The Element.scrollLeft
property gets or sets the number of pixels that an element's content is scrolled to the left.
Note that if the element's direction
of the element is rtl
(right-to-left) then scrollLeft
is 0
when the scrollbar is at its rightmost position (at start of the scrolled content) and then increasingly negative as you scroll towards the end of the content.
Syntax
// Get the number of pixels scrolled var sLeft = element.scrollLeft;
sLeft is an integer representing the number of pixels that element has been scrolled to the left.
// Set the number of pixels scrolled element.scrollLeft = 10;
scrollLeft
can be set to any integer value, however:
- If the element can't be scrolled (e.g. it has no overflow),
scrollLeft
is set to 0. - If set to a value less than 0 (greater than 0 for right-to-left elements),
scrollLeft
is set to 0. - If set to a value greater than the maximum that the content can be scrolled,
scrollLeft
is set to the maximum.
Example
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <style> #container { border: 1px solid #ccc; height: 100px; overflow: scroll; width: 100px; } #content { background-color: #ccc; width: 250px; } </style> <script> document.addEventListener('DOMContentLoaded', function () { var button = document.getElementById('slide'); button.onclick = function () { document.getElementById('container').scrollLeft += 20; }; }, false); </script> </head> <body> <div id="container"> <div id="content">Lorem ipsum dolor sit amet.</div> </div> <button id="slide" type="button">Slide</button> </body> </html>
