This HTML is returned to the web service. Now the callback is made and the function will generate the HTML.It also validates user access to the context (equivalent of calling require_login()) and then adds the context object to parameters as $args so the callback can do additional validation such as permission check. This web service switches the requires manager class to a specific class ( fragment_requirements_manager) for collecting all necessary JavaScript that is included in the html to be returned by the callback function. loadFragment makes an AJAX call to a web service core_get_fragment.When desired a call is made to the loadFragment function with various parameters including the name of the callback that will supply the rendered HTML.The module fragment is included in a JavaScript file.The callback function needs to be located in įor the JavaScript that accompanies this callback, have a look at mod/assign/amd/src/grading_panel.js How it works This function returns a promise that is resolved with HTML and JavaScript. params: Parameters for the callback function.contextid: The context ID for the component.

callback: The callback that you are calling.component: The component for the callback that you will also supply.LoadFragment is the exposed function to use. This JavaScript module is located at lib/amd/src/fragment.js Most of Moodle uses these forms and there seemed no clear way to borrow or create another system that would satisfy all requirements.
Fragment definition code#
Mforms currently do a lot of validation, and include accessibility code and tags. The issue for this was created to allow Moodle mforms to be changed and submitted via AJAX. Fragment.js is an Asynchronous Module Definition (AMD) to allow the inclusion of rendered HTML code and associated JavaScript to be inserted through AJAX onto a page.
