I have a div that contains the iframe, this iframe loads a URL which shows a page.
Within the iframe, i have a close button which when clicked, hides the div. But I am unable to access the div from within the iframe.
My code as below
<div class="app" id="modalOverlay" style="background-color:rgba(0,0,0,0.5);position:absolute;z-index:1;width:100%;height:100%;top: 0;left: 0;">
<div id="modalContainer" style="position:absolute;z-index:2;margin: -250px 0 0 -250px;top: 50%;left: 50%;background-color: #222;width: 500px;height: 500px;">
<a class="close" style="position:relative;top:-10px;z-index:3">Close</a>
<iframe src="http://www.local.dev/api/v1/track" frameborder="0" style="width:500px;height:500px;position:relative;top:-20px">
</iframe>
</div>
</div>
Within the iframe src view, i load a js which uses jquery
$(document).on('click','.close',function(){
$(document).closest('.app').remove();
});
Anyway to do this?
you can use:
$('#modalContainer', window.parent.document);
second parameter is the context in which to search.
$(document).on('click','.close',function(){
$('.app', window.parent.document).remove();
});
Try something like this:
$('#divtohide', window.parent.document).hide();
Or something like this:
$("#InFrameId").on('click', function() {
$('#divtohide', window.parent.document).hide();
});
EDIT: based on the recent update to your question if the frame is from a different domain, browser will flag this as XSS and you may not be able to do much. One way you can run scripts is if the server of the iframe is configured to send the X-XSS-Protection header with correct value.
This can be done with child to parent frame messaging.
Have the parent frame listen for a message.
<div id="myDiv">
<iframe src="childFrame.html" id="frame1"></iframe>
</div>
<script>
window.onmessage = function(e) {
if(e.data == "close") $("#myDiv").toggle();
}
</script>
The child frame can send a message to the parent frame.
<button onclick="parent.postMessage('close', '*');">Hide</button>
See my gist: https://gist.github.com/sfarthin/9140403
DhruvJoshi's method will have the browser flag this as a XSS attack.
Simply you can't, according to your code, I think your iframe comes from different domain, so a frame from different domain cant access to parent page.
Therefore you may consider using nodejs or maybe, you should read this: Cross domain iframe issue or a search with "crossdomain iframe" keywords will lead you to what you need.

I have the markup below:
<html>
<body>
<div class="aaa"></div>
<div class="aaa"></div>
<div class="aaa">
<iframe>
<form id="myform">
</form>
</iframe>
</div>
<div class="aaa"></div>
</body>
</html>
On loading the iframe, it contains the form '#myform'.
Upon submission of the form, I need to run a certain callback based on the div.aaa that is the immediate parent of the iframe.
Any solution based on parent.document cannot help me much, since I do not know the ID of the div.aaa.
What I'd like to do is something like $('#myform').closest('div.aaa'), but, of course, this fails because any element beyond the iframe window itself cannot be accessed in this fashion.
How can I best access this iframe's immediate parent div, which is actually an element in it's parent document?
Both parent and iframe are of same origin.
You can jump up to the parent window and look for specific iframe in parent document by matching frame element contentWindow to known window inside the iframe
Something like:
$(window.parent.document).find('iframe').filter(function() {
return this.contentWindow === window;
}).parent().doSomething()
DEMO
I would recommend to use .closest('.aaa'). But if you could assign a unique identifier you may use .parent('.uniq_selector') that is a bit more performant.
I want to write some jQuery code to get the content length on an element whose id="newUp" from an iframe, and if length == 0 then show the element whose class="OE" from the page:
function onframeload(){
if($( "iframe:contains('.new')" ).length > 0){
$('.oe').show()
}
};
I am a beginner in javascript.
Main page code is:
<div style="display:none;" class="oe">CHAL PEA OE!</div>
<iframe onload="onframeload();" src="//jsfiddle.net/ROYALRandhawa/Lysn9e5z/embedded/result/" allowfullscreen="allowfullscreen" frameborder="0"></iframe>
This is the code in the iframe:
<div class="news"><center>Welcome Boss</center></div>
<span id="newUp">Here is new update</span>
There's a security mechanism in browsers that prevents you from performing tasks in the iframes that doen't belong to the same domain
Take a look at this:
https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy
Using Javascript in a webBrowser Control in a form, How do I switch to a iFrame
<iframe id="ContentFrame" class="contentIFrame" onload="checkComplementaryPage()" onmouseover="hoverMenu('dividers')" name="ContentFrame" src="HomeContainer.aspx" scrolling="auto" frameborder="0"></iframe><div id="footer" class="footer">
and then locate and click on an element inside that iFrame?
<div class="innerItem50L">
<input type="submit" name="btnPunch" value="punch" id="btnPunch" style="CURSOR:hand;" />
</div>
I am new to programming and am starting with c#. I know even less about Javascript...
Using the following thread as an example:
Make an event happen in child iframe to the parent window in JavaScript?
You could do the following:
$('#ContentFrame').contents().find('#btnPunch').click();
Note: The iframe's source has to be from the same domain, and contents must be loaded so you should put it after window load.
I have a html structure like:
<div id="bar">
<iframe id="foo"></iframe>
<iframe id="foo2"></iframe>
</div>
Each iframe has javaScript running inside it.
Now: I need to add another element... <iframe id="foo3"></iframe> to the end of the div without foo & foo2 from refreshing. I thought jQueries.append() was the way to do this, but this still refreshes the original iframes (Which resets the javaScript inside the already existing iframes).
Any tips/ideas? Thanks
Below will be the code
document.getElementById("bar").innerHTML += '<iframe id="foo3"></iframe>';
Not sure if it will refresh the other iframes
First just let me say I'm open to ideas on a different approach altogether.
I have and iframe as such:
<div id="testloadlogin">
<iframe src="../security/login.aspx" width="400" height="500"
scrolling="auto" frameborder="1">
[Your user agent does not support frames or is currently configured
not to display frames. However, you may visit
the related document.]
</iframe>
</div>
The page being loaded with the iframe has a div called loginInnerBox. I only want to display the loginInnerBox and everything inside of it.
Any ideas on how to do this? I was thinking of using Jquery or javascript of some kind to remove everything else on the page loaded by the iframe, not sure how to access that though...
Just to be clear I want everything on my page outside of the iframe to remain intact. I want the equivalent of saying $.('testloadlogin').load('../security/login.aspx' #loginInnerBox) which would just get loginInnerBox's html and place it in the testloadlogin div. However I need the back-end processing from the other page which is supported by iframe, but not by the Jquery load.
The markup of the page loaded by the iframe is
<body>
<div>
</div>.......
<div class="AspNet-Login" id="ctl00_CLPMainContent_Login1">
<div id="loginInnerBox">
<div id="loginCreds">
<table>
</table>
</div>
</div>
</div>
<div>
</div>....
</body>
Do you need more information than that?
I tried this, it had no effect:
<div class="ui-corner-all" id="RefRes">
<div id="testloadlogin">
<iframe onload="javascript:loadlogin()" id="loginiframe" src="../security/login.aspx"
scrolling="auto" frameborder="1">
[Your user agent does not support frames or is currently configured
not to display frames. However, you may visit
the related document.]
</iframe>
</div>
</div>
<script type="text/javascript">
function loadlogin() {
$('<body>*', this.contentWindow.document).not('#ctl00_CLPMainContent_Login1').hide();
}
</script>
With jQuery, you can load not just the contents of a URL, but a specific CSS selector from within that URL. This would be a much cleaner approach. It's like this.
$("#area").load("something.html #content");
Via CSS Tricks
$("iframe").contents().find("*:not(#loginInnerBox)").remove();
Be aware this would only work on iframes loaded from the same domain (same origin policy)
EDIT: Probably this removes children of loginInnerBox as well. In that case you could try to clone it before:
var iframe = $("iframe").contents(),
loginBox = iframe.find("#loginInnerBox").clone();
iframe.find("*").remove();
iframe.append(loginBox);
Something like that..
Add this to the <iframe>-elememt:
onload="$('body>*',this.contentWindow.document).not('#ctl00_CLPMainContent_Login1').hide();"
it will hide every child of the body except #ctl00_CLPMainContent_Login1
If #ctl00_CLPMainContent_Login1 contains more than the loginbox, you have to use the suggestion using clone() posted by pex.
