Claim One:
1. A method for analyzing one or more scripts contained within a document to determine if the scripts perform one or more predefined functions, the method comprising the steps of: identifying, from the one or more scripts, one or more scripts relevant to the one or more predefined functions; interpreting the one or more relevant scripts; intercepting an external function call from the one or more relevant scripts while the one or more relevant scripts are being interpreted, the external function call directed to a document object model of the document; providing a generic response, independent of the document object model, to the external function call; requesting a browser to construct the document object model if the generic response did not enable further operation of the relevant scripts; and providing a specific response, obtained with reference to the constructed document object model, to the external function call if the browser was requested to construct the document object model.
