How to scroll to specific element using jQuery ?
Many times, in our website we want to scroll automatically to a section of the webpage when we click on a button or a heading in a navbar or a list. So, to achieve this automatic scrolling to the required element, we need to take the help of jQuery. Using jQuery, we can achieve this in a very simple way. But first we need to understand two methods namely scrollTop() and offSet() in jQuery.
scrollTop() method: It helps to get the current vertical position of the scrollbar of the first element, in the set of all matched elements.
scrollTop() method: It is used to set the vertical position of the scroll bar to the value ‘val’.
offSet() Method: It is used to get the coordinates of the first element in the set of all matched elements.
Example 1: This example describes how to scroll a specific element using jQuery.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content= "width=device-width, initial-scale=1.0"> <script src= integrity= "sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"> </script> <title> How to scroll to specific item using jQuery? </title> <style> div { color: #0f9d58; border: 3px solid #0f9d58; width: 200px; height: 100px; overflow: auto; } p { width: 300px; height: 300px; } </style> </head> <body> <div class="demo"> <h1>Heading</h1> <p>paragraph</p> </div> <script> var container = $('div'); var scrollTo = $('p'); // Calculating new position of scrollbar var position = scrollTo.offset().top - container.offset().top + container.scrollTop(); // Setting the value of scrollbar container.scrollTop(position); </script> </body> </html> |
Output:
Example 2: In this example, we will see how to scroll to different sections of the page by clicking different buttons, along with a scrolling effect.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content= "width=device-width, initial-scale=1.0"> <script src= integrity= "sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"> </script> <title> How to scroll to specific item using jQuery? </title> <style> div { color: #0f9d58; border: 3px solid #0f9d58; margin: 10px; width: 200px; height: 100px; overflow: auto; } p { width: 300px; height: 300px; } button { margin: 10px; } </style> </head> <body> <div class="demo"> <h1>Heading</h1> <p id="p1">paragraph 1</p> <p id="p2">paragraph 2</p> </div> <button onclick="scrollParagraph1()"> paragraph 1 </button> <button onclick="scrollParagraph2()"> paragraph 2 </button> <script> var container = $('div'); // Scrolls to paragraph 1 function scrollParagraph1() { var scrollTo = $("#p1"); // Calculating new position // of scrollbar var position = scrollTo.offset().top - container.offset().top + container.scrollTop(); // Animating scrolling effect container.animate({ scrollTop: position }); } // Scrolls to paragraph 2 function scrollParagraph2() { var scrollTo = $("#p2"); // Calculating new position // of scrollbar var position = scrollTo.offset().top - container.offset().top + container.scrollTop(); // Animating scrolling effect container.animate({ scrollTop: position }); } </script> </body> </html> |
Output:
