js判断页面是从pc,ipad,phone 打开的
function IsPC() { var userAgentInfo = navigator.userAgent; var Agents = [ "Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod" ]; for (var v = 0; v < Agents.length; v++) { if (userAgentInfo.indexOf(Agents[v]) > 0) { return Agents[v]; } } }; var shebei = IsPC(); console.log(shebei)
