angularjs form submission not registering any data

Greetings to everyone.

I am looking for a way to display the data in my form, which currently returns an empty object when I try to log it using $scope.subMe.

The form element looks like this:

<form name="myForm" ng-submit="subMe()">
  <input type="text" name="name" value="" />
</form>

I have several input elements in the form and would like to know the best practice for checking the validity of the form on the backend. Is it recommended to use something like the following code snippet?

var _valid = $http.post();
if ( _valid) {
  if ( createUserSuccess() ){
    showSucceess();
  } else {
    showError();
  }
} else {
  showBadFilledFormElements();
}

Any advice or insights would be appreciated. Thank you!

If you don't have a submit input or button, then using ng-submit to view form data would not be appropriate.

To start, create an empty object within the scope of your form like this:

myApp.controller('formController', function($scope) {
  $scope.formData = {};

  $scope.processForm = function() {
      // do something when form is submitted
  }
});

Next, bind the ng-model in your HTML markup as shown below:

<div ng-controller="formController">
   <form name="myForm" ng-submit="processForm()">
       <input type="text" name="name" ng-model="formData.name" value="" />
       <button type="submit">Submit</button> 
   </form>
    {{formData}}
</div>

You can display the form data using {{formData}} within the formController scope.

EDIT: Changed the submit form function name for clarity.

Eric Olson's response is mostly accurate. I wanted to provide an additional insight here. You may want to explore ngForm

ngForm

An alternative name for the form directive. In HTML, nesting of form elements is not allowed. Using ngForm can be beneficial when nesting forms is necessary, such as determining the validity of a subgroup of controls.

It is important to note that while ngForm serves the purpose of grouping controls, it does not replace the functionality of the <form> tag with all its capabilities (e.g., submitting data to the server).

Ensure that you include models in the input fields of your form:

<form name="myForm" ng-submit="submitForm()">
  <input type="text" name="name" value="" ng-model="myForm.name" />
  <input type="text" name="email" value="" ng-model="myForm.email" />
</form>

Additionally,

$scope.submitForm = function(){
  console.log( $scope.myForm ); // { name: "abc", email: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7716151437031204035914181a">[email protected]</a>"}
}

I may not fully grasp the second part of your inquiry, but it is advised to establish an Angular Service for efficient practices when sending form data to your api.
