Custom skinned data validation alerts can be associated with forms and bound to input controls or other HTML elements. These window alerts popup when a particular event is triggered (E.g. Bad input resides in a text box on a form). Alphanumeric data entry into a strict numeric text input control may trigger a window alert. A mismatched amount in a calculation may trigger a window alert as well. Other examples include alerts that aren't modal and unlike browser's built in alert windows that are always modal (i.e. require input taking control of your browser window). This alert script can be used for a more user-friendly, completely customizable and appealing form bound message box.
