I am trying to create a click event on an iframe:
This is what I'm trying but without success:
$('iframe').contents().find('#theButton').click();
What I'm I doing wrong here?
As a security principle; You are not allowed to do anything in an iframe that's base uri is different from what is in the address bar; You just allowed to manipulate the iframe'e that's src tag is equal to page's.
Think about what would be happen if you insert a bank's internet banking in an iframe and cheate the people and in backend change the source of money transfers to your own account :D
but what you can do is to get the html source code of the where you want to show in an iframe; and show it using javascript; then you will be able to treat with that source code like your own.
try in this way it will work for u
$('iframe').load(function(){
var iframe = $('iframe').contents();
iframe.find("div").click();
});

I'm trying to create a visual editor where the user creates a 3D scene, and my application writes the code for the project itself. I want to create a testing feature where the code that was generated is run. I've looked into using iframes, but as far as I know, you need a specific URL for iframe.
Here are some ideas/solutions I've come up with:
Is there a way to manually feed code to an iframe, without a file or URL?
Is there any other easier way to accomplish this task?
Can this be done without server side code?
Let me know if you need any more information. Thanks!
Yes it is possible however a much simpler way would be to just create another html file somewhere on your server/host and just disallow external access to it so it's only accessible from the iframe.
You have to use an script to give code to an iframe without a source file like this:
<iframe id="my-iframe"></iframe>
<script>
document.getElementById("my-iframe").contentDocument.write("<h1>Hello World</h1>");
</script>
Change the JavaScript to this to overwrite all of the content of the iframe:
var iframe = document.getElementById("my-iframe");
var iframeDocument = iframe.contentDocument || iframe.contentWindow.document;
iframeDocument.body.innerHTML = "<h1>Goodbye World</h1>";
This overwrites all the content of the iframe with your own.
This will work but it will be a big pain to format the html from the iframe. Also as far as I know this is the simplest way that fits your needs.
I wonder if it is possible to get the page title of an url within IFRAME. I tried to use jQuery $('#iframe').attr('title') but that doesn't work. Please help. Thanks.
I think this is what you're looking for:
$(document).ready(function()
{
alert($('#iframe').contents().find("title").text());
});
That will return the page title that is located in the <title> tag of the iframe document that has the id "iframe".
I misread your question.
$('title', frames[frameName].document).text();
If what you are looking for is a way to get the URL of the iframe after the user has clicked on a link within that iframe, this is not possible in any modern browser that blocks cross-domain attempts.
Even though the iframe is part of the DOM and you can easily find the new iframe URL using apps like Firebug, Firefox will throw a XSS error on any attempts by js to directly pull that info.
But for the record, as it's already been said, the location within the DOM of the actual URL of the iframe content is (with a little help from jquery) : $("#id_of_iframe).contentDocument.location.href
I'm not totally sure if the above points straight to it with the above syntax, but that's the gist of it. The part that is a no-no is trying to go inside that contentDocument part.
After going through numerous threads on numerous forums none of them come close to a solution to what I want to accomplish.
Here is want I want to accomplish:
I have a page on an iframe and I want to click a on a div tag inside that Iframe.How do I go about it .i have seen scripts that have mouse event emulator but I do not know how to use them.
Site 1 = http://site1.com/page.html
Site 2 = http://site2.com/abc.html
code for site 2:
Code:
<div>
<div>
<div attribute="text" onClick="somefnc();">
james bond
</div>
</div>
</div>
code for site 1:
Code:
<iframe src="http://site2.com/abc.html></iframe>
What I would like to do is to have a script that automatically click on james bond (the text within the div) bearing in mind I have no control over http://site2.com/abc.html
Preferably list the methods one could accomplish this and where can i learn such type "DOM" (javascript mainly dealing with mouse events) for free.
Any references are highly appreciated.A baby step walk through the code is highly appreciated.
I am noob in this area.
What I a have tried so far:
try 1: javascript
.click();
error of try 1:cross domain issues
try 2: mouse emulation
error of try 2: noobieness code to complex for me
please help.
guessing solutions
mouse emulation like scripts
some neat jquery code
AJAX ,PHP maybe
Unfortunately since you are dealing with two sites on different domains, I don't think it's possible.
Mouse Emulator
Mouse emulator scripts probably dispatch a click event on the page, but unfortunately dispatchEvent won't work for iframes on different domains. Can you post a link or code what you tried with mouse emulation?
If you tried:
document.elementFromPoint(x, y).click();
Based on this Stack Overflow post, the click won't work on a cross-domain iframe:
How to simulate a click by using x,y coordinates in JavaScript?
Quoted: "For instance, it can't be used to trick a cross-domain iframe document into thinking it was clicked."
If you tried:
el.dispatchEvent("click");
Then you need to get the element el somehow from within the iframe contents. Since the iframe is in another domain, you will be blocked from trying to get the iframe contents (using either JQuery or DOM).
var doc = iframe.contentDocument || iframe.contentWindow.document; // security error due to cross-domain
doc.getElement ...
(By the way, it would be easier to use jQuery to get the element since site2's code doesn't have an id on the element, and DOM doesn't provide an easy way to get elements besides by id or class)
JQuery
JQuery provides a function to get the contents of an iframe. Assuming that would work, then you could find the element in the iframe contents and trigger a click on the element. Unfortunately this will only work if the iframe is on the same domain.
var el = $("iframe").contents().find("div[attribute='text']"); // security error due to cross-domain
el.trigger("click");
AJAX, PHP
I can't think of a way to click something through AJAX or PHP. Using AJAX, you could potentially make a GET request to site2 to retrieve the contents of abc.html and insert that on your page, but again, you would have cross-domain issues performing a GET request to another domain from the browser. Instead, you could make a server-side request to get the abc.html (using PHP or other server side code), then you wouldn't have the cross-domain issue. You'd still need to request any css and whatever javascript file where the somefnc() function lives and whatever else it depends on, then somehow inject all that on your page and you still wouldn't actually be interacting with site2, just copies of its files. This would be hacky and tricky to get working, and it really depends on what site2's somefunc() does.
Other options:
Depending on what you need to do and what site2's somefnc() does, you could try to duplicate the same functionality instead of doing it through clicking on an iframe.
If you can work with site2, you could try postMessage to send a message to site2:

i am dynamically creating an iframe then calling aspx pages into it, what i need to do is access the elements of the iframe page and change its ( only specific element like text box or label etc.) value without reloading the whole page.
the first task is to access the elements of pages being called into my iframe, i am trying to acess them with javascript but no progress so far.
i have tried various solution like this :
How to get the body's content of an iframe in Javascript?
Actually, the answer you've attached should work. But note that this is only true in case that your parent page and the iframe URL are loaded from the same host (domain name). if not, you will get an error message from your browser stating that this operation is blocked.
If you are trying to show another site through and iframe and then manipulate it then you have to give up this dream because it can't happen that simply.
I can think of one solution for you, not sure about the legality of it, and it is kind of a pain in the ass.
You can open up a server side script on your own domain that receive a URL, fetches it's content and then echo it. This way you get the original desired page contents but you have it on your own host so you can manipulate it as mention in the attached answer.
Note that it's not easy at all to control from there, because once a user clicks a link in the page his out of your control again, so you may want to change all the page links to the address of your server side script and attach the original link to let it fetch it for you. Probably a lot more issues that i haven't thought about.
PHP Example of such a function:
function fetchURL() {
$urlToFetch = urldecode($_GET['url']);
$contents = file_get_contents($urlToFetch);
// maybe here manipulate links and other stuff throw str_replace or,
// if you want more control over it, you may want to load it in to some DOM parser class,
// manipulate it and extract the result back to a string variable.
echo $contents;
}
Note that in that case you should load the script through the iframe with the desired URL as a query string like that:
$yourDesiredURL = 'http://www.example.com';
echo '<iframe src="http://www.yourdomain.com/your/script/path.php?url=' . urlencode($yourDesiredURL) . '"></iframe>';
*************** EDIT *****************
Actually now i see that you tagged .NET, so my example code is probably not the best for you, but since it's very short and simple it wouldn't be any problem converting it.
Again, i want to say that iv'e never tried it and it's probably over your (and my) head, maybe you better give up on the idea.
