How to provide namespaces in JavaScript with instanced objects

Question

I\'ve got a JavaScript \"object\", built this way:

function foo()
{
    this.length = 0;
}

foo.prototype.getLength = function()
{
    return this.length;
}

...         


        

Answer 1

Both answers were very helpful! Here's what I ended up with:

if( typeof( rpNameSpace ) == "undefined" ) rpNameSpace = {};

rpNameSpace.foo = function() {
    this.length = 613;
}
rpNameSpace.foo.prototype.getLength = function() {
    return this.length * 2;
}

Then, to use the resulting "namespaced" object:

var x = new rpNameSpace.foo()

display( x.getLength() );
