Question

ok so i built a dynamic content swapping system using mootools for my website and I’m having trouble with one aspect about it. When it pulls the new content off the server it also gets a snippet of code which is to be executed by the Type Function

    setContent: function(content) {
    var self = this;
    window.history.pushState({x: 0}, "x", content[0].toLowerCase());
    var mainField = $('meat');
    mainField.set('html', content[1]);
    if(content[2] != false) {
        var functionn = Function(content[2]);
        functionn();
    }
},

Now in this situation im trying to execute a method in the class:

addLink: function(item) {
    var self = this;
    var object = $(item);
    self.menus.include(item);
    object.addEvent('click', function(event) {
        event.stop();
    });
},

by sending this to the set content method to be executed:

self.addLink('#order');

now when I try it out i get this error:

Uncaught TypeError: Object [object Window] has no method 'addLink'

I guess self refers to window rather than to your class, see the example at http://mootools.net/docs/core/Types/Function#Function:bind. Use bind() to bind this to your class and then use this in your server reply.

if(content[2] != false) {
    var functionn = Function(content[2]);
    var functionn_bound = functionn.bind(this);
    functionn_bound();
}
