event bubbling vs capturing

In JavaScript Dom operation will definitely encounter JS bubbling event, most commonly is the div pop-up window event solutionWhen clicking on the gray part of the pop-up window disappears, clicking on the Black section has no effect.The following section of code to analyze the bubbling

The bubbling event is a click on the child node, which triggers the parent node, the ancestor node's click event.Here is the HTML code section:The corresponding jquery code is as follows:When you click Span, the div and body click events are triggered. Clicking on a div triggers the body's Click event.How do you prevent this bubbling

As each element is triggered in the document, it will bubbleIf there are alert events on each layer, then the inner div is triggered, the outer layer, the outermost layer.To prevent interference between events, you need to block event bubbling.General use of e.stoppropagation ();IE8 and below do not support, need to use e.cancelbubble=false;Another e is the global object used to get the window. E can use any other letter or Word instead, such as a,b,c

div id = "Content" > outer div element span > inner span element span > outer div element div > div id = "MSG" > div > $(function(){ //binding The Click event for a SPAN element$ (' span ').

1, when the user browsing the page , the browser will explain or compile the page code-this process is essentially through the event to drive, that is, when the page is loaded, execute a Load event, in this event to implement the browser to compile the page code process. The event is triggered into two phases, one is c

JQuery provides two ways to block event bubbling. Mode one: Event.stoppropagation (); Copy Code code as follows: $ ("#div1"). MouseDown (function (event) { Event.stoppropagation (); }); Mode two: return false; Copy Code code as follows: $ ("#div1"). MouseDown (function (event) { return fal

Today, a problem is encountered, the same element in the component is bound to multiple identical events, a, a, a callback function in the A event returns a Boolean type value, if True then continue, if False then return directly;So let's look at a few ways to block events in an event object:1. Event.preventdefault (); --Block The default event for an element.Not

JQuery provides two methods to prevent event bubbles. The following describes the two methods and specific application cases. Method 1: event. stopPropagation (); $("#div1").mousedown(function(event){event.stopPropagation();}); Method 2: return false; $("#div1").mousedown(function(event){return false;}); The two method

There are very important features in JavaScript events-event bubbling: Gossip Less, let's illustrate everything by observing the following code: If you click on runs The Click event is triggered whenever we click formdiv If we click on P, the browser will execute alert (' P ') in turn; Alert (' div ');Alert (' form '). This means that when an

Jquery provides two methods to prevent event bubbles. Method 1: event. stoppropagation (); $ ("# Div1"). mousedown (function (event ){Event. stoppropagation ();}); Method 2: Return false; $ ("# Div1"). mousedown (function (event ){Return false;}); However, the two methods ar

Stop event bubbling and "block browser default behavior" are frequently used in front-end development work due to browser compatibility issues. 1. Block browser default behavior [Java] View plain copy Functionstopdefault (e) { //If an event object is provided, this is a non-ie browser if (ee.preventdefault) { 　　//block default browser actions (web) E.pr

In the front-end development work, because of browser compatibility issues, we often use "stop event bubbling" and "block browser default behavior." 1. Stop event bubbling JavaScript code If an event object is provided, this is a non-ie browser if (e e.stoppropagation)

The bubbling event and event monitoring in JSBubbling EventJS "Bubble Event" is not practical use of fancy tricks, it is a sequence of JS event execution mechanism, "bubbling algorithm" in the programming is a classic problem,

Let's take a look at a JavaScript event bubbling example. There is a button in the div element, and they are all bound to a click event, which is a precondition for event bubbling. When you click on the button, there will be two warning boxes, one for the button's click

1.E.preventdefault () block event default behaviorE.preventdefault ();----according to English meaning, such as: $ ("#xx").

Yes, you are right, return false does so many things. It's been used repeatedly because it loo
