Hbuilderx打包app,视频不能横屏全屏，网页中可以

将下面的代码注入到要跳转的H5网页

if(plus.os.name =='Android'){

     console.log('Android');

    varself = plus.webview.currentWebview(); 

    self.setStyle({videoFullscreen:'landscape'//横屏 });

}else{

        console.log('IOS');

        varvideoElem =document.querySelector('video');//video元素 // video元素开始全屏

        // video元素开始全屏 

         videoElem.addEventListener('webkitbeginfullscreen',function(){ 

                 plus.screen.lockOrientation('landscape');

         });

            // video元素全屏结束

             videoElem.addEventListener('webkitendfullscreen',function(){ 

                 plus.screen.lockOrientation('portrait'); 

             });

 }
