由于目前需要判断浏览器类型及终端来源，因此做了一下的总结：
判断浏览器类型：
<!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="utf-8"> <title>判断浏览器类型</title> </head> <body> </body> <script language="JavaScript"> <!-- function getBrowserType() { var agent = navigator.userAgent.toLowerCase() ; var browserType = ''; if(agent.indexOf("msie")>0) { browserType = 'ie'; } if(agent.indexOf("firefox")>0){ browserType = 'firefox'; } if(agent.indexOf("safari") > 0 && agent.indexOf("chrome") < 0) { browserType = 'safari'; } if(agent.indexOf("chrome")>0){ browserType = 'chrome'; } if(agent.indexOf("opera")>0){ browserType = 'opera'; } return browserType; } alert("您的浏览器类型为:"+getBrowserType()); --> </script> </html>
判断终端来源：
function getTerminal(){ var Type = 'pc';//默认为pc端，可取两值：pc,MT(移动端) var terminal = '';//终端标识，值可取iPhone,iPod,Android,iPad if( (navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/Android/i)) || (navigator.userAgent.match(/iPad/i)) ) { Type = 'MT'; } if(navigator.userAgent.match(/iPhone/i)){ terminal = 'iPhone'; } if(navigator.userAgent.match(/iPod/i)){ terminal = 'iPod'; } if(navigator.userAgent.match(/Android/i)){ terminal = 'Android'; } if(navigator.userAgent.match(/iPad/i)){ terminal = 'iPad' } return {"Type":Type,"terminal":terminal}; }
