center"><img ng-repeat="image in person.image" ng-src="{{ image}}"></td>
       </tr>
   
</table> 
</div>

【问题讨论】：

如果你想让你的图像出现在一个模态对话框中，你需要代码来做到这一点。 ng-repeat 仅用于重复项目。
寻求调试帮助的问题（“为什么这段代码不起作用？”）必须包括所需的行为、特定的问题或错误以及在问题本身中重现它所需的最短代码。没有明确问题陈述的问题对其他读者没有用处。请参阅：How to create a Minimal, Complete, and Verifiable example。

【解决方案1】：

请运行以下代码。希望能解决你的问题。

angular.module('selectExample', [])
  .controller('ExampleController', ['$scope', function($scope) {

    $scope.register = {
      regData: {
        branch: {},
      },
      names: [{
        name: "narquois",
        image: [{
          'image': "https://picsum.photos/200",
          'flag': false
        }, {
          'image': "https://picsum.photos/200/300/",
          'flag': false
        }]

      }],
    };
    $scope.getBig = function(key, value) {
      $scope.register.names[0].image[key].flag = true;
    }
    $scope.close = function(key, value) {
      $scope.register.names[0].image[key].flag = false;
    }
  }]);

.imgSmall {
  width: 70px;
}
