I have a page where I modded an app to prepopulate a number of fields. I would like to automatically have the 'submit' button be pressed/submitted when the page loads. I have tried things like:
<script type="text/javascript">
function autoclick() {
document.getElementById('buttonid').click();
}
</script>
with
<body onload="autoclick()">
But it does not work.
Any advice would be greatly appreciated!
Thanks
(It is the iframe on this site: http://abraxas.pw)
I see that your iframe is in the same domain and hence it will possible for you as the cross-domain security may not apply.
Give your iframe an id. And then:
document.getElementById('iframeName').contentWindow.document.getElementById("buttonid").click()
More info here: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#Scripting
Make sure that the DOM is fully loaded before you fire your Javascript. Wrap this code into body load or iframe load.
Update:
If the iframe is in the same domain and is in your control, you don't need to do all this. Just fire the click from domloaded of jQuery, or place your code at the end (just before body ends). It will work.
Seeing your code, you have defined the function in the head and are calling it at body load. Place the function and the call at the end of the body.
You cannot do it in iframe for security reasons: http://pipwerks.com/2008/11/30/iframes-and-cross-domain-security-part-2/
Content coming from different domain in iframe can't be controlled in your page using javascript.
Browser treats iframe as a different window so you've no access over it. it's something like trying to access content of different window open in your browser from your own window(which is obviously not possible)

I have a same domain page loaded inside an iframe (using sandbox attribute). I use the following code to prevent clicks (and all other elements) from navigating away form the page:
$('#preview_frame').contents().find('body *').off('click').click(
function(event){
event.stopPropagation();
event.preventDefault();
}
);
However it seems that other Javascript on the page is redirecting the navigation via window.location.href or window.location.replace.
I cannot change the code of the pages inside the iframe as they are proxied from other sites.
I tried using the iframe unload event without success.
I need to disable the ability to navigate inside the iframe no matter what/how it is done. I am not talking about top parent navigation which can be disabled with the sandbox attribute, I am talking about the navigation INSIDE the iframe itself.
Is it possible to accomplish that?
Your code seems correct. Remove the sandbox attribute if the page inside iframe is from same domain. Hope it will solve the problem.
Sandbox attribute always treats contents as unique origin.
I'm looking for some help on what should be a basic script (I think), but I can't quite figure it out myself..
I have a page, with an iFrame, displaying a page that I only have access to the header.
I'd like to make it so that when someone clicks ANY link ( tag) in the iFrame window, it scrolls my parent page to the top (or a specific location).
Is this possible?
Edit: Also, if it's important, I'm already using David Bradshaw's iFrame resizer script to resize the frame on the fly, which uses postmessage to communicate frame->page. https://github.com/davidjbradshaw/iframe-resizer
Edit2: The parent window and iframe window are cross-domain
See Trigger events in iframe's parent window
Add some JS to your iframe page:
$(document).ready(function(){
$('a').click(function(){
window.parent.$(window.parent.document).trigger('scroll');
});
});
Then on the parent page:
$(document).bind('complete', function(){
//Add scroll code.
});
You could use post message to do something similar, but if you control both pages and they are on the same domain, this should work. If they are on different domains (which you didn't specify) you are stuck using postMessage which I believe isn't entirely cross-browser complient and therefore won't work on all settings and there really isn't a fallback.
If you want to use postMessage and you are using a plugin, just do something like
window.addEventListener("message",function(event){
if(event.origin == 'http://yourdomain.com'){
if(event.data == 'messageString'){
//Add scroll code
}
}
});
Ok so any help here would be great
I have a HTML page with an I frame loading a site of mine in it…
What I need to do is check in the iframe from the main document, the target attribute of a link and if it's blank, hijack it and add my own custom functionality from outside of the iframe in the main HTML document
The issue I have is the site being loaded in to the frame is on a different domain so I am not sure if this can be done? I have full control of the site been loaded in to the I frame so is there something in there I can set to allow it?
What I effectively want to do is hijack the links in an iframe which I guess could be an issue?
Can this be done, alternately does anyone know a way I could achieve what I am trying to do?
Thanks
Is it possible ?
I've made on page with iframe, I want a script that'll click automatically inside in one iframe's link.
But I also want that script to detect half link, I mean the link which is in iframe changes everytime, but the first part of the link doesnt change, so the javascript should detect half link which doesnt change and redirect to it...
Why don't you write a "client" library and import it within iFrame. This library listen to a message from HTML5 postMessage call with certain attribute and react appropriately. Since you have access to the parent object through the event object (or window.parent), you can also send response back with the result. This way, it doesn't matter if it's cross-domain and as long as this library exists, you can communicate back-and-forth and even has the iFrame initiate if you write it properly.
I can't share the code with you since it's our proprietary library, but that's part of the idea.
If the content of your iframe is from a different domain, you can't. Allowing this would be a major security concern.
If your iframe content is in the same domain, then you can access the iframe content through its contentWindow property. You can then work with your iframe link the same way you would if the link was in the main page.
I have 2 questions :
How do I know that the contents of the frame ready/loaded (as $(document.ready()))?
How do I know that the popup (window.open()) contents ready/loaded (as $(document.ready()))?
Google said that could help $("iframe").load(), but I did not understand how
DEMO — iframe
The problem with using load() is the iframe may have already loaded before the jQuery has run, thus not triggering the function. One way around this would be to initially load nothing in the iframe (about:blank), then using jQuery to change the src attribute to get the iframe to point to the desired location.
DEMO — window.open (Disable your popup blocker for this demo.)
I'm not sure whether ready() can be used cross-domain. When loading a popup/iframe on the same domain, a script on the child page can be used to report back to the parent window that it is "ready".
The load callback will be called when the iFrame will be load :
$("#iframe-id").load(function(){
//The iFrame content is loaded
})
