api 在 Angularjs 中获取数据时更新视图
Update view when api get data in Angularjs
所以,我有一个小问题。我制作了一个使用 omdb api 的小型 Web 应用程序。事情是这样的,当我输入我正在搜索的电影然后按下搜索按钮时,视图应该更改为 result.html 视图并显示我从 api 获得的数据。
api 工作正常。我得到了要显示的数据,但那是在我的 index.html 中。现在我已经使用 ng-routes
拆分了文件
如果你想看的话,我可以给你整个项目。也许我可以将它上传到某处的在线编辑器?
这是我的app.js
var myApp = angular.module("myApp", ['ngRoute']);
myApp.config(['$routeProvider', function ($routeProvider) {
$routeProvider.
when('/home', {
templateUrl: 'views/home.html',
controller: 'filmController'
}).
when('/result', {
templateUrl: 'views/result.html',
controller: 'filmController'
}).otherwise({
redirectTo: '/home'
})
}]);
myApp.controller("filmController", function filmController($scope, $http, $window) {
$scope.getData = function () {
var movieTitle = document.getElementById("filmName").value;
var binding = document.getElementsByClassName("ng-binding");
$http
.get("http://www.omdbapi.com/?t=" + movieTitle + "&apikey=526345a6")
.then(function (response) {
var data = response.data;
if (data.Error) {
alert("Film inte funnen");
return false;
}
for (let key in data) {
if (data.hasOwnProperty(key)) {
let element = data[key];
if (element === "N/A") {
data[key] = "Inget hittat";
if (key === "Poster") {
$scope.post = "Ingen poster hittad";
}
}
$scope.url = data;
}
}
if (data.Ratings.length === 0) {
$scope.rate = "Ingen utmärkelse/er hittad";
}
// This api data is printed to the console on the index.html view, i want it in the result view...
console.log(data);
});
};
});
这是我的index.html
<body>
<div class="main-content">

}
window.applicationCache.addEventListener('updateready',

在我们分解您遇到的问题之前,请注意几点。您似乎没有充分发挥 angularjs 的潜力。混合使用 jquery 和 angularjs 不是最佳实践,并且会使调试变得非常困难。我建议将 movieTitle 设为 ng-model, as well as using angularjs's built in form validation。这将允许您在控制器中轻松访问 movieTitle,并利用 angular 的内置表单控制器和操作。
至于将数据获取到您的其他页面,我会为该页面添加第二个控制器,然后从您的 filmController
,您可以在更改视图时将电影标题作为路由参数传递。在您的 resultController
中,您可以从路由参数中获取电影标题,然后在初始化结果 page/controller.
时执行 api 调用
在您的 home.html
文件中,我们将向输入添加 ng-model
以更加 angularjs 友好。现在我们可以使用 $scope.movieTitle
在控制器中访问 movieTitle
。我也在更改应该在提交时获得 运行 的方法到我添加到 filmController
.
的 search()
方法
home.html
<form ng-submit="search()">
// ... your other html here
<input class="form-control" type="text" name="filmName" id="filmName" ng-model="movieTitle" placeholder="Ex. Armageddon" autofocus>
在您的 filmController
中,我将添加 $location 并将 getData()
方法移动到 resultController
。我们现在将在表单提交时调用 search()
,然后使用 $location
将视图切换到结果视图,将电影标题附加为路由参数,以便我们可以在 resultController
中访问它。
filmController.js
myApp.controller("filmController", function filmController($scope, $http, $location) {
// ... other code you have
// this will be what gets called after the user types a movie title
$scope.search = function () {
var title = $scope.movieTitle; // or using jquery(not recommended)
// this will change location and will produce
// the url: http://[yoursite]/result?movieTitle=title
$location.path('/result').search({movieTitle: title});
}
});
在您新创建的 resultController
中,我们将获取该路由参数并使用它来搜索数据。
resultController.js
myApp.controller("resultController", function resultController($scope, $http, $routeParams) {
// the getData method moved to this controller
$scope.getData = function (movieTitle) {
$http
.get("http://www.omdbapi.com/?t=" + movieTitle + "&apikey=526345a6")
// the rest of your code for getData here
};
// I like to make an init method to make it clear what we are initializing
$scope.init = function () {
// this will get the movieTitle from the /result?movieTitle=title part of your url
var movieTitle = $routeParams['movieTitle'];
// now we call the method you have that uses the omdb api
// just modify it to accept the movie title as a param rather than finding it in the html
$scope.getData(movieTitle);
}
// run init method
$scope.init();
});
最后,您需要更新您的应用配置,让您的 result
路由使用我们添加的 resultController
而不是 filmController
。
