NetFront runs programs called "scripts" on Webpage, which enables Webpages to display a variety of styles and functions such as animating content. NetFront supports JavaScript as a script function. Set whether or not to run JavaScript in the "NetFront Settings" (1/4 [Display/Advanced]) page.

Security and JavaScript
JavaScript starts automatically when you turned it on, occasionally causing a lower security level. Whenever you need a high security, turn it off.

JavaScript That Cannot Be Executed
NetFront supports JavaScript, but cannot handle certain JavaScript functions due to specifications of CLIÉ handheld and Palm OS.
