Edit: My answer is valid assuming you want to focus when the page loads

Better use autofocus attribute.

In general, using javascript to set focus automatically isn't a good idea, because you have to wait until the element you want to focus has been loaded to the DOM. But if you wait to much, then the user could have focused another input, and your change of focus will be annoying.
