    Components.utils.getGlobalForObject

    This method is used to determine the global object with which an object is associated. This is the global object in place at the time the object was created, which is to say the global object used when executing the script that created the object.

    Syntax

    var global = Components.utils.getGlobalForObject(obj);
    

    Parameters

    obj
    an object whose corresponding global object is to be retrieved; non-optional, must be object-valued

    Example

    var obj = {};
    function foo() { }
    var global = this;
    
    var g1 = Components.utils.getGlobalForObject(foo);
    var g2 = Components.utils.getGlobalForObject(obj);
    // g1 === global, g2 === global, g1 === g2
    
    // In a script in another window
    var global2 = this;
    function bar() { }
    var obj2 = {};
    
    // Then, assuming bar refers to the function defined in that other window:
    var o1 = Components.utils.getGlobalForObject(bar);
    var o2 = Components.utils.getGlobalForObject(obj2);
    // o1 === global2, o2 === global2
