How to identify dolphin lite browser from javascript

问题

I have a widget which unfortunately doesn't display well on Dolphin lite browsers since position:fixed is not supported.

The user agent string I see is :

Mozilla/5.0 (Linux; U; Android 2.2.1; iw-il; X10i TripNMiUI Build/NI1063) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

How can I use this to identify dolphin browsers (any version) ? Or is there another way to do that?

Alternatively I found a code that checks for position=fixed support but it looks risky to incorporate in production. Is there is a safe way to do this that could solve to my problem?
