我在弄清楚如何将角度控制器中的参数传递给我时遇到了麻烦
服务
服务
#my controller
'use strict';
angular.module('recipeapp')
.controller('recipeCtrl',['$scope','recipeService',function($scope,recipeService){
$scope.recipeFormData={};
$scope.recipeSave = function(){
recipeService.saveRecipe();
}
}]);
#my service
'use strict';
angular.module('recipeapp').service('recipeService',['$http',function($http){
this.saveRecipe = save;
function save(callback){
//calling external http api
}
}]);
我在这里要做的是,从我的表单获取$scope.formData并且控制器应该将其传递给服务,根据我的理解,我不能在服务中使用$scope所以我需要找到一种传递$的方法scope.formData到服务
艰难的想法,在控制器中,recipeService.saveRecipe($scope.formData);但我不确定如何从服务中收集,
当我更改服务this.saveRecipe(val)= save;它不起作用:(
任何帮助都会得到满足
此示例演示了角度应用程序的正确结构：
原文链接：https://www.f2er.com/angularjs/141702.html>控制器内的模型初始化
>实现服务单例,并注入您的控制器
>使用$http promises异步调用Web API调用,并允许服务的调用者处理其成功/失败.
>使用“控制器作为”语法从控制器公开函数,而不是直接从作用域公开函数.
>双向数据模型绑定(文本框到配方和配方到文本框)
在控制器中初始化模型：
angular.module('recipeapp')
.controller('recipeCtrl',recipeService){
// initialize your model in you controller
$scope.recipe={};
// declare a controller function that delegates to your service to save the recipe
this.saveRecipe = function(recipe) {
// call the service,handle success/failure from within your controller
recipeService.saveRecipe(recipe).success(function() {
alert('saved successfully!!!');
}).error(function(){
alert('something went wrong!!!');
});
}
}]);
在配方服务中,定义saveRecipe函数：
angular.module('recipeapp').service('recipeService',function($http){
// expose a saveRecipe function from your service
// that takes a recipe object
this.saveRecipe = function(recipe){
// return a Promise object so that the caller can handle success/failure
return $http({ method: 'POST',url: '/api/recipe/add',data: recipe});
}
}]);
将食谱对象绑定到视图中;添加一个按钮来调用saveRecipe控制器功能并保存配方(传入模型配方对象)：
<div ng-app="recipeapp" ng-controller="recipeCtrl as ctrl">
<form name="recipeForm">
Recipe Name: <input type="text" ng-model="recipe.name" />
<button ng-click="ctrl.saveRecipe(recipe)">Save Recipe</button>
</form>
</div>
