JS判断浏览器

var browser={    versions:function(){            var u = navigator.userAgent, app = navigator.appVersion;            return {
   //移动终端浏览器版本信息                 trident: u.indexOf('Trident') > -1, //IE内核                presto: u.indexOf('Presto') > -1, //opera内核                webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核                gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核                mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端                ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端                android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或者uc浏览器                iPhone: u.indexOf('iPhone') > -1 , //是否为iPhone或者QQHD浏览器                iPad: u.indexOf('iPad') > -1, //是否iPad                  webApp: u.indexOf('Safari') == -1, //是否web应该程序，没有头部与底部                weixin: u.indexOf('MicroMessenger') > -1, //是否微信                 qq: u.match(/\sQQ/i) == " qq" //是否QQ            };         }(),         language:(navigator.browserLanguage || navigator.language).toLowerCase()    }

JS查询URL的search

function getQueryString(name) {        var reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i');        var r = window.location.search.substr(1).match(reg);        if (r != null) {            return unescape(r[2]);        }        return null;    }

JS URL的search转化为对象

function paramsObj() {        var search = location.search.substring(1),            obj = '';        if (search) {            obj = JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')        }        return obj;    }

 

function  analyseUrl( ){
    　　var url = location.href;    var obj = {};    if(url.indexOf('?') != -1){        var opt = url.split('?');                var str = opt[1];        arr = str.split('&');        var arrLast = arr[arr.length - 1];        if(arrLast.indexOf('#') != -1){            arr[arr.length - 1] = arrLast.substr(0, arrLast.indexOf('#'));        }        for(var i = 0; i < arr.length; ++i){            var para = arr[i].split('=');            obj[para[0]] = para[1];        }    }    return obj;}
