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.

$http.get() Read static JSON data from the web server.

The server data file is: http://www.php.cn/try/angularjs/data/Customers_JSON.php.

When loading JSON data from the server, $scope.names becomes an array.


NoteThe above code can also be used to read database data.
