Changing a divs content from within an iFrame - javascript

I have the following page layout
<div id="userscore" >test</div>
<iframe name="frameContent" id="frameContent" width="100%" height="100%" frameborder="0" />
The iFrame gets its content dynamically including its javascript.
When I try to access userscore from within the iFrame
console.log(window.parent.document.getElementById('user-score'));
I get in the console
<div id="userscore" >test</div>
When I try to use
window.parent.document.getElementById('user-score').html('Change the content');
I get
Object [object HTMLDivElement] has no method 'html'
Is there a way around this? Or can anybody shed some light as to what is going on.

A DOM-element doesn't have a method .html(). That method is an extension often seen in JavaScript-libraries like jQuery.
When using plain JavaScript you have to set the .innerHTML property if you want to alter the content of the element.
window.parent.document.getElementById('user-score').innerHTML = "New content";

check into html code for a iframe inside custom tags

I am trying to get a text inside a tag in a html of an iframe inside another custom tag.
For example, as shown in the pic, the force-record-layout-section is a custom tag inside a div and there is a iframe that I am trying to get element from.
But it seems when the iframe is inside the custom tag, neither jquery nor Document.GetElementsById/Name/Class/Tag are returns anything instead , all returned undefined.
var frame = document.getElementById("matchClassicStyleText");
console.log("iframe "+frame);
It just logged iframe undefined in the console.
When using jquery, it can locate the custom tag, but .html() returned empty.
Please help me understand if anything I have done wrong or there is other workaround.
The iframe
<iframe force-alohapage_alohapage="" height="220px" width="100%" scrolling="yes" allowtransparency="true" name="vfFrameId_1641796894366" title="accessibility title" allowfullscreen="true" lang="en-US" allow="geolocation *; microphone *; camera *" tabindex="0"></iframe>
Tried document.getElementsByName("vfFrameId_1641796894366") and it is also not working.
matchClassicStyleText is one of the div inside the loaded html of the iframe.
Thanks.

Append iframe to div without refreshing

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

Why does my Iframe lose its content when I execute JavaScript from within the frame to "slide" it's parent div?

I am new to learning js and having a problem with the following:
I have a custom block on my page that looks like this...
<div id="chat">
<iframe src="/sites/all/libraries/webim/client.php?locale=en"
height="100%" width="100%">
</iframe>
</div>
<div class="slider">
<a class="toggleup" href="#">Live Support</a>
</div>
And a function in my script.js file that looks like this...
jQuery(function() {
jQuery(".toggleup").click(function(){
jQuery("#chat").slideToggle("slow");
jQuery(this).toggleClass("toggledown");return false;
});
});
The issue at hand is that client.php returns 2 variations of a page, both of which contain close buttons that execute:
javascript:window.close();
Which I have changed to:
javascript:window.parent.jQuery('.toggleup').click()
When the JavaScript is executed, the chatbox slides closed as it should, but then all I see is:
[object Object]
where my Iframe content should be.
What am I doing wrong?
I don't really get what you are trying to do :).
All I can say for now is that using inline tags for scripts is not a good idea, try to enhance the page from inside the script.js. Are you trying to fire the click on the .toggleup with .click()? This won't work since the .click() function registers a handler for the selected object(s) - in this case you are adding an undefined handler as there are no arguments supplied. If you want to trigger the event on the element use .trigger('click'); instead. The [object Object] thingy is the string representation of an object so I think somehow you assign a stringified object to the iframes src.
Thats all I can say for now, if you specify a little more what you want to do I will try to help you :)
The problem was that I had these two elements in my custom block and both needed to be executed for everything to work.
<div id="chat">
<iframe src="/sites/all/libraries/webim/client.php?locale=en"
height="100%" width="100%">
</iframe>
</div>
<div class="slider">
<a class="toggleup" href="#">Live Support</a>
</div>
However when calling the jQuery function like this...
javascript:window.parent.jQuery('.toggleup').click()
instead of clicking the link, the box would close as expected but the div and iframe are never created.
Instead I changed the following line in my custom block from...
<a class="toggleup" href="#">Live Support</a>
to...
<a class="toggleup" href="#" id="chatbtn">Live Support</a>
and called it using
parent.document.getElementById('chatbtn').click();
instead of the previous jQuery code therefore executing everything in my custom block and not just the jQuery for closing the slide.
Hope it helps someone.

show only one div within an iframe (javascript, JQuery...)

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.

How to access frame (not iframe) contents from jQuery

I have 2 frames in one page like this (home.html)
<frameset rows="50%, 50%">
<frame id="treeContent" src="treeContent.html" />
<frame id="treeStatus" src="treeStatus.html" />
</frameset>
and then in one frame (treeStatus.html) I have something like
<body style="margin: 0px">
<div id="statusText">Status bar for Tree</div>
</body>
I want from the top window to manipulate the div located in the child frame via jquery (e.g show and hide).
I have seen several questions like this and they suggest the following
$(document).ready(function(){
$('#treeStatus').contents().find("#statusText").hide();
});
I do not know if this works with iframes but in my case where I have simple frames it does not seem to work. The code is placed inside home.html
Here is some output from firebug console
>>> $('#treeStatus')
[frame#treeStatus]
>>> $('#treeStatus').contents()
[]
>>> $('#treeStatus').children()
[]
So how do I access frame elements from the top frame? Am I missing something here?
Answer
After combining both answers here, the correct way is
$('#statusText',top.frames["treeStatus"].document).hide();
For this to work the frame must have the name attribute apart from the id, like this:
<frameset rows="50%, 50%">
<frame id="treeContent" src="treeContent.html" />
<frame name="treeStatus" id="treeStatus" src="treeStatus.html" />
</frameset>
You could grab the Frame and div you are wanting to manipulate and pass it into a variable.
var statusText = top.frames["treeStatus"].document.getElementById('statusText');
Then you can do anything you want to it through jQuery.
$(statusText).whatever();
Though sometimes you just can't get around having to use frames, keep in mind that the <frame> tag is obsoleted in HTML5. If you ever plan on moving up to HTML5, you'll have to use iFrames.
I have nested frames. In my case, to make it work i used command:
var statusText =
top.document.getElementById("treeStatus").contentDocument.getElementById("statusText");
Then, as Charles already answered, you can do anything you want to it through jQuery:
$(statusText).whatever();
https://jamesmccaffrey.wordpress.com/2009/07/30/cross-frame-access-with-jquery/
$(document).ready(function(){
$("#Button1").click(function(){
$(parent.rightFrame.document).contents().find(‘#TextBox1’).val(‘Hello from left frame!’);
});
});
But I used :
$.post("content_right.php",{id:id},function(data)
$(parent.frames["content_right"].document.body).html(data) ;
});
For a pure jquery solution (that doesn't require top.frames etc), the following seems to work:
$('some selector for item from frame' ,$('frame selector')[0].contentDocument)
This has the advantage that it works for nested frames:
$('inner frame item selector', $('inner frame selector', $('outer frame selector')[0].contentDocument)[0].contentDocument)
I used the following successfully:
$( '#foo', top.frames['bar'].document )
(also works with nested frames that are automagically appended in top.frames)
