在开发项目过程中,用iframe嵌套,会发现一个问题,用iframe嵌套的html结构右边不会自动适应高度。

这时候找到了一个解决方法:

<iframe name="my_iframe" id="mainframe" marginheight="0" marginwidth="0" frameborder="0" scrolling="no" width="100%" height="100%" src=""></iframe>

 

2、记住要引入iframe.js文件
<script type="text/javascript" src="js/iframe.js" ></script>

 下面是iframe.js的具体内容

var browserVersion = window.navigator.userAgent.toUpperCase();var isOpera = browserVersion.indexOf("OPERA") > -1 ? true : false;var isFireFox = browserVersion.indexOf("FIREFOX") > -1 ? true : false;var isChrome = browserVersion.indexOf("CHROME") > -1 ? true : false;var isSafari = browserVersion.indexOf("SAFARI") > -1 ? true : false;var isIE = (!!window.ActiveXObject || "ActiveXObject" in window);var isIE9More = (! -[1, ] == false);function reinitIframe(iframeId, minHeight) {    try {        var iframe = document.getElementById(iframeId);        var bHeight = 0;        if (isChrome == false && isSafari == false)            bHeight = iframe.contentWindow.document.body.scrollHeight;        var dHeight = 0;        if (isFireFox == true)            dHeight = iframe.contentWindow.document.documentElement.offsetHeight + 2;        else if (isIE == false && isOpera == false)            dHeight = iframe.contentWindow.document.documentElement.scrollHeight;        else if (isIE == true && isIE9More) {//ie9+            var heightDeviation = bHeight - eval("window.IE9MoreRealHeight" + iframeId);            if (heightDeviation == 0) {                bHeight += 3;            } else if (heightDeviation != 3) {                eval("window.IE9MoreRealHeight" + iframeId + "=" + bHeight);                bHeight += 3;            }        }        else//ie[6-8]、OPERA            bHeight += 3;        var height = Math.max(bHeight, dHeight);        if (height < minHeight) height = minHeight;        iframe.style.height = height + "px";    } catch (ex) { }}function startInit(iframeId, minHeight) {    eval("window.IE9MoreRealHeight" + iframeId + "=0");    window.setInterval("reinitIframe('" + iframeId + "'," + minHeight + ")", 100);}
