Question

我已配置angularjs文件，以便在我按导航栏中的“添加项目”按钮时加载视图，但是当我尝试提交表单时没有任何反应。但是如果我单独加载php文件它没有任何问题，并将数据添加到我的json文件。

这是提交之后的样子

Answer 1

这里很少有错误，

我没有看到将action属性设置为php资源路径的表单。
要提交表单，您应该有一个提交类型的按钮。有点像这样。

<html>
<body>

<form action="welcome.php" method="post">
Name: <input type="text" name="name"><br>
E-mail: <input type="text" name="email"><br>
<input type="submit">
</form>

</body>
</html>

您的PHP文件可以是

<html>
<body>

Welcome <?php echo $_POST["name"]; ?><br>
Your email address is: <?php echo $_POST["email"]; ?>

</body>
</html>

我希望这有助于您解决此问题

要使表格正常工作＆＃34;角度方式＆＃34;，您需要一对来指定一些额外的位。

您首先需要在打开html标记之后使用ng-app这个名称来表示该代码块将会被观看＆＃39;通过角度模块（您也将在代码中指定）。

您还需要在表单中添加ng-controller标记，然后在您的javascript中引用

如果表单已成功验证，请在角度表单中添加ng-click以发送表单以提交表单：ng-click=”formsubmit(userForm.$valid)”

以下是一些sample code：

<!DOCTYPE html>
<html ng-app="formExample">
    <head>
        <title>simple form with AngualrJS</title>
        <link rel="stylesheet" href="css/bootstrap.min.css" type="text/css" />
        <script src="js/angular.js" ></script>
        <script src="js/formjs.js"></script>
    </head> 

    <body>

        <div ng-controller="formCtrl">
            <form  name="userForm"  class="well form-search"   >

                <input type="text" ng-model="name" class="input-medium search-query" placeholder="Name" required >
                <input type="email" ng-model="email" class="input-medium search-query" placeholder="Email" required >
                <input type="text" ng-model="message" class="input-medium search-query" placeholder="Message" required >
                <button type="submit" class="btn" ng-click="formsubmit(userForm.$valid)"  ng-disabled="userForm.$invalid">Submit </button>

            </form>
            <pre ng-model="result">
                {{result}}
            </pre>
        </div>
    </body>

</html>

 JS:
<pre class="lang:default decode:true " title="formjs.js" >
/**
 * @filesource : formjs.js
 * @author : Shabeeb  <mail@shabeebk.com>
 * @abstract : controller fo HTML page
 * @package sample file 
 * @copyright (c) 2014, Shabeeb
 * shabeebk.com/blog
 * 
 *  */
var app = angular.module('formExample', []);
app.controller("formCtrl", ['$scope', '$http', function($scope, $http) {
        $scope.url = 'submit.php';
        $scope.formsubmit = function(isValid) {


            if (isValid) {
                $http.post($scope.url, {"name": $scope.name, "email": $scope.email, "message": $scope.message}).
                        success(function(data, status) {
                            console.log(data);
                            $scope.status = status;
                            $scope.data = data;
                            $scope.result = data; 
                        })
            }else{            
                  alert('Form is not valid');
            }
        }
    }]);</pre> 

 submit:

<?php
/**
 * @filesource : submit.php
 * @author : Shabeeb  <mail@shabeeb.com>
 * @abstract : simple submission php form
 * @package sample file 
 * @copyright (c) 2014, Shabeeb
 * 
 * 
 *  */

$post_date = file_get_contents("php://input");
$data = json_decode($post_date);


//saving to database
//save query

//now i am just printing the values
echo "Name : ".$data->name."n";
echo "Email : ".$data->email."n";
echo "Message : ".$data->message."n";



?>

使用ng-view加载表单时不提交表单
