The browser is not just a computer browser code collation-related skills

The judgment includes not only computer browsers, but also Android, iOS mobile phones and tablets, gaming systems

Copy Code code as follows:

var client = function () {
Rendering engine
var engine ={
ie:0,
gecko:0,
webkit:0,
khtml:0,
opera:0,
Ver:null
};
Browser
var browser = {
ie:0,
firefox:0,
safari:0,
konq:0,
opera:0,
chrome:0,
Ver:null
};
var system ={
Win:false,
Max:false,
X11:false,
Mobile devices
Iphone:false,
Ipod:false,
Ipad:false,
Ios:false,
Android:false,
Nokian:false,
Winmoble:false,
Game system
Wii:false,
Ps:false
};
var ua =navigator.useragent;
Opera 9 After the emergence of two kinds of string proxy way one way is to identify themselves to another browser another way is to mark themselves as Firefox or IE
In the latter case, the user agent string is actually the same as that of the other browsers--neither opera's words nor opera's version information
So the browser starts with opera.
if (Winddow.opera) {
Engine.ver = Browser.ver = Window.opera.version ();
Egine.opera = Browser.opera = parsefloat (engine.ver);
The second detection WebKit is due to WebKit's user agent Gecko "and" HTMKL "strings so if you detect them first, they all have the wrong conclusion.
}else if (/applewebkit\/(\s+)/.test (UA)) {
Engin.ver = regexp["$"];
Engine.webkit = parsefloat (engine.ver);
Sure it's Chrome or safari?
if (/chrome\/(\s+)/.test (UA) {
Browser.ver = regexp["$"];
Browser.chrome = parsefloat (brower.ver);
}else if (/version\/(+\s)/.test (UA)) {//safari 3.0 adds the Version property
Browser.ver = regexp["$"];
Browser.safari = parsefloat (brower.ver);
}else{

if (engine.webkit<100) {
Safariversion = 1;
}else if (engine.ver<312) {

}

engine.khtml = parsefloat (engine.ver);
}else if (/rv: ([^\)]+\) gocko\/\d{8}/.test (UA)) {
Engine.ver = regexp["$"];

Sure it's not Firefox.

detecting browsers

detecting iOS versions
//

System.ios = parsefloat (Rexexp.$1.replace ("_", "."));
}else {

}
}
Check an Android version
//
if (/android (\d+/_\d+)/.test (UA)) {
System.andriod = parsefloat (regexp.$1);
}
Game system
System.wii = Us.indexof ("Wii") >-1;
system.ps =/playstation/i.test (UA);
