我的页面上有两个 iframe。一种称为导航,另一种称为内容。在加载 iframe 时,我调用以下函数:
function resizeIframe(obj) {
if (obj.contentWindow != undefined && obj.contentWindow != null && obj.contentWindow.document != undefined && obj.contentWindow.document != null) {
obj.style.height = obj.contentWindow.document.body.scrollHeight + 20 + 'px';
obj.style.width = obj.contentWindow.document.body.scrollWidth + 'px';
}
}
我像这样在 iframe 上调用上述函数
<iframe src="Taxonomy.htm" name="navigation" id="navigation" width="250" height="900" seamless="true" onload="resizeIframe(this)"></iframe>
<div id="divContent"><script>
document.write('<iframe src="' + newPath + '" id="content" name="content" width="700" height="900" seamless="true" onload="javascript:resizeIframe(this)">');
document.write('</iframe>');
</script></div>
doContentLoad()
当单击导航中的链接时,我调用另一个函数Iframe
,该函数如下所示:
function doContentLoad() {
var navFrameElem = indow.parent.document.getElementById("navigation").contentWindow || window.parent.document.getElementById("navigation").contentDocument;
if (navFrameElem != null && navFrameElem.document)
navFrameElem = navFrameElem.document;
if (navFrameElem != null) {
if (navFrameElem.body.scrollHeight > 900) { window.parent.document.getElementById("navigation").parentNode.parentNode.style.height = navFrameElem.body.scrollHeight + 130 + 'px';
window.parent.document.getElementById("navigation").style.height = navFrameElem.body.scrollHeight + 130 + 'px';
navFrameElem.body.style.height = navFrameElem.body.scrollHeight + 'px';
}
}
var contentFrameElem = window.parent.document.getElementById("content").contentWindow || window.parent.document.getElementById("content").contentDocument;
if (contentFrameElem != null && contentFrameElem.document != null && contentFrameElem.document) contentFrameElem = contentFrameElem.document; window.parent.document.getElementById("content").style.height = contentFrameElem.body.scrollHeight + 30 + 'px';
}
Firefox : Error: Permission denied to access property 'document'
我在这两个函数中都收到以下错误。
在IE I get: invalid calling object.
如何在此处获取文档对象?还是有更好的调整大小Iframes
?
