This isn't possible, unfortunately. HTTrack *does* 
understand simple javascript functions like

window.open('../accommodate/accommodate.asp?id=12',...

BUT not complex expressions, with embedded parameters!

The is no spider which comes with this feature, 
however - as analyzing the code itself is really hard.
The only trick would be to recognize javascript 
generated by several composers like dreamweaver, 
frontpage and so on.. but this won't be a solution
