[英]Convert HTML form into Angular POST request
我有HTML形式的表格,並且嘗試使用前端框架(AngularJS或Angular2)將其轉換為POST請求。 該表格的目的是允許客戶訂閱我的wordpress博客。 我正在嘗試將其從PHP轉換為Angular2(如果有人知道如何將其轉換為AngularJS,我可以從那里轉換為Angular2)。 我該怎么做? POST請求與查詢字符串之間必須有什么內容? 我無法確切了解此表單的每個部分在POST請求中扮演什么角色。
編輯:只是為了澄清,我知道如何使用AngularJS和Angular2,以及如何在兩者中使用HTTP服務。 我想知道如何將表單轉換為請求的正文/查詢字符串。
<form action="/blog/" class="form-inline" role="form" method="POST" accept-charset="utf-8" id="subscribe-blog">
<!-- add hidden inputs for wordpress jetpack widget -->
<input type="hidden" name="action" value="subscribe" />
<input type="hidden" name="source" value="http://www.mywebsite.com/blog/" />
<input type="hidden" name="sub-type" value="widget" />
<input type="hidden" name="redirect_fragment" value="blog_subscription-2" />
<label class="sr-only" for="exampleInputEmail">Email address</label>
<input type="email" class="form-control wide" id="exampleInputEmail" placeholder="Enter email address">
<button type="submit" name="jetpack_subscriptions_widget" class="btn btn-submit">Subscribe</button>
</form>
符合這種思路的東西正確嗎?
postForm() {
var body = {
action: 'subscribe',
source: 'http://www.mywebsite.com/blog/',
sub-type: 'widget',
redirect_fragment: 'blog_subscription-2',
email: 'clientEmailAddress@gmail.com', // don't think this is right
// not sure what to do with `jetpack_subscriptions_widget` attribute on the submit button either
};
return this.http.post(`http://www.mywebsite.com/blog/`, body)
.map(res => res.json())
.toPromise()
.then(data => {
return data;
});
}
您需要包括angular.min.js
和script.js
HTML
<body ng-app="myApp" ng-controller="myCtrl">
<input type="text" ng-model="name" />
<input type="submit" value="Send" ng-click="send(name)"/>
</body>
角度js代碼: script.js
angular.module('myApp', [])
.controller('myCtrl', ['$scope', '$http', funtion($scope, $http){
$scope.name = ""; // intially the input field is empty. As you type in the input field, the value will be updated here.
$scope.send = function(name){
alert(name);
var url = $scope.name; // try to enter an url
$http.get(url).then(function Success(res){
// here you can do anything with res
}, function Error(err){
alert(error);
})
}
}]);
使用angular將應用程序分成幾部分:
如果您要完全通過端點 (后端服務, REST或任何其他端點)角度發出http請求,通常在這種情況下:
ng-model
,例如<input type="text" ng-model="val">
。 在您的情況下,您的html將類似於: HTML
<form ng-submit="send()" class="form-inline" role="form" accept-charset="utf-8" id="subscribe-blog">
<!--no need of 'action' attribute in the form since the post will be done using angular-->
<!-- add hidden inputs for wordpress jetpack widget -->
<input type="hidden" name="action" value="subscribe" ng-model="subscribe"/>
<input type="hidden" name="source" value="http://www.mywebsite.com/blog/" ng-model="source"/>
<input type="hidden" name="sub-type" value="widget" ng-model="widget" />
<input type="hidden" name="redirect_fragment" value="blog_subscription-2" ng-model="redirect_fragment"/>
<label class="sr-only" for="exampleInputEmail">Email address</label>
<input type="email" class="form-control wide" id="exampleInputEmail" placeholder="Enter email address" ng-model="email">
<button type="submit" name="jetpack_subscriptions_widget" class="btn btn-submit">Subscribe</button>
</form>
然后在控制器中,您可以根據需要處理所有ng-model ,然后將這些值傳遞給這樣的(角度)服務
//....angular controller
function send(){
//..collect params using the ng-models
var params = [];
params['email'] = $scope.email; //here you define 'email' as the name of the param received by the webservice as input !!!
myService.sendValues(params).then(function(data){
})
}
...您最終將這些值發送到php服務,如下面的代碼:
//... angular service
function sendValues(params){
var url = "miendpointurl/subscribe";
//... at this pont in params you have all those params you named like 'email', 'subscribe' and so on
return $http.post(url, params).then(function(response){
return response.data;
},
function(responseOnError){
return responseOnError.data;
}
}
Angular將與您透明地與php服務進行交互,並將為您提供服務器響應。
