Bowser
|
|
------
|
|
A Browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.
|
|
|
|
So... it works like this:
|
|
|
|
``` js
|
|
if (bowser.msie && bowser.version <= 6) {
|
|
alert('Hello China');
|
|
}
|
|
```
|
|
|
|
Detected Browsers
|
|
-----
|
|
|
|
* msie
|
|
* safari[webkit]
|
|
* chrome[webkit]
|
|
* firefox[gecko]
|
|
* opera
|
|
|
|
Notes
|
|
----
|
|
Safari, Chrome, and Firefox will report that they have webkit|gecko engines
|
|
|
|
``` js
|
|
if (bowser.webkit) {
|
|
// do stuff with safari & chrome
|
|
}
|
|
```
|
|
|
|
Ender installation
|
|
-----
|
|
If you don't already have [Ender](http://ender.no.de) (an npm package) install it now (and don't look back)
|
|
|
|
$ npm install ender
|
|
|
|
then add bowser to your module collection
|
|
|
|
$ ender add bowser
|
|
|
|
use it like this:
|
|
|
|
``` js
|
|
if ($.browser.chrome) {
|
|
alert('Hello Silicon Valley');
|
|
}
|
|
```
|
|
|
|
Graded Browser Support
|
|
---------
|
|
One useful feature of Bowser is that aside from checking one browser from another -- it will keep up to date with [Yahoo's Graded Browser Support](http://developer.yahoo.com/yui/articles/gbs/) chart, giving you access to each grade on the bowser object
|
|
|
|
``` js
|
|
if (bowser.a) {
|
|
// support full feature set
|
|
}
|
|
else if (bowser.c) {
|
|
// serve degraded version
|
|
}
|
|
else {
|
|
// unsupported (bowser.x)
|
|
}
|
|
```
|
|
|
|
Building
|
|
--------
|
|
|
|
If you'd like to contribute a change to bowser, modify the files in src/, then run the following (you'll need node + npm installed):
|
|
|
|
$ npm install
|
|
$ make
|
|
|
|
|
|
Testing
|
|
-------
|
|
We started a list `src/useragents.js` with example user agents and their expected bowser object.
|
|
|
|
Whenever you add support for new browsers or notice a bug / mismatch, please update the list and
|
|
check if all tests are still passing.
|
|
|
|
To run the test call `$ make test`
