海外TECH	DEV Community	Event Bubbling - JavaScript Concepts Simplified	https://dev.to/thisurathenuka/event-bubbling-javascript-concepts-simplified-8bi	Event Bubbling JavaScript Concepts SimplifiedHello guys welcome to another article in the JavaScript Concepts Simplified article series Today we ll be looking into Event Bubbling in JavaScript I m just going to go through some of the basic things you need to know before going into the main event Background KnowledgeAn event is an action or an occurrence that happens in your system The simplest example would be the user clicking on a button For each event that is fired we can write an event handler A JavaScript function to handle the event to do what we want to do For example we can write an event handler function to print something on the screen once the user clicks on the button We also have event listeners in JavaScript Event listeners listen to the events happening So if we want to print something on the screen once the user clicks on the button we need to first create an event listener to listen for the click event of the button When we are loading HTML pages in browsers the browser creates a tree like structure for each page called the DOM For example if you have a button inside your body tag the path to the button element would be html gt body gt button Three Phases of Event HandlingWhen it comes to handling events modern browsers have three phases Capturing PhaseTarget PhaseBubbling Phase The Capturing PhaseThe browser checks to see if the element s outer most ancestor has an onclick event handler registered on it for the capturing phase and runs it if so Source MDN Docs The Target PhaseThe browser checks to see if the target property has an event handler for the click event registered on it and runs it if so Then if bubbles is true it propagates the event to the direct parent of the selected element then the next one and so on Otherwise if bubbles is false it doesn t propagate the event to any ancestors of the target Source MDN Docs The Bubbling PhaseThe browser checks to see if the direct parent of the element selected has an onclick event handler registered on it for the bubbling phase and runs it if so Source MDN Docs Wait What It is hard to grasp the issue by reading the above lines Let me simplify Here is the issue we are facing Think you have created a UI with two div blocks Block A and Block B Block B is placed inside Block A And you have created event handlers for the click event of both div tags Now when you click on Block B before calling B s event handler the browser calls A s event handler function Obviously this is not what we expected When we click on B only the event handler of B should be called How do we fix this Luckily we do have a solution for this In the event object we have a function called stopPropogation You can call this function at the start of the event handler function of B You will see that only the event handler function of B is getting executed this time When is Event Bubbling Useful There could be some use cases where this can be useful For example when you have a list of items and you want to do something for all of the items you will usually have to add event listeners for all the items But since you now know the concept of event bubbling you can just write and assign the event handler for the parent node and see the magic happen This concept is called event delegation You can read more on that in this article Thank you for reading the article Hope you learned something valuable today And most importantly stay safe guys	2021-09-18 17:30:10
