Oracle JET(OJET) 面试题与答案

问题 31. How RequireJS is linked with Oracle JET (OJET)?

Oracle JET includes RequireJS, a third party JavaScript library that you can use in your app to load only the Oracle JET libraries you need. Using RequireJS, you can also implement lazy loading of modules or create JavaScript partitions that contain more than one module.

RequireJS is a JavaScript file and module loader that simplifies managing library references and is designed to improve the speed and quality of your code.

RequireJS implements the Asynchronous Module Definition (AMD) API which provides a mechanism for asynchronously loading a module and its dependencies.

Oracle JET's modular organization enables app developers to load a subset of needed features without having to execute require() calls for each referenced object. Each Oracle JET module represents one functional area of the toolkit, and it typically defines more than one JavaScript object.

问题 32. How to work with controls in Oracle JET (OJET)?

Oracle JET includes buttons, menus, and container elements to control user actions or display progress against a task. For HTML elements such as simple lists, you can use the standard HTML tags directly on your page, and Oracle JET will apply styling based on the app's chosen theme.

For example, you can use the oj-button element as a standalone element or include in oj-buttonset , oj-menu, and oj-toolbar container elements.

Navigation components such as oj-conveyor-belt, oj-film-strip, and oj-train use visual arrows or dots that the user can select to move backward or forward through data.

To show progress against a task in a horizontal meter, you can use the oj-progress-bar element. To show progress against a task in a circle, you can use the oj-progress-circle element.

问题 33. How to work with forms in Oracle JET (OJET)?

Oracle JET includes classes to create responsive form layouts and components that you can add to your form to manage labels, form validation and messaging, input, and selection. The input components also include attributes to mark an input as disabled or read-only when appropriate.

问题 34. How to work with Layout and Navigation in Oracle JET (OJET)?

Use the Oracle JET oj-accordian, oj-collapsible, oj-dialog, oj-drawer-*, oj-flex*, oj-masonry-layout, oj-navigation-list, oj-panel, oj-popup, oj-size*, and oj-tab-bar components and patterns to control the initial data display and allow the user to access additional content by expanding sections, selecting tabs, or displaying dialogs and popups.
