Manage commnunication between browser tabs.
this js lib can perform several actions on browser tabs like :
    - (*new) varset  - set a stringifiable object on tabs
    - (*new) varsync - synchro a object previously set with varset on an other tab
    - (*new) prepend node
    - (*new) synchro node attributes
    - define custom before and after command functions
    - search and kill zombies tabs (enable onload by default)
    - append/rewrite/synchro node on all (other) tabs or a specific tab (and possibly on specific frame context) eventually with callback.
    - reload all tabs or a specific tab with specified url or tab 's current url
    - perform your custom actions on all tabs or specific tab

require

html5 localStorage svan (pluie.org small vanilla jquery-like lib)

Initialize

$(document).ready(function() {
    // $bt.zkillonload = false // disable zombkill cmd at statup
    $bt.init(optionalCallback);
}

Internal Commands

// append data on node to other browser tabs
$bt.append('#test', "<b>it's cool to append</b>");

// rewrite content on node to other browser tabs
$bt.html('#test', "<b>it's cool to rewrite</b>");

// append content to specific browser tab
$bt.append('#test', "<b>it's cool to rewrite</b>", null, null, '1449974562012');

// rewrite content to specified browser tab with callback
// callback must be define before command with method $bt.setCallback('callbackname', callback);
$bt.html('#test', "<b>it's cool to rewrite</b>", null, 'callbackname', '1449974562012');

// append content to specified browser tab on specific frame
$bt.append('#test', "<b>it's cool to rewrite</b>", 'frameName', null, '1449974562012');

// perform a node synchro to other browser tabs
$bt.sync('#test');

// perform a node synchro to specified browser tab on specific frame with callback
$bt.sync('#test', 'frameName', 'callbackname', '1449974562012');

// perform a node attr synchro to all browser tab
$bt.attr('#test', ['class', 'title']);

// perform a varset to all tabs
$bt.varset('myVar', { toto : tutu : { tata : "titi" }});

// perform a varsync from specific tab (for example after calling tab will reload)
$bt.varsync('myVar', '1449974562012');

// reload other browser tabs
$bt.reload();

// reload specific browser tab to specific url
$bt.reload(window.location.path+"?reloaded=1", '1449974562012');

// search and kill zombies tabs
$bt.zombkill(callback, timeout);

// get browser tab list
$bt.list;

// current browser tab id
$bt.id;

Custom Commands

// define a new custom cmd
$bt.CMD_CUSTOM = "customCmd";
// treat custom command to other browser tabs
$bt.on = function(cmd) {
    switch (cmd.name) {
        case $bt.CMD_CUSTOM :
            // do stuff
            $bt.log("custom command `'+cmd.name+'` with `'+cmd.customKey+'`');
        break;
    }
}

// it's also possible to define a before and after function :
$bt.before = function(cmd) {
    $bt.log("i'm fired before every command");
}

$bt.after = function(cmd) {
    $bt.log("i'm fired after every command");
}

// send a custom command to other browser tabs
$bt.send({ name : $bt.CMD_CUSTOM, customKey : 'customValue' });

Bonus

// alias localStorage : clear|rem|get|set
$l
// alias json : str|obj
$j

Demo

on chromium/chrome browser make sure to test on a web server (not directly file://)
