There's a period of time that I changed my web programming method. I develop my functions as web methods in some Web Services, then I call them in my website's UI using javascript. My question is why do we use web services? I think it's better to write these functions in the code behind of original page and call them with javascript. Isn't it better?
Webservices can be called from any platform, but the code in the behind of web forms can not.
