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); }
