altintx / fix-bootstrap-4-dropdown-menus.js
Last active April 18, 2017 15:50
In bootstrap 4 alpha 6 dropdown menus don't open. These jQuery listeners fix it.
$(document).on('click', ".dropdown [data-toggle=dropdown]", function(eve){
const button = $(eve.target),
dropdownContainer = button.parent(".dropdown");
const closeMenu = function() {
dropdownContainer.removeClass("show");
$(document).unbind("click", docListener);
$("a", dropdownContainer).unbind("click", menuClickListener);
};
function flatten(input) { console.log(input);
var _flatten = (input, output) => {
console.debug("flattening %o", input);
return input.reduce((output, item) => {
if (typeof item == "object" && item instanceof Array) {
console.debug("flattening nested array %o", item);
return _flatten(item, output);
} else {
output.push(item);
return output;

altintx / Card.js
Created October 3, 2012 22:09
In a Sencha Touch navigation view, have you ever wanted different buttons in the titlebar portion of individual cards? With the activeitemchange listener down below, each card can declare their own navbar buttons (or even other types of widgets) and they'll be automatically appear when that particular card is active.
Ext.define("App.view.default.Card", {
extend: "Ext.List",
alias: "widget.defaultcard",
navigationBarItems: [
{
text: "Add",
align: "right",
eventName: "add"
}
