Troubleshooting Angular and Ionic: Unable to Retrieve Value from HTML Input Element

Check out the HTML code below:

        <div class="list">
            <label class="item item-input">
                <input id="email" ng-model="email" type="text" placeholder="Email Address">
            </label>
            <br> 
            <center>
            <button class="button button-positive" ng-click="getData();"> Test </button>
             </center>
        </div>

Here's the Angular code snippet:

    $scope.getData = function() {
        var emailadd = document.getElementById('email');
        var url = "http://172.16.99.138/sendemail.php?emailaddress="+emailadd;
        console.log(url);
    };

Despite implementing this code, there seems to be an issue when running it as the console fails to locate the variable. Advice and assistance would be greatly appreciated.

Please note that the code in question is incorrect because using document.getElementById('email') will only retrieve the DOM element and not its value.

However, it is recommended to follow the "Angular Way" of doing things:

In your controller, you should define the model like this:

$scope.email = {
    text: ''
};

Then, in your HTML, bind it like this:

<input type="email" name="input" ng-model="email.text" required>

You can then use $scope.email in your method like this:

$scope.getData = function() {
   var url = "http://172.16.99.138/sendemail.php?emailaddress="+$scope.email.text;
   console.log(url);
};

To implement data binding in AngularJs, simply follow these steps: pass the email as a parameter in the function getData()

<div class="form-section">
            <label class="input-label">
                <input id="email" ng-model="email" type="text" placeholder="Enter Email Address">
            </label>
            <br> 
            <center>
            <button class="submit-button" ng-click="getData(email);"> Submit </button>
             </center>
        </div>

Next, update your controller to include the following code:

  $scope.getData = function(email) {
       // var emailadd = document.getElementById('email');avoid this method
        var url = "http://example.com/sendemail.php?email="+email;
        console.log(url);
    };
