1、判断终端是安卓端还是IOS端

    varu =navigator.userAgent;

    varisAndroid = u.indexOf('Android') > -1|| u.indexOf('Adr') > -1;//android终端

    varisiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/);//ios终端

2、

2-1、ios端回调代码（固定的）

if(isiOS){

/*这段代码是固定的，必须要放到js中*/

functionsetupWebViewJavascriptBridge(callback) {

if(window.WebViewJavascriptBridge) {returncallback(WebViewJavascriptBridge);}

if(window.WVJBCallbacks) {returnwindow.WVJBCallbacks.push(callback);}

window.WVJBCallbacks= [callback];

varWVJBIframe =document.createElement('iframe');

WVJBIframe.style.display='none';

WVJBIframe.src='wvjbscheme://__BRIDGE_LOADED__';

document.documentElement.appendChild(WVJBIframe);

setTimeout(function() {document.documentElement.removeChild(WVJBIframe) },0)

}

/*与OC交互的所有JS方法都要放在此处注册，才能调用通过JS调用OC或者让OC调用这里的JS*/

setupWebViewJavascriptBridge(function(bridge) {

document.getElementById('enjoy').onclick =function() {

bridge.callHandler('game',{'data':kuang.innerHTML},functionresponseCallback(responseData) {

// alert("111");

console.log("OC中返回的参数:",responseData)

});

};

})

}

2-2、安卓端回调（enjoy为 HTML DOM对象）

enjoy.onclick =function() {

if(isAndroid){

window.jsObj.HtmlcallJava2(kuang.innerHTML);

}

console.log('触发了分享按钮');

//bridge.callHandler('game', {'blogdURL': 'weidsfdl'},function(response) {})

};
