这是我的JS文件
var camListApp = angular.module('camListApp', []);
camListApp.controller('Hello', ['$scope', '$http', function($scope, $http){
$http.get('http://localhost:8080/camera/list').then(function(response) {
$scope.records= response.data;
});
}]);
camListApp.controller('Hello2',['$scope', function($scope){
$scope.custom = true;
$scope.toggleCustom = function() {
$scope.custom = ! $scope.custom;
};
}]);

如何在应用中使用两个控制器?因为我无法找到任何方式让他们同时工作。第一个控制器是使用angularjs来使用我的web服务但是这可以工作,我添加了另一个控制器,它使用切换按钮来显示和隐藏。

您的代码存在一些问题。首先,div
不是tr
的子元素的有效元素,因此丢失该元素。
其次,如果您保持当前的范围,则您的custom
属性位于第二个控制器之外:
<!-- the Hello2 controller and its scope is only available on the td
itself and its children. You use your 'custom' property outside of this,
so that won't work -->
<td ng-controller="Hello2"><button ng-click="toggleCustom()">View</button></td>
看看你的范围,你应该只使用第一个控制器,并将代码放在那个:
var camListApp = angular.module('camListApp', []);
camListApp.controller('Hello', ['$scope', '$http', function($scope, $http){
$scope.custom = true;
$scope.toggleCustom = function() {
$scope.custom = ! $scope.custom;
};
$http.get('http://localhost:8080/camera/list').then(function(response) {
$scope.records= response.data;
});
}]);

您的问题的答案是 - 没有,您的 .html 文件可能有一个控制器
但如果您希望重复使用您的逻辑,则可以通过工厂和服务完成 - angularjs docs
另一个必读:angularjs good practice
所以我们将其应用于您的代码
<强> app.js 强>
angular
.module('camListApp', []);
<强> myCtl.controller.js 强>
angular
.module('camListApp')
.controller('myCtl', myCtl);
function myCtl($scope, myFactory) {
var vm = this;
vm.doSomething = myFactory.someFactoryFunction;
}
<强> myFactory.factory.js 强>
angular
.module('camListApp')
.factory('myFactory', myFactory);
function myFactory($http) {
return {
someFactoryFunction: retrieveSomeData
};
function retrieveSomeData() {
$http.get('http://localhost:8080/camera/list')
.then(success)
.catch(error);
function success(response) {
return response.data;
}
function error(response) {
// handle error
}
}
}
<强> view.html 强>
...
<div ng-controller="myCtl">
<button ng-click="vm.doSomething()">View</button>
</div>
...
不确定上面的代码 100%是否正常,没有尝试过,但逻辑保持不变
