[JavaScript] keeps footer at the bottom of the page (footer all the way at the bottom of the page)

The company version information is always kept at the bottom of the webpage. How can this information be implemented? The following section of JavaScript demonstrates how to keep footer at the bottom of the page. This sectionCodeI am not very perfect in actual use. When pages and controls that contain other JavaScript controls overlap, this is because the onresize and onload operations are not performed on the page body. I hope you can solve the problem later)

Ibottom = Parseint (document. Body. scrollheight );
}

Document. All [ " Lyfooter " ]. Style. pixeltop = Ibottom - Parseint (document. All [ " Lyfooter " ]. Style. Height );
