我是angularJS初学者,我遇到了问题.
我想使用控制器内脚本中声明的对象将数据添加到html中的媒体对象,但是我找不到必须使用的指令.
这是代码：
<!DOCTYPE html>
<html lang="en" ng-app="confusionApp">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- The above 3 meta tags *must* come first in the head; any other head
content must come *after* these tags -->
<title>Ristorante Con Fusion: Menu</title>
<!-- Bootstrap -->

this.dish = dish;
});

</html>有人可以帮我吗？我认为这很容易,但是知道我已经崩溃了！
谢谢
解决方法:
您至少有2个选择.
选项1：使用$scope.这将确保您的html保持不变
app.controller('dishDetailController', function($scope) {
// Your dish declaration
$scope.dish = dish;
});
选项2：JavaScript保持不变.在HTML中,因为您将dishDetailController用作dishCtrl,所以在盘上添加有ishishCtrl
例如：使用< img class =“ media-object img-thumbnail” ng-src = {{dish.image}} alt =“ Uthapizza”>代替
<img class="media-object img-thumbnail" ng-src={{dishCtrl.dish.image}} alt="Uthapizza">
