在jQuery中，这是我最好的选择，这真的帮助了我!!我等待着帮助你!

iframe

<iframe src="" frameborder="0" id="iframe" width="100%"></iframe>

jQuery

<script>            
        var valueSize = $( "#iframe" ).offset();
        var totalsize = (valueSize.top * 2) + valueSize.left;

        $( "#iframe" ).height(totalsize);            

</script>

<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>

<iframe src="usagelogs/default.aspx" id="iFrame1"></iframe>

以上方法均不能工作。

javascript:

function resizer(id) {
        var doc = document.getElementById(id).contentWindow.document;
        var body_ = doc.body, html_ = doc.documentElement;

        var height = Math.max(body_.scrollHeight, body_.offsetHeight, html_.clientHeight, html_.scrollHeight, html_.offsetHeight);
        var width = Math.max(body_.scrollWidth, body_.offsetWidth, html_.clientWidth, html_.scrollWidth, html_.offsetWidth);

        document.getElementById(id).style.height = height;
        document.getElementById(id).style.width = width;

    }

html:

<div style="background-color:#b6ff00;min-height:768px;line-height:inherit;height:inherit;margin:0px;padding:0px;overflow:visible" id="mainDiv"  >
         <input id="txtHeight"/>height     <input id="txtWidth"/>width     
        <iframe src="head.html" name="topFrame" scrolling="No" noresize="noresize" id="topFrame" title="topFrame" style="width:100%; height: 47px" frameborder="0"  ></iframe>
        <iframe src="left.aspx" name="leftFrame" scrolling="yes"   id="Iframe1" title="leftFrame" onload="resizer('Iframe1');" style="top:0px;left:0px;right:0px;bottom:0px;width: 30%; border:none;border-spacing:0px; justify-content:space-around;" ></iframe>
        <iframe src="index.aspx" name="mainFrame" id="Iframe2" title="mainFrame" scrolling="yes" marginheight="0" frameborder="0" style="width: 65%; height:100%; overflow:visible;overflow-x:visible;overflow-y:visible; "  onload="resizer('Iframe2');" ></iframe>
</div>

Env: IE 10, Windows 7 x64

我发现这个调整器工作得更好:

function resizer(id)
{

    var doc = document.getElementById(id).contentWindow.document;
    var body_ = doc.body;
    var html_ = doc.documentElement;

    var height = Math.max( body_.scrollHeight, body_.offsetHeight, html_.clientHeight,     html_.scrollHeight, html_.offsetHeight );
    var width  = Math.max( body_.scrollWidth, body_.offsetWidth, html_.clientWidth, html_.scrollWidth, html_.offsetWidth );

    document.getElementById(id).height = height;
    document.getElementById(id).width = width;

}

注意，样式对象被删除了。

对于angularjs的directive属性:

G.directive ( 'previewIframe', function () {
return {
    restrict : 'A',
    replace : true,
    scope : true,
    link : function ( scope, elem, attrs ) {
        elem.on ( 'load', function ( e ) {
            var currentH = this.contentWindow.document.body.scrollHeight;
            this.style.height = eval( currentH ) + ( (25 / 100)* eval( currentH ) ) + 'px';
        } );
    }
};
} );

注意百分比，我插入它，这样你可以对抗缩放通常做的iframe，文本，广告等，简单地放0如果没有缩放是实现

我使用这段代码自动调整所有iframe(类autoHeight)的高度，当他们加载在页面上。经过测试，它可以在IE, FF, Chrome, Safari和Opera中工作。

function doIframe() {
    var $iframes = $("iframe.autoHeight"); 
    $iframes.each(function() {
        var iframe = this;
        $(iframe).load(function() {
            setHeight(iframe);
        });
    });
}

function setHeight(e) {
  e.height = e.contentWindow.document.body.scrollHeight + 35;
}

$(window).load(function() {
    doIframe();
});
