. These proprietary events are typically tailored to the developer's needs, and there are no specifications, so implementations of different browsers may be inconsistent.The following is a summary of the UI events and focus events in JavaScript Advanced programming:UI events refer to events that are not necessarily related to user actions. These events exist in this or that form before the DOM specification appears , and are reserved for backwards com
There are many types of events that can occur in a Web browser. As mentioned earlier, different event types have different information, and the " DOM3 Level Event" Specifies the following types of events:
uiuser interface
Focus event, triggered when the element gets or loses focus; Mouse event: triggered when the user performs an action on the page with the mouse;
Wheel event: triggered when using the mouse wheel (or similar device);
Text event: trig

Object-oriented (object-oriented, OO) languages have a sign that they all have the concept of a class, and that a class can create any number of objects with the same properties and methods. There is no class concept in ECMAScript, so we can use objects to simulate the class. ECMA-262 defines an object as: "A collection of unordered attributes whose properties can contain basic values, objects, or functions." "Strictly speaking, this is equivalent to saying that the object is a set of values tha
Because event handlers can provide interactivity for modern WEB applications, many developers are indiscriminately adding a large number of handlers to the page. In JavaScript, the number of event handlers added to the page will directly affect the overall performance of the page. The causes of this problem are manifold. First, each function is an object, consumes memory, and the more objects in memory, the worse the performance. Second, you must spec
