js判断是否安装某app，怎么实现,第1张

1，判断是否安装某app

这个问题只能是APP才有可能做到，代码与网页端无关

2，JS调用Andorid/IOS的接口

这个问题需要两端配合，移动APP端书写调用接口及调用规则，JS按照语法调用即可

Js判断客户端是否为PC还是手持移动设备

方法一

function IsPC(){

var userAgentInfo = navigator.userAgent

var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod")

var flag = true

for (var v = 0v

if(userAgentInfo.indexOf(Agents[v]) >0) { flag = falsebreak}

}

return flag

}

if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) {

//alert(navigator.userAgent)

window.location.href ="iPhone.html"

} else if (/(Android)/i.test(navigator.userAgent)) {

//alert(navigator.userAgent)

window.location.href ="Android.html"

} else {

window.location.href ="pc.html"

}

方法二

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()

}

if(browser.versions.mobile || browser.versions.ios || browser.versions.android ||

browser.versions.iPhone || browser.versions.iPad){

window.location = "http://m.zhaizhainv.com"

}

方法三：摘自im- qq

var os = function() {

var ua = navigator.userAgent,

isWindowsPhone = /(?:Windows Phone)/.test(ua),

isSymbian = /(?:SymbianOS)/.test(ua) || isWindowsPhone,

isAndroid = /(?:Android)/.test(ua),

isFireFox = /(?:Firefox)/.test(ua),

isChrome = /(?:Chrome|CriOS)/.test(ua),

isTablet = /(?:iPad|PlayBook)/.test(ua) || (isAndroid &&!/(?:Mobile)/.test(ua)) || (isFireFox &&/(?:Tablet)/.test(ua)),

isPhone = /(?:iPhone)/.test(ua) &&!isTablet,

isPc = !isPhone &&!isAndroid &&!isSymbian

return {

isTablet: isTablet,

isPhone: isPhone,

isAndroid : isAndroid,

isPc : isPc

}

}()

使用方法

if(os.isAndroid || os.isPhone){

alert("-----")

}

方法四：

if(/AppleWebKit.*mobile/i.test(navigator.userAgent) || (/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){

if(window.location.href.indexOf("?mobile")<0){

try{

if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){

window.location.href="手机页面"

}elseif(/iPad/i.test(navigator.userAgent)){

window.location.href="平板页面"

}else{

window.location.href="其他移动端页面"

}

}catch(e){}

}

方法五

//平台、设备和操作系统

varsystem ={

win:false,

mac:false,

xll:false

}

//检测平台

varp = navigator.platform

system.win = p.indexOf("Win") ==0

system.mac = p.indexOf("Mac") ==0

system.x11 = (p =="X11") || (p.indexOf("Linux") ==0)

//跳转语句，如果是手机访问就自动跳转到caibaojian.com页面

if(system.win||system.mac||system.xll){

}else{

window.location.href="http://caibaojian.com"

}

方法六

functionis_mobile(){

varu = navigator.userAgent

if(null== u) {

returntrue

}

varresult = regex_match.exec(u)

if(null== result) {

returnfalse

}else{

returntrue

}

if(is_mobile()) {

document.location.href='http://caibaojian.com'//修改http://caibaojian.com为你所需跳转目标页地址

}

方法7 百度webapp版

(function(){

varres = GetRequest()

varpar = res['index']

if(par!='gfan'){

varua=navigator.userAgent.toLowerCase()

varcontains=function(a, b){

if(a.indexOf(b)!=-1){returntrue}

}

//将下面的http://caibaojian.com改成你的wap手机版页面地址如我的 http://caibaojian.com

vartoMobileVertion =function(){

window.location.href ='http://caibaojian.com/'

}

if(contains(ua,"ipad")||(contains(ua,"rv:1.2.3.4"))||(contains(ua,"0.0.0.0"))||(contains(ua,"8.0.552.237"))){returnfalse}

if((contains(ua,"android") &&contains(ua,"mobile"))||(contains(ua,"android") &&contains(ua,"mozilla")) ||(contains(ua,"android") &&contains(ua,"opera"))

||contains(ua,"ucweb7")||contains(ua,"iphone")){toMobileVertion()}

}

})()

functionGetRequest(){

varurl = location.search//获取url中"?"符后的字串

vartheRequest =newObject()

if(url.indexOf("?") !=-1) {

varstr = url.substr(1)

strs = str.split("&")

for(vari =0i <strs.lengthi ++) {

theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1])

}
