A few weeks ago I shared a trick for getting the first and last focusable element in the DOM.
var focusable = document.querySelectorAll('button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'); var firstFocusable = focusable; var lastFocusable = focusable[focusable.length - 1];
Reader Csaba Varszegi asked (shared with permission):
A small question: what is the reason that you are using
a? Because if an anchor has no
href, it is not focusable? Or because you want other elements with an
href(valid?) to be selected? Or both?
Simply put, links are only focusable if they have an
href. Otherwise, tabbing through the DOM just skips right over them.
