I have a form that posts to an iFrame. The website inside the iFrame is something I have no control over. However I would like to set the display of a few images inside the iframe to "none".
<form id="testForm" method="post" target="testFrame">
<input type="hidden" name="RequestXML" ID="RequestXML" value="<Request><RedirectURL>Account/TokenRequest</RedirectURL></Request>"
</form>
<iframe id="testFrame" name="testFrame" frameborder="0" style="width:1000px;height:500px"> </iframe>
Here is my script at the top of the page:
<script type="text/javascript">
$(function () {
$("#testForm").attr("action", "http://externalwebsite.aspx");
$('#testForm').submit();
var iframe = document.getElementById('testFrame');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
//alert($("#testFrame").contents().find("body").html());
//alert(innerDoc.innerHTML);
});
</script>
Both my alerts return null in Chrome, IE and firefox. What is the best way to access the elements inside that iframe. (in chrome i dont even see the html of that website when I try to do "inspect element" and view the html)
By the way I am doing all this in a MVC4 project
Assuming this is not a cross-domain issue, try:
var body = $('#testFrame').contents().find('body');
Since this cross domain you have two options.
if you have access to the iframe code, then you can place XDM code in there, maybe easyXDM would help.
Or
you have to go server side and get your php/asp.net etc backend to go get the page and get what data it needs.

What I have and I need to do it work properly is when I'm in a "start page" and I click a button like this:
PAGE-1
Point A
It should send me to "another page" where I load dinamically an iframe taking each variable (shopID, type, max-levels and point) from the URL and print it like an iframe this way:
PAGE-2
<iframe id="frame" src="http://myappwebsite/resourcesiframe?shopId=3366&type=image&point=A" width=“XXX" height=“XXX"></iframe>
I've used this javascript snippet but anyway, I can't make it work properly at all.
$(".map-button").click(function (e) {
e.preventDefault();
$("#frame").attr("src", $(this).attr('data - iframe - src'));
});
I only need to get the variables from the data-iframe-src and use them in the iframe, but I'm not able... The problem is that I load elements in different pages, so I don't know how this affect to the URL variables.
I've founded a simple solution for my problem here and it works for me.
First of all I put this simple iframe in my PAGE-2:
<iframe id="frame" src="" width="100%" height="auto" frameborder="0" scrolling="yes"></iframe>
Then in PAGE-1 I've used this type of links:
https://myappwebsite/page-2?shopId=1234&type=image&max-levels=1&point=A
So now my PAGE-2 loads properly with these params in the URL. Then I've used this simple snippet in Javascript to fill my iframe in PAGE-2:
<script type="text/javascript">
$( document ).ready(function() {
$("#frame").attr("src", "https://myappwebsite/resourcesiframe" + window.location.search);
});
</script>
And it works! Now I can go to PAGE-2 with all my params, pick them and use them in SRC inside the blank iframe.
Thanks for getting me in the correct path!
I'm simply trying to load another webpage in my webpage using the object tag or iframe. Then, I would like to remove some element of the loaded page with jQuery.
Here is my code
<div>
<object type="text/html" data="http://ebird.org/ebird/map/eurtre1" width="100%" height="400px" id="eurtre1">
</object>
</div>
<script>
jQuery( window ).load(function() {
jQuery('#map-sidebar').remove();
});
</script>
And, as you guess, it is not working...
I have tried:
jQuery('#eurtre1').contents().find('#map-sidebar')
and
jQuery('#eurtre1')[0].contentDocument.children
The wired thing is that on my browser, I can do it in the console, once I've selected the inside of the object...
Any idea ?
Here's a link to a similar question:
how to access an iframe and affect it with jQuery
Basically you can't due to Javascript same-origin policy but if you have access to the loaded content in the iframe you could use window.postMessage
You could also add a parameter to the iframe's src tag to post a message, something like this:
<iframe src="http://www.example.com?hideElement=true"></iframe>
Again you will have to have access the content of the iframe to check the param and execute your code.
Here's my html/javascript. Below there are two if statements that I've tried. I used indexof to get the text between the <a></a> tags. Also tried href == to use the href= contents. Both do not work.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>pb</title>
<script type="text/javascript">
function call() {
alert("Called!");
var allAnc = document.getElementById("d").contentDocument.getElementsByTagName("a");
for (var i = 0; i < allAnc.length; i++) {
if (allAnc[i].href.indexOf("Flag") > 0) {
alert("Found link by indexof, Trying to click!");
(allAnc[i]).click();
break;
}
if (allAnc[i].href == "javascript:flag.closeit()") {
alert("Found link by href, Trying to click!");
(allAnc[i]).click();
break;
}
}
}
</script>
</head>
<body>
<input id="Button1" type="button" onclick="call()" value="button" />
<iframe id="d" src="sourceurl.html" width="100%" height=700"></iframe>
</body>
</html>
Here is the link inside the iframe I am trying to click:
<a style="text-align: left;" href="javascript:flag.closeit()" title="Flag">Flag</a>
From your comment, you are loading the content of different domain into you iframe, so you just can't read the content of that domain due to same origin policy restrictions.
Here's a demo of the issue, code mostly copied & pasted from your question:
http://jsfiddle.net/colllin/G2BDb/
And the inner iframe code is here:
http://jsfiddle.net/colllin/wc8Up/
As you can see in the console when you click the button,
Refused to display 'https://www.google.com/#Flag' in a frame because
it set 'X-Frame-Options' to 'SAMEORIGIN'.
So it looks like if you have control over the page that the iframe is linking to, you could set X-Frame-Options header on that page to be specify an ALLOW-FROM uri (from MDN):
ALLOW-FROM uri
The page can only be displayed in a frame on the specified origin.
Alternatively if you have control over the original iframe source (which I assume you do, otherwise it's impossible to even access the contents, let alone click a link), you could add the target="_top" attribute to the link before clicking it. This would cause the linked page to replace your top-level page in the window.

How to call a javascript function in ifram from parent window.
i have a jsp page which contains an iframe.
jsp page is served by "a.yenama.net" server and iframe is served "b.yenama.net" server.
<iframe width="1200" height="640" name="data" id="dataId" >
</iframe>
<br/>
<input type="button" name="data" value="Save data" onclick="callSaveData();" />
tried below code from parent jsp page and recieved permission denied error in IE
window.frames['data'].callData();
also tried
document.getElementById('dataId').contentWindow.callData(); //didn't work
Function in iframe
window.callData = function(){
alert('Iframe function');
}
your help is truly appreciated.
you can do that by declaring your function in a common .js file
Therefore, you can access your function from wherever you want.
Have a nice day
i would suggest you to use jquery.load method instead of iframe to load your second page in a div of first page and then you can call any methods from both the pages
$('#result').load('PageWhichYouAreOpeningInIFrame.html');
or if you still wants to go with IFrame then you can use:
Invoking JavaScript code in an iframe from the parent page
http://api.jquery.com/load/
I know there are many topics about it, but none of them worked. I need just to get iframe content(not source code).
I have a form, that posts some parameters to another server and I target it to iframe(that lies on the same page). So I receive server responce code storred in my iframe without page refresh:
<form name='vin_form' id='file_upload_form' action='*****' method='post'>
<input name='name1' value='value1'>
<input name='name2' value='value2' type='hidden'>
<input name='name3' value='value3' type='hidden'>
<div onclick=\"document.getElementById('file_upload_form').target = 'upload_target'; document.vin_form.submit();\">Send form</div>
</form>";
<iframe id='upload_target' name='upload_target'></iframe>
To get iframe content I used everything, but nothing worked:
jQuery('#upload_target').load(function()
{
alert(jQuery('#upload_target').contents().find('body').html());
var myIFrame = document.getElementById('upload_target');
var content = myIFrame.contentWindow.document.body.innerHTML;
alert(content);
alert(window.frames.upload_target.document.body);
}
);
I read about "same origin policy", but I think it shouldn't be forbidden in my case, because I can access that page by url and read all the code, so why I can't do it programmatically?
P.S.: Are there some other ways to get form responce code from another server? (php curl doesn't work because of some site framework defence)
*update - try this:
var t = document.getElementById("upload_target");
var y =( t.contentWindow || t.contentDocument);
alert(y.document.body.innerHTML)
