Determine the browser type and browser

When making the front-end, you need to determine the user's browser type:

A small piece of code

Var mobileAgent = new Array ("iphone", "ipod", "ipad", "android", "mobile", "blackberry", "webos", "incognito ", "webmate", "bada", "nokia", "lg", "ucweb", "skyfire ");
Var browser = navigator. userAgent. toLowerCase ();
For (var I = 0; I <mobileAgent. length; I ++ ){
If (browser. indexOf (mobileAgent [I])! =-1 ){
Flag = true;
Break
}
};


Perform operations according to the flag after the judgment is completed...


How does js determine the browser type?

<Script type = "text/javascript">

Function isIE (){
Return navigator. appName. indexOf ("Microsoft Internet Explorer ")! =-1 & document. all;
}

Function isIE6 (){
Return navigator. userAgent. split (";") [1]. toLowerCase (). indexOf ("msie 6.0") = "-1 ″? False: true;
}

Function isIE7 (){
Return navigator. userAgent. split (";") [1]. toLowerCase (). indexOf ("msie 7.0") = "-1 ″? False: true;
}

Function isIE8 (){
Return navigator. userAgent. split (";") [1]. toLowerCase (). indexOf ("msie 8.0") = "-1 ″? False: true;
}

Function isNN (){
Return navigator. userAgent. indexOf ("Netscape ")! =-1;
}

Function isOpera (){
Return navigator. appName. indexOf ("Opera ")! =-1;
}

Function isFF (){
Return navigator. userAgent. indexOf ("Firefox ")! =-1;
}

Function isChrome (){
Return navigator. userAgent. indexOf ("Chrome")>-1;
}
</Script>
