如何根据浏览器（即Blackberry 8300）在网页上强制禁用JavaScript？

Question

I have some JavaScript that doesn't work correctly on the Blackberry 8300 . The page renders differently if JavaScript is disabled. However, I'd like to be able to have the page render the "JavaScript disabled" version also if the user is on a Blackberry 8300 or on a media of type "handheld".

Is there some way I can do this? Or some check I can do? Can I detect whether the media is "handheld" and if so, to render the non-JavaScript version of the page?

For example, some if case where if media==handheld, then .. SOME HTML HERE ..

Or is there some way to "degrade" a browser to an older version?

Answer 1

In pure HTML you have the <noscript> tag. Any other form of conditional output will have to be done on the server in another language of your choice.

Answer 2

You can check User Agent in the HTML header.

Blackberry's browser identifies itself as something like: BlackBerry8700/4.1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 . Just check whether "BlackBerry" is a substring.

There is a incomplete List of user agents for mobile phones .
