In the following code, when I delete a customer, I want the TR row to disappear.
What is the best way to do this? Do I need to send the row as a parameter to deleteCustomer somehow? Do I have access to the TR DOM element within AngularJS somehow?

<script>
var mainModule = angular.module('mainModule', []);
function mainController($scope) {
$scope.loggedActions = [];
$scope.customers = [
{id: 1, firstName: 'Joe', lastName: 'Thompson'},
{id: 2, firstName: 'Hank', lastName: 'Howards'},
{id: 3, firstName: 'Zoe', lastName: 'Frappe'}
];
$scope.deleteCustomer = function (customer) {
$scope.$emit('customerDeleted', customer);
};
$scope.$on('customerDeleted', function (event, customer) {
$scope.loggedActions.push({action: 'delete', description: 'Deleted customer ' + customer.firstName + ' ' + customer.lastName});
});
}
</script>

Here on click of delete button our deleteRow() function gets fire and using splice we remove the selected rows. Conclusion: Directive ng-repeat is used to Bind data to our HTML table. Directive ng-click is applied on the Delete button which fires deleteRow() function. And with splice remove the selected row.
Another significant difference between ng-click and onclick is the execution context. Code inside an onclick attribute executes against the global window object, while an expression inside of ng-click executes against a specific scope object, typically the scope object representing the model for the current controller.
The ng-click directive tells AngularJS what to do when an HTML element is clicked.
When an HTML is clicked, the ng-click directive tells the AngularJS script what to do. In this article, we will learn how to get many/multiple functions to the ng-click directive passed, in just one click. The key is to add a semi-colon (;) or a comma (,). All the functions must be separated by a (;) or a (, ).
as pointed out by @K.Toress's comment, it's better to retrieve the index of the deleted customer via indexOf() from within the function, rather than passing $index from the ng-repeat. passing $index will give unexpected results if using a filter or sorting the array.
deleteCustomer function:
$scope.deleteCustomer = function (customer) {
var index = $scope.customers.indexOf(customer);
$scope.customers.splice(index, 1);
$scope.$emit('customerDeleted', customer);
};

you can use the $index provided by ng-repeat, and array.splice from within the delete function:
html:
<button ng-click="deleteCustomer($index, customer)">Delete</button>
js:
$scope.deleteCustomer = function ($index, customer) {
$scope.customers.splice($index, 1);
$scope.$emit('customerDeleted', customer);
};
