Javascript 将HTML表单转换为角度POST请求
我有这个HTML表单,我正试图使用前端框架(AngularJS或Angular2)将其转换为POST请求。此表单的目的是允许客户订阅我的wordpress博客。我正在尝试将其从PHP转换为Angular2(如果有人知道如何将其转换为AngularJS,我可以从那里转换为Angular2)。我该怎么做?POST请求与查询字符串的主体中必须包含什么?我很难准确理解此表单的每个部分在POST请求中扮演的角色 编辑:我只是想澄清一下,我知道如何使用AngularJS和Angular2,以及如何在两者中使用HTTP服务。我想知道如何将表单转换为请求的正文/查询字符串Javascript 将HTML表单转换为角度POST请求,javascript,html,angularjs,wordpress,post,Javascript,Html,Angularjs,Wordpress,Post,我有这个HTML表单,我正试图使用前端框架(AngularJS或Angular2)将其转换为POST请求。此表单的目的是允许客户订阅我的wordpress博客。我正在尝试将其从PHP转换为Angular2(如果有人知道如何将其转换为AngularJS,我可以从那里转换为Angular2)。我该怎么做?POST请求与查询字符串的主体中必须包含什么?我很难准确理解此表单的每个部分在POST请求中扮演的角色 编辑:我只是想澄清一下,我知道如何使用AngularJS和Angular2,以及如何在两者中使
<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>
您需要包括
angular.min.js
和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);
})
}
}]);
html
<body ng-app="myApp" ng-controller="myCtrl">
<input type="text" ng-model="name" />
<input type="submit" value="Send" ng-click="send(name)"/>
</body>
<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>
使用angular将应用程序拆分为多个部分:
- 视图(html)
- 处理一些验证等(控制器)
- 并进行一些模型逻辑处理(服务)
- 对于需要在请求中发送的每个输入字段,使用
,类似于ng model
。在您的情况下,您的html将类似于:
<body ng-app="myApp" ng-controller="myCtrl">
<input type="text" ng-model="name" />
<input type="submit" value="Send" ng-click="send(name)"/>
</body>
<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>
…最终将值发送到php服务,如下面的代码所示:
//... 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将以透明的方式与php服务交互,并返回服务器响应。您是否有使用Angular(1或2)的经验?“我正在尝试将它从PHP转换为Angular2”是什么意思?我知道您正在使用此表单向php(控制器或任何在后端处理请求的东西)发出请求。是这样吗?我对两者都有很强的经验,并且知道如何对两者提出发帖请求。我想知道如何使用表单中需要的所有数据格式化请求。请参阅。输入需要
ng model
指令。表单需要ng submit
指令。
