jQuery scroll to top of iframe parent
I have an iFrame with a feedback form in it. After the user clicks submit, I want use parent window to scroll to the top. I know I can scroll to the top of a page with:
$('htm开发者_Python百科l, body').animate({scrollTop:0}, 'slow');
However, this will only scroll the contents of the iframe, not the parent page. Any suggestions?
Give a try for this one :
window.parent.$("body").animate({scrollTop:0}, 'slow');
This seems to do the trick as well:
$('html, body', window.parent.document).animate({scrollTop:0}, 'slow');
The second parameter to $ is the context to search in.
<script>
jQuery(document).ready(function($) {
FB.Canvas.scrollTo(0,0);
FB.Canvas.setSize({width: 760, height:$('body').height()+20});
});
function scrollTo(x,y) {
$("body").append('<iframe id="scrollTop" style="border:none;width:1px;height:1px;position:absolute;top:-10000px;left:-100px;" src="http://static.ak.facebook.com/xd_receiver_v0.4.php?r=1#{%22id%22%3A0%2C%22sc%22%3Anull%2C%22sf%22%3A%22%22%2C%22sr%22%3A2%2C%22h%22%3A%22iframeOuterServer%22%2C%22sid%22%3A%220.957%22%2C%22t%22%3A0}[0%2C%22iframeInnerClient%22%2C%22scrollTo%22%2C{%22x%22%3A'+x+'%2C%22y%22%3A'+y+'}%2Cfalse]" onload="$(\'#scrollTop\').remove();"></iframe>');
}
</script>
Within the Iframe page.
window.parent.ScrollToTop(); // Scroll to top function
On The parrent page:
window.ScrollToTop = function(){
$('html,body', window.document).animate({
scrollTop: '0px'
}, 'fast');
};
<body onLoad="window.parent.scroll(0,0);">
In the body of the iframe's html page
Its as simple as you can do!
