wizard04wsu / createFunctionWithTimeout.js
Last active March 16, 2016 19:14
Adds a timeout to a callback so that if the function isn't called within the timeout, the callback will be run anyway.
function createFunctionWithTimeout(callback, opt_timeout){
var called, timer;
//if the function *isn't* called within the timeout, execute callback() anyway
timer = setTimeout(function (){
called = true;
callback();
}, opt_timeout || 1000);
//if the function *is* called within the timeout, cancel the timer and execute callback()

Last active September 10, 2017 20:21
Clones an event object. You can optionally pass new initialization values to override the ones from the cloned event object.
function cloneEventObj(eventObj, overrides){
var p, eventInit = {}, clone;
overrides = overrides || {};
for(p in eventObj){
eventInit[p] = eventObj[p];
}
for(p in overrides){
eventInit[p] = overrides[p];
}

Last active July 1, 2020 17:58
HTML/JavaScript menu bar that can be navigated with the mouse and keyboard. Tested with the NVDA screen reader; using ARIA role="menubar" reduces noise and automatically enters focus mode. *** requires https://gist.github.com/wizard04wsu/3ec34604d7538303e9f0 ***
ul.menubar, ul.menubar ul {
list-style-type:none;
}
ul.menubar > li {
display:inline-block;
vertical-align:top;
border:1px solid red;
}
ul.menubar ul {
