Demystifying WMLScript (part 1)
Client-side scripting comes to WML-enabled devices.

| Technology Marches Onward |

If you think back a little, you'll remember how the Web first began with HTML, static pages on which image maps and animated GIFs were considered cutting-edge. And you'll remember how Web users clamoured for more interactivity on those static pages, interactivity that became simpler once dynamic HTML and Javascript became standard accessories for your Internet browser.

If you look at the wireless Web today, you'll see a similar transition taking place. Static WML pages are slowly becoming as passe as static HTML pages, and users are looking for more interactivity...preferably with a minimal performance hit. WMLScript promises to bring Javascript-like capabilities and power to WML developers, by providing them with a powerful tool for client-side scripting.

WMLScript is based on ECMAScript, which is the standard for all client-side scripting languages. The ECMAScript standard, created by the European Computer Manufacturers Association (ECMA), is adhered to by most current client-side languages in use on the Web, including JavaScript and VBScript. Since WMLScript is currently the only scripting language that can work on WAP-enabled wireless devices, it has been developed keeping the ECMA standards in mind; despite this, however, it still does not meet all the standards laid down by ECMA due to inherent constraints in the medium.
