iframe去滚动条

<iframe name="myFrame" id="myFrame" frameborder="0" src="tab.action" style="margin:0 auto;width:100%;height:100%;" scrolling="no"></iframe>

iframe自适应屏幕大小

function resetIframeScreen(){
    var myFrame= document.getElementById("myFrame");
    var bheightT = document.documentElement.clientHeight;
    myFrame.style.width = ‘100%‘;
    myFrame.style.height = (bheightT  - 50) + ‘px‘;
}
resetIframeScreen();
window.onresize=function(){
    resetIframeScreen();
};
