Firefox reloading parent page in iframe when clicking named anchor
My site has an iframe which is dynamically populated with html content. The html often contains named anchors, which 开发者_JAVA百科work fine in IE/Chrome but in Firefox it reopens the entire page within the iframe.
Here's an example: load the page in firefox, scroll to the bottom of the iframe, click the "back to top" link, and you will see what I am talking about.
<html><head></head><body onload="setFrameContent();"><script>
var htmlBody = '<html> <head></head> <body>' +
'<a name="top"><h1>top</h1></a>' +
'<br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>' +
'<br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>' +
'<a href="#top">back to top</a></body> </html> ';
function setFrameContent(){
if (frames.length > 0) {
var d = frames[0].document;
d.open();
d.write(htmlBody);
d.close();
}
}
</script>
<h1>Here's an iframe:</h1>
<iframe id="htmlIframe" style="height: 400px; width: 100%"><p>Your browser does not support iframes.</p></iframe>
</body></html>
Any ideas?
I had the same problem and found this workaround.
<html>
<head>
<script>
var htmlBody = '<html> <head></head> <body>' +
'<a id="top"><h1>top</h1></a>' +
'<br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>' +
'<br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>' +
'<a href="javascript:parent.gotoAnchor(\'top\')">back to top</a></body> </html> ';
function setFrameContent(){
if (frames.length > 0) {
var d = frames[0].document;
d.open();
d.write(htmlBody);
d.close();
}
}
function gotoAnchor(id)
{
var el = null;
el = window.frames['myiframe'].document.getElementById(id);
window.frames['myiframe'].scrollTo(0,el.offsetTop);
}
</script>
</head>
<body onload="setFrameContent();">
<h1>Here's an iframe:</h1>
<iframe name="myiframe" id="htmlIframe" style="height: 400px; width: 100%"><p>Your browser does not support iframes.</p></iframe>
</body>
</html>
Hope this helps.
