JS to determine whether the client is iOS or Android mobile terminals such as the method of _javascript skills

principle of judgment:

JavaScript is the primary language for front-end development, and we can write JavaScript programs to determine the type and version of the browser. JavaScript can determine browser types in general there are two ways, one is based on a variety of browser-specific properties to distinguish, the other is by analyzing the browser's useragent properties to judge. In many cases, after the value is judged by the browser type, it is also necessary to judge the browser version to handle the compatibility issue, and to judge the browser version is generally only through the analysis of the browser useragent to know.

Browser Type

⑴ Browser-specific properties
⑵ according to UserAgent
Browser version

<script type= "Text/javascript" >
var browser={
Versions:function () {
var u = navigator.useragent, app = Navigator.appversion;
return {//Mobile terminal browser version information
Trident:u.indexof (' Trident ') >-1,//ie kernel
Presto:u.indexof (' presto ') >-1,//opera kernel
Webkit:u.indexof (' AppleWebKit ') >-1,//Apple, Google kernel
Gecko:u.indexof (' Gecko ') >-1 && u.indexof (' khtml ') = = 1,//Firefox kernel

}(),

Document.writeln ("Whether for Mobile Terminal:" +browser.versions.mobile);
Document.writeln ("iOS terminal:" +browser.versions.ios);
Document.writeln ("Android Terminal:" +browser.versions.android);
Document.writeln ("Whether for IPhone:" +browser.versions.iphone);
Document.writeln ("Whether the IPad:" +browser.versions.ipad);
Document.writeln (navigator.useragent);
