Sample

The default namespace is "fn",you can use the function as this example

var ua = fn.ua()
//return an object whihc contains some user agent info
{
    isPC:false,         
    isMobile:true,      
    platform:'iphone',  //pc | iphone | ipad ..
    browser:'wx',       //browser name
    version:6           //browser version
}

When you use it as a single file,if the "fn" is existed,or you just wanna change another name,you can do like this:

var ___ = fn.conflict()
__.ua()
