<body style="margin:0px auto; padding:0; overflow:hidden; background-color:transparent;"><p>

console.log(‘document.body.clientHeight ‘ + document.body.clientHeight);

var timerid = window.setInterval(loadimagefinish,5000);

webview 设置为300*280

比较两个物料发现
物料一
<meta name="viewport" content="initial-scale=0.5 user-scalable=no" />
物料二
<meta name="viewport" content="width=device-width, user-scalable=no">
个人认为：由于设置了viewport导致物料二中document.body.clientWidth 返回宽度是设备的宽度，document.body.clientHeight 高度按照300＊280的比例等比例放大了 280*（768/300）＝716.8（约等于717）
获取webview的实际宽度可以考虑使用window.innerWidth,window.innnerHeight.(资料现实这两个返回的值不包括边框宽度)
