How to use

This plugin provides an EventStack Class.

var EscapeStack = new EventStack; // The default options pop the stack when the user presses 'esc'

EscapeStack.push(closeMyWidget); // MyWidget will be closed when the user presses 'esc'

// Now if MyWidget spawns another widget on top of MyWidget you can push the close handler too
MyWidget.openAnotherWidget = function(){
    EscapeStack.push(closeMyOtherWidget);

    openAnotherWidget();
};

// Now pressing the 'esc'-Button once closes 'AnotherWidget', pressing it again closes 'MyWidget'

If your widget has other ways of closing it (like an 'X'-Button) you should remove the close-handler from the stack.

EscapeStack.erase(closeMyWidget);

Build

Build via Packager, requires MooTools Core and MooTools Class-Extras to be registered to Packager already

packager register /path/to/event-stack
packager build EventStack/* > event-stack.js

To build this plugin without external dependencies use

packager build EventStack/* +use-only EventStack > event-stack.js

Demo

See Demos/index.html

Options

• event - (defaults to keyup) The event to be used
• condition - Function to be used to determine whether to pop the stack. Defaults to pressing the ESC-Button.

Plugins

An OuterClick-stack can be used to close widgets if the user clicks outside of them.

Create an OuterClickStack:

var OuterClickStack = new EventStack.OuterClick;

Usage:

OuterClickStack.push(fn, element); // Note the second argument, it allows you to associate any value with the pushed stack function

Notes

It's not a real stack :)
