This will give you an idea of what object is constructed after the data type string have been parsed.

Alternatively, to convert to local time is pretty easy: use // Your default date object var starttime = new Date(); // Get the iso time (GMT 0 == UTC 0) var isotime = new Date((new Date(starttime))ISOString() ); // get Time() is the unix time value, in milliseconds.

// get Timezone Offset() is UTC time and local time in minutes.

Even different versions of Netscape or Internet Explorer support different Java Script features.

Example 7-7 shows how the browser application name and version can be detected with both Java Script and PHP.

You can validate the user input at the time of form submission or on on Blur event. Month and Date can be either be single digit or multiple digit.

It is very important to validate the data supplied by the user through a form before you process it. In the following examples, a Java Script function is used to check a valid date format against a regular expression.In this section, we briefly introduce the Java Script scripting language as a client-side method for validation and other simple tasks.Java Script isn't a fully fledged programming language like PHP: it can't connect to databases, it's limited as to which system resources it can interact with, and it can't do most tasks a web database application requires.Pointers to books and other resources on Java Script are included in Appendix E. This book is focused on thin clients, where the majority of the application logic resides in the middle tier.We recommend that Java Script be kept simple: complex tasks should be left to the middle-tier scripts, and interfaces should still function correctly even if Java Script is faulty or disabled.Another common approach in Java Script-intensive web database applications is to write two sites: one that uses Internet Explorer Java Script and another that uses Netscape Navigator Java Script.
