Changing a link when a button is focused

Basically I am going with an application style site for mobile view and they wanted a button on the bottom to flip through the pages in order while the nav at the top allows you to flip through them in any order. I want to change the bottom button to link to the following page depending on which one it is on. so I want the button to change links when specific buttons are focused. I tried many different things and can not seem to make it work. Please do your magic.

if(document.getElementById("abt").hasFocus()) {
document.getElementById("golink").href = "#work";

}
