img src on img clickjj

我正在用angularjs创建一个座位预订系统。席位以矩阵形式显示。并且要求是每当我选择一个空座位时，img src应该改为所选座位。img src on img clickjj

在Angularjs的学习曲线中，我不确定如何实现这一点。我的HTML显示座位布局是动态生成的。我正在使用指令在运行时嵌入HTML。还使用指令来处理图像上的图像src变化点击。

我的HTML

<body> 
    <h1>Compile dynamic HTML</h1> 
    <div ng-controller="MyController"> 
     <textarea ng-model="html"></textarea> 
     <div dynamic="html"></div> 

    </div> 
    </body>

我的控制器

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

app.directive('dynamic', function ($compile) { 
    return { 
    restrict: 'A', 
    replace: true, 
    link: function (scope, ele, attrs) { 
     scope.$watch(attrs.dynamic, function(html) { 
     ele.html(html); 
     $compile(ele.contents())(scope); 
     }); 
    } 
    }; 
}); 

app.directive('change-on-click', function() { 
    return { 
     restrict: 'A', 
     link: function($scope, element,attrs){ 
      element.bind('click', function(){ 
       attrs.$set('src', 'C:/Users/vk0044682/Desktop/dynamic/dynamic/assets/images/ac_sleeper_selected.jpg'); 
      }) 
     } 
    } 
}); 

function MyController($scope,$sce) { 
    $scope.click = function(arg) { 
    alert('Clicked ' + arg); 
    }

你的属性必须是蛇的情况下在你的HTML，但骆驼案件在您的指令定义：

app.directive('changeOnClick', function() {

非常感谢。这样一个小错误。再次感谢 – VikramK

有没有什么方法可以在我的指令中获得像src或title这样的其他特性的价值？ – VikramK

您可以通过attr对象（传递给您的链接函数的第三个参数）获取它们：attr.src，attr.title – pixelbits
