I need some way to detect if site from some URL is framebreaker or not. I mean that Framebreaker - site which brake frame structure if it loaded in a frame.
If what you're asking is 'how do I prevent my web page from being viewed in a frame?' then here's the best solution currently known:
Use CSS to set the page's body to not display:
<style>
body { display : none ; }
</style>
Then only display the page if it's not in a frame:
<script>
if (self == top) {
//Not in a frame
document.getElementsByTagName("body")[0].style.display = 'block';
} else {
//In a frame. Redirect to the real page.
top.location = self.location;
}
</script>
Put the style in the <head> and the script in the <body>.
If you just wanted to detect if the page is being framed, but not do anything about it, all you need is the following javascript:
<script>
if(self == top) {
alert("Not in a frame");
} else {
alert("In a frame");
}
</script>
Don't know why you've tagged this as php, only javascript can do this...
if (top !== window) {
top.location.href = '/url/';
}

I currently use
<script src="jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
if (window.location.href.indexOf("Startseiteplayerrun") > -1) {
alert("You have the player open already !");
window.history.back();
} else {
//window.open("Startseiteplayerrun.html","_self");
link = document.createElement("a");
link.href = "Startseiteplayerrun.html";
//link.target = "_blank";
link.click()
;}});
</script><br>
home
to check whether the string "Startseiteplayerrun" is present in the url bar.
However,
this check only seems to happen after failing the first time
=> I'm able to open the frame once within itself:
Can this be mitigated ?
The purposeof this "if else" is to not allow another iframe,
if the urlbar contains "Startseiteplayerrun" ...
If the string won't check right away, check if framed
~FIN~
<script>
if ( window.location !== window.parent.location ) {
alert("You have the player open already !");
window.history.back();
} else {
// The page is not in an iframe
}
</script>
There is a angularjs application, I am working out of it. in my web page, I am getting application loaded in the iframe - I just want to know whether the ifame loaded or not. for that, I use:
//but i don't like this.
var myTimeout = function () {
setTimeout(function(){
if($('.ssueContentIframe').length > 0 ) {
penetrate();
return;
}
myTimeout();
}, 10000);
};
myTimeout();
in the iframe there is number of content keep loading and changing. But one of the event I would require to add in the element with class name of .ui-grid-icon-ok - how can I hear from document that the element existence - any one help me?
If there's no constraints CORS or XSS, you should be able to do something like the following.
var what = document.getElementById('what');
function checkIframeLoaded() {
try {
// Get a handle to the iframe element
var iframe = document.getElementById('iframe');
var iframeDoc = iframe.contentDocument || iframe.contentWindow.document;
what.appendChild(document.createTextNode("Checking...\n"));
// Check if loading is complete
if (iframeDoc.readyState == 'complete') {
afterLoading();
return;
}
} catch (err) {
alert(err);
}
// If we are here, it is not loaded. Set things up so we check the status again in 100 milliseconds
window.setTimeout(checkIframeLoaded, 100);
}
function afterLoading() {
what.appendChild(document.createTextNode("It loaded!\n"));
}
checkIframeLoaded();
iframe {
width: 100px;
height: 25px;
}
<iframe id="iframe" src="data:text/plain,"></iframe>
<pre id="what">Not loaded.</pre>
If there are any constraints (e.g. sandboxing, CORS, XSS, etc.), you'll get an alert dialog every 10th of a second with the error, and I hope you have the ability to click the checkbox to ignore them. :)
Note: This is a modified version of this other stack overflow answer, expanded to demonstrate errors.
this questions is related to an html file calling out different pages in different iframe tags. Is there a way, using JavaScript probably, to check if there was a connection issue to the page? If so, to try reloading this frame until the connection is established.
To be a bit clearer, if you have a look at the following link (http://tvgl.barzalou.com) (even if the content is in French, you will notice how different parts of the page load, and more often than not, loads correctly). But once in a while, during the weekend, a slight connection issue to the net arrives and for some reason, the frame gives out this ridiculous grey / light grey icon saying that there was a connection issue. Of course, when the page is manually reloaded, the frame comes back to life.
Please check the updated code that will check and reload the iframe after the max attempts have been reached...
<script language="javascript">
var attempts = 0;
var maxattempt = 10;
var intid=0;
$(function()
{
intid = setInterval(function()
{
$("iframe").each(function()
{
if(iframeHasContent($(this)))
{
//iframe has been successfully loaded
}
if(attempts < maxattempt)
{
attempts++;
}
else
{
clearInterval(intid);
checkAndReloadIFrames();
}
})
},1000);
})
function iframeHasContent($iframe)
{
if($iframe.contents().find("html body").children() > 0)
{
return true;
}
return false;
}
function checkAndReloadIFrames()
{
$("iframe").each(function()
{
//If the iframe is not loaded, reload the iframe by reapplying the current src attribute
if(!iframeHasContent($(this)))
{
//reload iframes if not loaded
var $iframe = $(this);
var src = $iframe.attr("src");
//code to prevent cache request and reload url
src += "?_" + new Date().getTime();
$iframe.attr("src",src);
}
});
}
</script>
You can schedule a code which will check whether the iframes are loaded properly or not
Consider a sample
<script language="javascript">
var attempts = 0;
var maxattempt = 10;
var intid=0;
$(function()
{
intid = setInterval(function()
{
$("iframe").each(function()
{
if(iframeHasContent($(this)))
{
//iframe has been successfully loaded
}
if(attempts < maxattempt)
{
attempts++;
}
else
{
clearInterval(intid);
}
})
},1000);
})
function iframeHasContent($iframe)
{
if($iframe.contents().find("html body").children() > 0)
{
return true;
}
return false;
}
</script>
This simple code snippet will check whether iframes in the document have been loaded properly or not. It will try this for 10 attempts then it will abort the checking.
When the checking is aborted, you can call iframeHasContent() for each iframe to shortlist the ones that have not been loaded and reload them if required.
If a website is loaded into an iframe, what code do I need to put on the child page of that iFrame to break out of the iFrame and load that page as the top document or reidrect to that page
Just found the code
<script>
if(window.top !== window.self){
window.top.location.href = "http://www.blah.com";
}
</script>
Even better code:
<style> html{display : none ; } </style>
<script>
if( self == top ) {
document.documentElement.style.display = 'block' ;
} else {
top.location = self.location ;
}
</script>
Code Example below:
<!DOCTYPE html>
<html lang="en">
<head>
blah
</head>
<body>
<iframe src="www.blah.com"></iframe>
</body>
</html>
What JQuery or javascript do I need to put on (in this example) www.blah.com so it breaks out of the iframe and www.blah.com is directly shown to the user?
What you're looking for is called a Framekiller
Here's the suggested implementation from that article:
<style> html{display : none ; } </style>
<script>
if( self == top ) {
document.documentElement.style.display = 'block' ;
} else {
top.location = self.location ;
}
</script>
This should work:-
<script type="text/javascript">
if (window!=top){top.location.href=location.href;}
</script>
window.top.location.href = "http://blah.com/";
As mentioned here (with a fuller explanation):
Redirect parent window from an iframe action
If you are using a link setting target="_top" attribute probably would do the job.
What's the best way to remove a page frame automatically?
I've used this type of code before:
<script language="JavaScript">
setTimeout ("changePage()", 3000);
function changePage() {
if (self.parent.frames.length != 0)
self.parent.location="http://www.example.com";
}
</script>
Do you mean if someone has put a frame around your content? If so, you need the following any where in your HTML page to jump out of the iframe:
<script type="text/javascript">
if (window.top.location != window.location) {
window.top.location = window.location;
}
</script>
Here's an alternative that's more generic in that it doesn't name the parent URL, nor use the separate function call:
// is the current page at the top of the browser window hierarchy?
if (top.location != self.location)
{
// it isn't, so force this page to be at
// the top of the hierarchy, in its own window
top.location = self.location
}
Do it this way if you want the frame-breaking step to not appear in the history
if ( self.location !== top.location )
{
top.location.replace( self.location );
}
