Browser types and Version Detection Methods provided by PPK

A common but overestimated Javascript function is browser detection. Sometimes, you may want to give a description or load a page to prompt users to avoid using browsers such as Safari.

Usage:

Browser name: BrowserDetect. browser
Browser version: BrowserDetect. version
OS name: BrowserDetect. OS

 

Var BrowserDetect = {
Init: function (){
This. browser = this. searchString (this. databrown) | "An unknown browser ";
This. version = this. searchVersion (navigator. userAgent)
| This. searchVersion (navigator. appVersion)
| "An unknown version ";
This. OS = this. searchString (this. dataOS) | "an unknown OS ";
},
SearchString: function (data ){
For (var I = 0; I <data. length; I ++ ){
Var dataString = data [I]. string;
Var dataProp = data [I]. prop;
This. versionSearchString = data [I]. versionSearch | data [I]. identity;
If (dataString ){
If (dataString. indexOf (data [I]. subString )! =-1)
Return data [I]. identity;
}
Else if (dataProp)
Return data [I]. identity;
}
},
SearchVersion: function (dataString ){
Var index = dataString. indexOf (this. versionSearchString );
If (index =-1) return;
Return parseFloat (dataString. substring (index + this. versionSearchString. length + 1 ));
},
