常用js 代码

1.手机类型判断

var BrowserInfo = {

userAgent: navigator.userAgent.toLowerCase()

isAndroid: Boolean(navigator.userAgent.match(/android/ig)),

isIphone: Boolean(navigator.userAgent.match(/iphone|ipod/ig)),

isIpad: Boolean(navigator.userAgent.match(/ipad/ig)),

isWeixin: Boolean(navigator.userAgent.match(/MicroMessenger/ig)),

}

2.获取url参数

function GetQueryStringRegExp(name,url) {

var reg = new RegExp("(^|\?|&)" + name + "=([^&]*)(\s|&|$)", "i");

if (reg.test(url)) return decodeURIComponent(RegExp.$2.replace(/+/g, " ")); return "";

}
