javascript add event listener to multiple elements

Показать описание
adding event listeners to multiple elements in javascript is a common task when you want to apply the same behavior to a group of elements. the `addeventlistener` method allows you to attach an event handler to an element, which will be triggered when a specified event occurs.
here's a step-by-step tutorial on how to add event listeners to multiple elements in javascript:
1. **select the elements**: the first step is to select the elements to which you want to attach the event listeners. you can use methods like `queryselectorall` to select multiple elements based on a css selector.
2. **loop through the elements**: once you have selected the elements, loop through them using a loop like `foreach` or a traditional `for` loop.
3. **add event listener**: for each element, add an event listener using the `addeventlistener` method. specify the event type (e.g., 'click', 'mouseover', 'keydown') and the function that should be executed when the event occurs.
here's an example code snippet demonstrating how to add a click event listener to multiple buttons:
in this example, we select all `button` elements on the page and add a click event listener to each button. when a button is clicked, a message is logged to the console indicating which button was clicked.
by following this approach, you can easily add event listeners to multiple elements in javascript and handle events efficiently across a group of elements.
