Javascript set left style doesn't work

Question

xpos=xpos+1;
document.getElementById(\"img\").style.left=xpos;

I can\'t assign xpos value to left property in javascript.

Answer 1

Try adding a unit to it. Otherwise it's probably not being read by the browser due to it being invalid CSS

document.getElementById("img").style.left= xpos + "px";

You can usually figure out these kind of things by looking at the styles pane of your browser's developer tools
