In the following code, I am adding a customer to a table based on information from the form.
I found that the ng-submit
will not send the form variables to addCustomer()
unless the input element has both ng-model
and name
and they both have the same name, although I couldn't find this documented anywhere.
Why is this the case? And since this seems to be redundant, and I passing the variables correctly?

Normally you would create a customer object, and then bind ngModel to its properties.
In your ngController, initialize your newCustomer:
var mainModule = angular.module('mainModule', []);
mainModule.controller('mainController', function ($scope) {
$scope.idCount = 1;
$scope.customers = [];
$scope.newCustomer = { id: $scope.idCount, firstName:'', lastName:''};
$scope.addCustomer = function (customer) {
$scope.customers.push(customer);
$scope.newCustomer = { id:++$scope.idCount, firstName:'', lastName:''};
};
}
In your HTML, bind ngModel to the customer's first name and last name poperties - unless you need to do form validation, the name attribute is not necessary.
<form ng-submit="addCustomer(newCustomer)" role="form">
<div class="form-group">
<label for="firstName">First Name:</label>
<input type="text" class="form-control" ng-model="newCustomer.firstName" />
</div>
<div class="form-group">
<label for="lastName">Last Name:</label>
<input type="text" class="form-control" ng-model="newCustomer.lastName"/>
</div>
<button type="submit" class="btn btn-default">Add</button>
</form>
