Is the web mobile development still relevant in IFS Applications8?

The following is a small list of limited capabilities on mobile web browsers (e.g. Pocket IE).

HTML 3.2 Compliant

• Lightweight HTML
• Framesets as per HTML 4.0 compliment and borders always visible.
• supports background images.
• Little or No DHTML support on most browsers.
• Limited CSS support.
• No support for animated gif images

JavaScript 1.1 compliant

• HTML 3.2-based object model, not IE4 object model
• Supports scripting against FORM elements
• Supports scripting against XML object model
• No support for Dynamic frameset creation
• No support for Dynamic script generation
• No support for window.open (popup windows)

XML Object Model

• Same XML components as IE5
• Markup and transfer of data as XML (aka: AJAX)
• Use of XSL to transform XML to HTML

Security

• SSL
• 64-bit certificates
• 128-bit encryption (add-on)

Active X support (for Pocket IE versions)

• Straightforward – just like the desktop
• COM component accessed from <OBJECT> tag
• Script can call ActiveX components, but not vice-versa
• Must be installed on device directly
