Article Introduction：Detailed explanation of JS bubbling events and event capture examples

2016-12-05 comment 0  1440

Article Introduction：js bubbling event is an event model used to describe how events propagate in the DOM structure. This model is based on the concepts of event bubbling and event capture. Event bubbling is part of the event model, which describes how when a specific event occurs on an element, the event propagates to the upper layers of the DOM structure. If an event occurs on an element, the event will not only be triggered on the element, but also on its parent element, the parent element's parent element, and so on, until it reaches the outermost element, usually the document object. This process is called event bubbling.

Article Introduction：js bubbling events include click, dblclick, mouseover, mouseout, mousemove, mousedown, mouseup, keydown, keyup, input, change, submit, focus, blur and scroll, etc. Detailed introduction: 1. Click event, which is triggered when the user clicks the mouse button. The click event is triggered on the target element and then bubbles up on the parent element; 2. dblclick and so on.

Article Introduction：JS bubbling event example analysis: To master how to use bubbling events to achieve interactive effects, specific code examples are needed. With the development of the Internet, JavaScript (JS) has become an important technology in front-end development. In front-end development, JS bubbling events are often used to achieve interactive effects. This article will introduce the basic concepts and usage of JS bubbling events through specific code examples, and analyze how to use bubbling events to achieve some common interactive effects. 1. The basic concept of JS bubbling events. In HTML documents, the element structure often

Article Introduction：What are the situations in JS events that will not bubble up? Event bubbling (Event Bubbling) means that after an event is triggered on an element, the event will be transmitted upward along the DOM tree starting from the innermost element to the outermost element. This method of transmission is called event bubbling. However, not all events can bubble up. There are some special cases where events will not bubble up. This article will introduce the situations in JavaScript where events will not bubble up. 1. Use stopPropagati

Article Introduction：Events that do not bubble up in js include focus events, error events, cancellation events, loading events, storage events, update start events, update completion events, etc. Detailed introduction: 1. Focus events are events triggered when an element gains or loses focus, such as focusin and focusout. These events will not bubble up. They will only be triggered on the current element and will not be passed to outer elements; 2. Error events are events that are triggered when an error occurs, such as error. The error event will not bubble up. It will only be triggered on the current element and will not be passed to outer elements, etc.

Article Introduction：Detailed explanation of JS bubbling events: In-depth understanding of the principle of event bubbling requires specific code examples. Event bubbling is an important concept in JavaScript, and it plays an important role in browsers. By understanding the principle of event bubbling, we can better understand the propagation process of events in the DOM tree, and then handle events flexibly. 1. The principle of event bubbling Event bubbling means that when an element in the DOM tree triggers an event, the event will be propagated to the superior elements in order from back to front. To put it simply, the event will start from the touch

Article Introduction：How to obtain bubbling elements in js requires specific code examples. Event bubbling means that when an event on an element is triggered, its upper parent element will also receive the event. In JavaScript, bubbling elements can be obtained through event objects. Below, I'll give you a concrete code example to explain how to get the bubbling element. First, we need an HTML page with nested elements like this:

Article Introduction：For nested div elements, if both the parent and child elements are bound to some events, the event of the parent element may be triggered when the innermost child element is clicked. Here is an example of js blocking default events and js blocking event bubbling. , please use it as a reference

Article Introduction：Solving the problems caused by JS bubbling events: To understand how to handle bubbling events at once, you need specific code examples. When writing JavaScript code, we often involve event processing. An important concept in event processing is bubbling events. A bubbling event means that when an event on an element is triggered, its parent elements will also trigger the same event in turn. While this mechanism can be very useful in some situations, it can sometimes cause problems. This article will introduce how to handle bubbling events and provide specific code examples.
