篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了iframe标签父页面高度自适应相关的知识,希望对你有一定的参考价值。
注意:页面html节点上要有
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<iframe id="mainFrame" name="mainFrame" scrolling="no" src="Index.aspx" frameborder="0" style="padding: 0px; width: 100%; height: 1000px;"></iframe>
调用
<script type="text/javascript"> startInit(‘mainFrame‘, 560); </script> <script> 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); } </script>
测试发现兼容浏览器ie6-11、chrome、firefox、opera、Safari、傲游云浏览器、360浏览器,兼容性更好,其他未测试
