I have a sort of index at the bottom of an iframed page with 4 different id iframes. I would like to click a link in the index and jump to the iframes position (#TOP) for example then load a html page in the targeted iframe with just one link. How can I do that with JS or something. I have seen snippets that load 2 iframes but I only want to jump to the anchor location THEN load the html resource inside the targeted iframe. I would think there is a simple JS to do that but cant seem to find one. Still learning here so thanks for the help.
For a web page, practical reasons demand an iframe to link to other content within the domain. However, while the rest of the page (outside the iframe) doesn't need to scroll, the content within the iframe does. Rather than having a scroll bar within the iframe, how could I use the scroll bar of the page to scroll within the iframe?
The iframe links to a page from the same domain, and while it may not be possible to do this without scripting, ideally it would be a CSS-only solution. If necessary, javascript can be used.
If it helps, the iframe runs up the the bottom edge of the page, so I have been playing around with ways to extend it past the bottom and do it that way.
You would need to have the iFrame resize to the contained content to do this. A task that is after all these years still not as simple as it should be. Take a look at this lib that does the hard work for you.

Parent webpage jumps / autoscrolls to location of iframe when transition happens within an iframe. Transition happens using jquery mobile - $.mobile.changePage($(#pageName)) [ using an anchor to transition to a div ].
I have gone through various links on stackoverflow e.g., Loading iframe with an #element specified moves the parent viewpoint to the same location (hiding iframe till it loads and page changes but it doesn't solve the issue)
There were few other links that mentioned a) About window.parent scrollToTop when iframe loads but I do not want the parent page to scroll at all when page within an iframe changes. b) Changing focus to parent page when iframe loads but it didn't help too. (Note page transitions to another div in an iframe so it seems we need to use anchor tags as per jquery mobile). Is their a way to stop this parent page autoscrolling ? Any help is appreciated.
Issue was jQuery mobile's focusPage, which was autofocusing content within an iframe. To change this behavior - I added below mentioned javascript in of webpage displayed within an iframe
<script type="text/javascript">
if (self != top) { //if inside iframe
//don't use focusPage for embedded site to prevent autoscroll
$.mobile.focusPage = function ( page ) {
return;
}
}
</script>
Note: This link helped in resolving this issue : When within iframe JQuery Mobile autoscrolls to the iframe top
I am trying to add dynamic image gallery to a site I am working on but I am limited to only HTML and css. So I made a separate page on my own server with required php file to create the gallery and used Iframe to load the gallery page to the site.
Problem is now there is two separate scroll bars. one to scroll the content in the iframe and one for the parent page. This makes scrolling on the page very messy. Is there any way so that I can get rid of the scroll bar for the Iframe and be able to scroll through the content within the Iframe from the parent page. Anyway I can make the Iframe behave like a div? I thought the best way would be to set the height of iframe so the height of iframe would change to fit whatever the content that's in it. This way I thought there wouldn't be need for a scroll bar on the iframe.
Here is the gallery page I am trying to load with Iframe http://lejund.com/plugin/#*
I am open to all your suggestions. Is there better way to achieve this other than the Iframe?
Thank you
I found this solution on github by davidjbradshaw.

It's using window.postmessage to achieve this.
Is there any way to stop an iframe re-loading its contents when I change its position within the DOM? Simple example:
<script type="text/javascript">
function moveiframe() {
var dest = document.getElementById('newparent');
dest.appendChild(document.getElementById('googleframe'));
}
</script>
<iframe src="http://www.google.com" id="googleframe"></iframe>
<input type="button" onclick="moveiframe()" value="Move" />
clicking the "Move" button changes the parent of the iframe, and reloads its contents (in Firefox and Chrome, but not IE).
Any suggestions would be much appreciated!
[Updated with background info]
I'm loading the site's adverts in placeholder divs at the bottom of the page (to prevent advert loading from holding up the page load) - and then shifting the divs they've been written in to their correct container once loaded. It all works great... unless the ad that gets served uses an iframe (like google adsense) in which case the ad gets loaded twice and the serving is messed up.
Considering the simplicity of your test case, it looks like the only methods you have available to put an element inside another will always force the contents to reload.
[Edit] After seeing what you're trying to do, there are a couple things you can try:
All ads could be served in IFRAMEs (on your own site) which will not hold up loading of the page and can be placed in the right place right away.
As mentioned above IFRAMEs won't hold up loading of the page so you could put the ads in place right away if they are IFRAMEs and load them at the bottom if they are something else. Of course, this won't work if the slow part is before you know if you are going to get an IFRAME or not.
You could keep the content in it's placeholder DIV but when it's done loading just reposition (with CSS absolute positioning) over the right place in the page. Not the most elegant solution, but should work fine.
I'm regretting my original answer, as it seems to be causing other headaches. Here's a few other potential solutions that you may not have tried:
Place the ad scripts inside of divs with their display style set to none. Then, move them to their final desintation and change them to display: block after the page has loaded. Perhaps this would prevent the iframes from loading their content inititially.
Try the same thing, only with visibility set to hidden, then changed to visible.
A quick guess would be to unset the value of the src attribute of the iframe element or set it to "about:blank".
It is up to you to restore the previous value (or any value) to the src attribute of the iframe (using JavaScript).
Regards,
If the ads are a fixed size, you could place them in absolutely-positioned divs instead. Then, once the page loads, you could move those container divs to their designated spots. There are a lot of Javascript samples out there for calculating an absolute position from a relative position. Of course, you would have to reserve space visually in the destination divs so the ads wouldn't cover the content.
What about using an ajax request to load the ad's contents, and adding the contents to the DOM when the ajax call returns, instead of using an iframe?
