event bubbling vs capturing

What is the blocking event bubbling method in jquery? This article has prepared two ways to prevent event bubbling, the difference between the two ways. Return false not only prevents the event from bubbling up, but also prevents

1, by returning false to cancel the default behavior and prevent the event from bubbling. JQuery Code: $ ("form"). Bind ( "submit", function () {return false; } ); 2. By using the Preventdefault () method, only the default behavior is canceled. JQuery Code: $ ("form"). Bind ( "submit", function (event) { event.preventdefault (); }

Click a box to pop up, but sometimes you don't want to operate it. You just want to click a blank space to hide the box. The following is a specific implementation:Most of the time, we have such a small function when doing front-end operations. Click a box to pop up. However, if you don't want to operate it, you just want to click a blank space to hide the box. In the following scenario, click a small button to bring up a modal box. This is simple, but we want to hide the modal box when you clic

. First, we have to block bubbling. Otherwise, clicking the button actually triggers the above two events, modal cannot be displayed, but it is actually popped up and hidden immediately. Besides, when we have many widgets in the modal box, it is difficult to judge the clicks in the modal box. Here, I think there is one of the most classic methods, which is simple but clever, First, listen to an event for

The JS bubbling mechanism means that if an element defines event A, such as the Click event, if the event is triggered and the bubbling event is not blocked, then the event propagates t

When using the JS event, the outer element event may be triggered by an event in the inner element, such as clicking on the outer layer of the inner element and triggering a click, which is called event bubbling.$ ( Document). Ready (function(e) { $ ("#wai"). Click (funct

In front-end development, due to browser compatibility and other issues, we often use "Stop event bubbling" and "Block browser default behavior ". 1. Stop event bubbling JavascriptCode // If the event object is provided, this is a non-IE browserIf (E E. stoppropagation)/

Example of JavaScript blocking event bubbling, javascript example Previously, I encountered an event bubble problem and went to the Internet to search for it. Most of the results were the same code, and the post was not very smooth. When FF is involved, you can use e. stopPropagation ();. Somehow I did not succeed. However, I found that FF supports e. cancelBubbl

This is a basic article. It uses JavaScript to observe the event bubbling mechanism in the Dom and describes how to block default behavior and how to organize event bubbling. 1.

Description: Prevents events from bubbling onto the DOM tree, which is the event handler on any predecessor element that is not triggered. Version added:1.0 Event.stoppropagation () We can use event.ispropagationstopped () to determine whether this method has been invoked (on that event object). This method is also valid for trigger ()-defined events. Note tha

I learned an event bubbling mechanism today and thought it was a bit problematic. I tested it myself and shared the results with you, which helps you better understand the event bubbling mechanism. For example: After you click "hello", f1 will pop up, and f2 f3 will pop up. Then, when the sub-tag generat

JQuery. Event provides a very simple method to prevent event bubbles: Event. stopPropagation (); The code is as follows:Copy code $ ("P"). click (function (event ){Event. stopPropagation (); // do something}) However, this method does not work for events bound
