Question

When using jQuery methods within an object function (ie – .each()), the “this” variable is then referencing the object being iterated over. How can I access the Object’s functions without “this”? I realize that’s a bit confusing, so:

test.prototype.init = function(node) {
    node.children().each(function() {
        //call test.anotherFunction() here
        //Would normally call this.anotherFunction(), 
        //  but "this" refers to the current child.
    });
}
test.prototype.anotherFunction = function() {
    //whatever
}

Help?

Save a copy of this into a local variable (named self in this example, but you can name it anything you want) and use the saved copy in your embedded function:

test.prototype.init = function(node) {
    var self = this;
    node.children().each(function() {
        // use self here to reference the host object
    });
}
test.prototype.anotherFunction = function() {
    //whatever
}
