When a user checks the radio button on the webpage, the Form validation controls on the script page calls the JQuery validate function from the library. These validate functions, then direct the output based on the business rules specified. The Form validation controls are available as plugin when we use the JQuery script. These are quite simple and ready to use plugins. Download the JQuery plugin pack and get the validate file on to the web server. There may be a need to tweak the script code to include any user controls required. The user controls are passed on to these validate file when the user enters the input. In competition, Dreamweaver 4.0 has also launched equivalent tools for tooltip, dropdown in addition to Form validation controls.
