Scroll to the top of the page using JavaScript/jQuery
A scrollable page can be scrolled to the top using 2 approaches:
Method 1: Using window.scrollTo():
The scrollTo() method of the window Interface can be used to scroll to a specified location on the page. It accepts 2 parameters the x and y coordinate of the page to scroll to. Passing both the parameters as 0 will scroll the page to the topmost and leftmost point.
Syntax:
window.scrollTo(x-coordinate, y-coordinate)
Example:
html
<!DOCTYPE html><html> <head> <title> Scroll to the top of the page using JavaScript/jQuery? </title> <style> .scroll { height: 1000px; background-color: lightgreen; } </style></head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b>Scroll to the top of the page using JavaScript/jQuery?</b> <p>Click on the button below to scroll to the top of the page.</p> <p class="scroll">GeeksforGeeks is a computer science portal. This is a large scrollable area.</p> <button onclick="scrollToTop()"> Click to scroll to top </button> <script> function scrollToTop() { window.scrollTo(0, 0); } </script></body> </html> |

Method 2: Using scrollTop() in jQuery:
In jQuery, the scrollTo() method is used to set or return the vertical scrollbar position for a selected element. This behavior can be used to scroll to the top of the page by applying this method on the window property. Setting the position parameter to 0 scrolls the page to the top.
Syntax:
$(window).scrollTop(position);
Example:
html
<!DOCTYPE html><html> <head> <title> Scroll to the top of the page using JavaScript/jQuery? </title> <style> .scroll { height: 1000px; background-color: lightgreen; } </style> </head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> Scroll to the top of the page using JavaScript/jQuery? </b> <p> Click on the button below to scroll to the top of the page. </p> <p class="scroll"> GeeksforGeeks is a computer science portal. This is a large scrollable area. </p> <button onclick="scrollToTop()"> Click to scroll to top </button> </script> <script> function scrollToTop() { $(window).scrollTop(0); } </script></body> </html> |
