<iframe src="..." style="border:none; width:100%; height: 100vh;"></iframe>

嵌入式的一行程序解决方案: 从最小大小开始，增加到内容大小。不需要脚本标记。

<iframe src="http://URL_HERE.html" onload='javascript:(function(o){o.style.height=o.contentWindow.document.body.scrollHeight+"px";}(this));' style="height:200px;width:100%;" > < / iframe >

简单性:

var iframe = $("#myframe");
$(iframe.get(0).contentWindow).on("resize", function(){
    iframe.width(iframe.get(0).contentWindow.document.body.scrollWidth);
    iframe.height(iframe.get(0).contentWindow.document.body.scrollHeight);
});

Javascript被放置在头文件:

function resizeIframe(obj) {
        obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
      }

下面是iframe html代码:

<iframe class="spec_iframe" seamless="seamless" frameborder="0" scrolling="no" id="iframe" onload="javascript:resizeIframe(this);" src="somepage.php" style="height: 1726px;"></iframe>

Css样式表

>

.spec_iframe {
        width: 100%;
        overflow: hidden;
    }

<iframe src="..." style="border:none; width:100%; height: 100vh;"></iframe>

<script type="application/javascript">

function resizeIFrameToFitContent( iFrame ) {

    iFrame.width  = iFrame.contentWindow.document.body.scrollWidth;
    iFrame.height = iFrame.contentWindow.document.body.scrollHeight;
}

window.addEventListener('DOMContentLoaded', function(e) {

    var iFrame = document.getElementById( 'iFrame1' );
    resizeIFrameToFitContent( iFrame );

    // or, to resize all iframes:
    var iframes = document.querySelectorAll("iframe");
    for( var i = 0; i < iframes.length; i++) {
        resizeIFrameToFitContent( iframes[i] );
    }
} );

</script>
