How do I access the iframe and override the elements style "td.rank" ?
This is what I've got so far:
<script>
var head = $("#iframe11").contents().find("head");
var css = '<style type="text/css">' +
'td.rank{background-color: #fc6b0a!important;}; ' +
'</style>';
$(head).append(css);
</script>
<iframe src="http://www.example.com" id="iframe11" style="margin-left: 174px; width: 401px; border: 0px solid black; height: 358px; opacity: 0.85; margin-top: 23px;"></iframe>
When I open the code using "inspect element" - I don't even see the CSS code part in the <head> tag of the iframe.
You if would like add css style inside iframe using jQuery then just follow below steps...
1. First create 'index.html' file and add below code in it
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.6.3.min.js"></script>
<script>
$(document).ready(function() {
$('#iframe').load(function() {
$("#iframe").contents().find("head").append("<style>.text_color{color:red;}#page{margin:0;}</style>");
});
});
</script>
</head>
<body>
<iframe src="iframe.html" id="iframe" name="iframe"></iframe>
</body>
</html>
2. Next create another file called 'iframe.html' and add below code to it
<!DOCTYPE html>
<html>
<body>
<div id="text"><span class="text_color">Content inside iframe goes here<span></div>
</body>
</html>
3. Next run 'index.html' file and now see 'Content inside iframe goes here' text color will changed to red color
Ensure that the frame document is on the same origin as the framing document so you don't have a security policy violation.
Move the script so it appears after the frame so that the element exists before you try to access it
Move the code into a function and use that as a load handler for the frame so that the DOM you want to manipulate exists before you try to manipulate it

I have written this html script to display wikipedia inside iframe but i want to change the background color of it, below is the code snippet which i tried. but its not working.
<!DOCTYPE html>
<html>
<head>
<style>
body {
background-color: blue !important;
/* Adding !important will give this rule more precedence over inline style */
}
</style>
</head>
<body>
<iframe style="background-color:#fc3 !important;" src="https://www.wikipedia.org/" width="100%" height="450px" >
</iframe>
</body>
</html>
You cannot modify the contents of an iframe before loading (using CSS), because it is displaying content from another page. After it loads, you may modify it with javascript.
I have a custom list from a different sharepoint site (still the same domain) that I would like to display on my work site without the header (at a minimum, but getting rid of the ribbon would be nice too). I have attempted 4 methods without success listed below:
1) I can't even get it to work on a normal page by adding ?isdlg=1 to the end of my url (ie ..allitems.aspx?isdlg=1)
2) since I mostly work with SQL and not HTML I am sure I may have screwed up some of my tags.
<div class="ms-dlgFrameContainer">
<iframe width="1400" height="600" id="DlgFramee" class="ms-dlgFrame" frameborder="0" src="myurl.aspx">
<html class="ms-dialog">
<head>
<style type="text/css">
.ms-dialog #titleAreaBox { display:none }
</style>`
3) to hide the header of the page inside the iframe.
<script type="text/javascript">
document.getElementById("myiframe1").contentWindow.document.getElementById("titlerow").style.display = "none"; </script>`
4) Most promising. When I add
<iframe id="myiframe1" src="myurl" width="1000" height="450" frameborder="1"></iframe>
<style>
#titleAreaBox { display: none }
</style>
in the same CEWP as my iframe, it removes the title area for current page and not the page in the iframe. This exactly what I want except I want it to do that for the page inside the iframe.
5) I did this as well even just trying to change header color but didn't notice any change. I looked up the correct webpart ID.
<style type="text/css">
#MSOZoneCell_WebPartWPQ2 .ms-WPHeader
{ background-color: pink; }
</style>
You could try below jQuery script, I just hide suiteBarTop in demo.
<iframe id="myiframe" width="1400" height="600" id="DlgFramee" class="ms-dlgFrame" frameborder="0" src="/sites/tst/SitePages/Home.aspx"></iframe>
<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script type="text/javascript">
$(function () {
$('#myiframe').load(function () {
$(this).contents().find('#suiteBarTop').hide();
});
})
</script>
I'm trying to hide an element in same-origin iframe. However, this son of a bi*ch blinks for a few ms before getting hidden. So what I did was added display: none and remove it after iframe is loaded - great. But now, when user clicks inner page link of iframe, which also contains element to be hidden, it still blinks (because display:none is now removed). I need to detect when to add it again, i. e. just before another page starts to load.
Testing here: https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_script
Here is what I tried:
<html class="js">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<style>
html.js #iframeID
{
display: none;
}
</style>
<script>
$(document).ready(function()
{
$('#iframeID').on('load', function()
{
$('#iframeID').contents().find('a').on('click', function()
{
$('html').addClass('js');
console.log('click');
});
console.log('loaded');
$('#iframeID').contents().find('#mySidenav').remove();
$('html').removeClass('js');
});
});
</script>
</head>
<body>
<iframe id="iframeID" height="800px" width="800px" src="https://www.w3schools.com/" ></iframe>
<script>
</script>
</body>
</html>
However, there are some a elements that don't load another page. In this example, try clicking on "TUTORIALS" at the top of that iframed webpage - it just opens up dropdown, not loads another page.
What should I do?
I noticed that "TUTORIALS" link has href="javascript:void(0)". Maybe I should be somehow selecting all a links without such href? But not sure if it's fool proof.
You can make use of load event on the iframe as such,
$('iframe').on('load', function(){
console.log('Iframe Loaded');
});
The iframe's load event is also called every time it's src changes.
$(document).ready(function(){
$('.iFrame_class').load(function(){
console.log('frame loaded');
});
});
Alternatively on start load solution:
Custom attribute for iframe:
iframe class="iFrame" src="some site" started="0"
Put this code to iframed page:
window.parent.$('.iFrame').attr("started","0"); //makes iframe started attr to false on page load
$(document.body).on("click","a", function() {
window.parent.$('.iFrame').attr("started","1");// makes iframe started attr to true for all clicked links
});
And listen; is started attribute changed to 1 on parent page?
I fixed the damn blinking by making 2 iframes and showing 2nd while 1st one is loading. While 1st one is loading, it's also hidden, becomes unhidden after it finishes loading. Anyway, here is my code, should help someone:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<style>
iframe.js
{
display: none;
}
iframe.unclickable
{
pointer-events: none;
}
</style>
<script>
$(document).ready(function()
{
$('#iframeID1').on('load', function()
{
$('#iframeID1').contents().find('a[href!="javascript:void(0)"]').filter('a[target!="_blank"]').filter('a[target!="_top"]').filter('a[target!="_parent"]').on('click', function()
{
$('#iframeID1').addClass('js');
$('#iframeID2').removeClass('js');
});
$('#iframeID1').contents().find('#mySidenav').remove();
$('#iframeID1').removeClass('js');
$('#iframeID2').addClass('js');
$('#iframeID2').contents().find('html').html($('#iframeID1').contents().find('html').html());
});
});
</script>
</head>
<body>
<iframe id="iframeID1" height="800px" width="800px" src="https://www.w3schools.com/" class="js"></iframe>
<iframe id="iframeID2" height="800px" width="800px" src="https://www.w3schools.com/" class="js unclickable" ></iframe>
<script>

I need to load an html page inside a div in the following pseudo page:
<html>
<head></head>
<style>
body {
background-color: yellow;
}
</style>
<body>
<div style="display:none">
<html>
<head></head>
<style>
body {
background-color: blue;
}
</style>
<body>
<div style="display:none">
...
</div>
</body>
</html>
</div>
</body>
</html>
What naturally happens in this code is that the background will turn blue, as it is being changed in the middle of the page. Is there a way to isolate this div? So it would act similarly to an iframe. The content inside the div is stored in a variable, so I think I cannot use a frame, as the html code is not stored in a file to use it as a source.
Thank you!
This is just wrong.
An HTML document can only have one html tag and one body tag, otherwise it will be an invalid document, browsers won't allow it.
If you load an iframe, instead, it will have his own #document and it's fine.
You can not load a Site into a Site without an Iframe due to security risks.
The only thing you can do, is to load the external Site with a serverside script like php, cut of the head with regexp and send the rest to your site into your div.
We are using the simplemodal jquery plugin to host an iframe as the contents of the dialog. Upon closing the dialog, simplemodal removes the dialog content (an iframe wrapped in a div) from the document and then adds it back to the document.
The following markup demonstrates the problem while taking simplemodal out of the equation. I only mention simplemodal in this post for context as to why the iframe is removed and re-added.
How do I prevent the Iframe from reloading it's contents when it is re-added to the document?
Any help would be greatly appreciated!

I think that it is not possible if you use remove().
But maybe you could try other way, like changing its size, display:none, opacity:0, visibility:hidden or some other.
Have you tried detach()?. In the jQuery documentation says:
To remove the elements without removing data and events, use .detach() instead.
Rather than creating the modal from an element that's on the page, you can create it from an HTML string. That way, the plugin doesn't have to remove the iframe from the document, put it in the modal, then move it back after the modal closes.
The only trick I could think to do is to add the iframe to the body element and set it to display:none; position:absolute;. Then insert a placeholder element into the simplemodal, and when the modal is shown make the iframe visible and change its position to that of the placeholder (also matching height and width).
It may require fiddling with the z-index and such as well, but it would mean you won't have to append/prepend/otherwise alter the DOM, thus preventing a reload.
I could otherwise recommend you using div + AJAX. Works much better for me then iframe and you don't have to style both the iframe and the secondary page. I don't know if this suits your need, but I recommend you checking up on it at least.
That might not fix your problem but worth a try.. you don't need to call remove before prependTo.
prependTo will effectively take it out of its current spot and re-attach it somewhere else in the DOM. It doesn't copy it so you don't need to "remove" the original
Maybe that'll prevent the iframe from reloading.
Though, I do agree with #Ryuu's answer, don't bother with iframes at all is the best option.
