Objects or Scripts

Problem: Most mobile devices don’t support embedded objects or scripts and it’s usually not possible for users to install plug-ins to workaround this. Design content with this in mind. Even where a device does support scripting, steer clear of using it unless you can’t find another way to reach your objectives. Use of client-side scripting increases power consumption and drains the battery faster.

Solution: Skip scripts and embedded objects.

Discussion: While many modern browsers support scripting it may be disabled so you should ensure that your page works well without it.
If you must rely on either scripting or embedded objects, apply an advanced device detection strategy, routing devices with better scripting support to pages specifically tailored to support those devices.
