Application analysis:
Note: The get request of the above code is the server of this site. You cannot copy it directly to your local run. There will be cross-domain problems. The solution is Copy the data of Customers_JSON.php to your own server. Attached: The best solution to PHP Ajax cross-domain problems.
AngularJS applications are defined via ng-app. The application executes within a <div>.
ng-controller directive sets controller Object name.
Function customersController is a standard JavaScript object constructor.
The controller object has a property: $scope.names.
