WKWebView的JS与Native的交互，适配iOS和and

JS调用native的HTML代码示例：

<script type="text/javascript">

var toHome = function(){

if (typeof(android)=='undefined')

window.webkit.messageHandlers.nativeToHome.postMessage('');

else

android.toHome();

}
var share = function(shareinfo){

if (typeof(android)=='undefined'){

window.webkit.messageHandlers.nativeShare.postMessage(shareinfo)

} else {

android.share(shareinfo)

}

}

</script>

native调用JS 有返回值的代码示例：

<script type="text/javascript">

var shareinfo = JSON.stringify({

title: '多品类多列商品测试',

link: 'http://wow.mxth.com/shopping/acti_special.htm?id=18',

desc: '多品类多列商品测试',

imgUrl: 'http://wx.qlogo.cn/mmopen/Q3auHgzwzM5dVJKFHZMnL4fCCwBibQgByD2hgt3ydKTDg0sn9PZASRCibhIJfoVayLn2BaIyo443Z4RGuTtIER4Q/0'});

function wxshare(){

if (typeof(android)!='undefined'){

android.actishare(shareinfo);

return;

}

return shareinfo;

}

</script>
