paramsAsHash: Boolean
Only used when using directFn. Send parameters as a collection of named arguments (defaults to false). Providing a paramOrder nullifies this configuration.

requestData : function(node, callback, scope){
    if(this.fireEvent("beforeload", this, node, callback) !== false){
        if(this.directFn){
            var args = this.getParams(node);
            args.push(this.processDirectResponse.createDelegate(this, [{callback: callback, node: node, scope: scope}], true));
            this.directFn.apply(window, args);
        }
