[removed] sharing data between tabs [closed]

Answer 1

If the first tab opens the second tab automagically, you can do something like this:

First tab:

//open the first tab
var child_window = window.open( ...params... );

Second tab:

// get reference to first tab
var parent_window = window.opener;

Then, you can call functions and do all sorts of stuff between tabs:

// copy var from child window
var var_from_child = child_window.some_var;

// call function in child window
child_window.do_something( 'with', 'these', 'params' )

// copy var from parent window
var var_from_parent = parent_window.some_var;

// call function in child window
parent_window.do_something( 'with', 'these', 'params' )
