function reinitIframe(){
    var myframe = document.getElementById('myFrame');

    var bHeight = myframe.contentWindow.document.body.scrollHeight;
    var dHeight = myframe.contentWindow.document.documentElement.scrollHeight;

}
window.setInterval("reinitIframe()", 200)

iframe也要有一个默认的高度

<iframe src="medicalRecord.html" frameborder="0" name="myFrame" id="myFrame" scrolling="no"  onload="this.height=100"></iframe>
