In the JavaScript world, there are many APIs that seem to help us know the width and height of web pages , but they are too numerous and easy to confuse and not easily differentiate. Let me explain what these APIs mean, and where the difference is.First, the resolution of the deviceWindow.screen.widthxwindow.screen.heightDesktop: 1440x900/Mobile: 360x640Second, the resolution of the browserWindow.screen.availWidthxwindow.screen.availHeightDesktop chro

The Inavigationprovidercontext method can get an existing menu item, add a menu, or a menu item. As a result, different modules can add their own menus. Once you have created the navigation, you also need to register to the ABP configuration file when the corresponding module is initialized: Configuration.navigation.providers.add Show Me

Javascript API mode: it helps us provide better and cleaner interfaces for functions. These modes mainly include the following: 1) callback mode: The function is also an object, so it can be passed as a parameter. See the following example: function demo01 (callback) {callback ();} function test01 () {console. log ("AAA") ;}demo01 (test01); // "AAA" Let's take a look at the callback and its scope: var myobj

However, Web Worker is actually subject to many restrictions because it cannot truly share memory data and can only use messages for status notifications. Therefore, it cannot even be called a real "multi-thread ". The Web Worker interface is in

If you are not familiar with event events, it is recommended to read my previous text javascript: Understanding DOM events. Or look directly below the worker API.First, we need to instantiate a worker object, and the browser will open a new interface based on the newly created Worker object, which will handle the communication between the client and the INDEXEDDB database.
