I'm having following problem. I have following code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Click Me test site</title>
</head>
<body>
Click Me
<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>
<script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script>
$(document).ready(function() {
var handler = function codeclick(event) {
var link_new = $('a').attr('co-target');
if (link_new) {
window.open(link_new, '_blank');
}
}
$('a').bind('click.codeclick', handler);
});
</script>
</body>
</html>
You can see it in action here
The expected behaviour on desktop is that the page in co-target attribute is opened in new tab/window and the one in href attribute is opened in current tab.
On internal mobile facebook browser it should open just the co-target attribute page (intended). But on Google mobile iOS app it opens the page in href attribute (unintended).
Does anyone encountered similar problem before and maybe have some clues what should I do to make it right? There is no need that the page in co-target has to open. I just want it that on both facebook and google app it open one of it, not different one in each.

I want to disable the browser's back button. I have tried some javascript codes to implement the same. But those codes didn't meet my requirements. It works in firefox but not working in chrome and edge. Sometimes it works all the three but randomly working and not working.
Can anybody share me the script disable the back button in all browsers without flaws like random behaviour.
Here I showed some scripts I have tried
history.pushState(null, null, window.location.href);
history.back();
window.onpopstate = () => history.forward();
history.pushState(null, null, location.href);
history.back();
history.forward();
window.onpopstate = function () { history.go(1); };
You can refer to the following code. I test the code sample in Edge, Chrome and Firefox, it works well.
Save this file as a.html for the first page:
<!DOCTYPE html>
<html>
<head>
<title>First Page</title>
<script type="text/javascript">
function preventBack() {
window.history.forward();
}
setTimeout("preventBack()", 0);
window.onunload = function () { null };
</script>
</head>
<body>
<h3>This is first page</h3>
Goto second Page
</body>
</html>
Save this file as b.html for the second page:
<!DOCTYPE html>
<html>
<head>
<title>
Blocking Back Button using javascript
</title>
</head>
<body>
<h3>This is second page</h3>
<p>
On this page, back button functionality is disabled.
</p>
</body>
</html>
Run a.html and click to navigate to b.html. Then click browser's back button on b.html, it won't navigate to a.html.
I have a question we must have seen many a time that when we are about to close the window and Just hover mouse over the cross on Browser Tab, a pop up appears asking for us to subscribe or highlighting some coupon. This Functionality is based on which feature of the browser, does it exploits some PHP code or some artificial intelligence.
It is run on client-side as everything that interact with user interface.
The example bellow shows how to do this with pure javascript (not tested with all browsers, but works well with Chrome)
<!DOCTYPE html>
<html>
<head>
<title>Page exit example</title>
<script type="text/javascript">
var showMessage = true;
window.onmouseout = function(){
if(showMessage){
showMessage = false;
document.getElementsByTagName('body')[0].innerHTML = "Dont leave yet!";
}
};
</script>
</head>
<body>
<h1>Hello world</h1>
</body>
</html>
I need to disable right click on a Anchor tag/hyperlink in page/popup open in iframe using javascript/jquery?
I have below code logic which works when I open page in iframe but not work when I open popup in Iframe by clicking on link within the Iframe page.
In below example when I right-click on Open Popup link its not allowing the right click but when I open popup by clicking Open Popup link it's not working for links in popup.
Any suggestions?
Below sample code snippet for reference -
TestPage.html
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<title>Test Page</title>
</head>
<body>
<iframe id="sampleIframe" src="PopupPage.html" width="400" height="150"></iframe>
<script language="javascript" type="text/javascript">
$('#sampleIframe').load(function() {
$('#sampleIframe').contents().find('a').each(function() {
$(this).on("contextmenu", function() {
return false;
});
});
});
</script>
</body>
</html>
PopupPage.html
<html>
<head>
<title>Popup Page</title>
</head>
<body>
You are on popup page.
Open Popup
<script language="javascript" type="text/javascript">
function openPopup() {
window.open("LinkPage.html", null,
"height=200,width=400,status=yes,toolbar=no,menubar=no,location=no");
}
</script>
</body>
</html>
LinkPage.html
<html>
<head>
<title>Link Page</title>
</head>
<body>
Goto Google
Goto Facebook
</body>
</html>
For this to work, you need to include your script to disable the links in the actual iFrame content.
To demonstrate, create a jsfiddle with this code (it will not let me save it to post a link)
This would be your "LinkPage.html"
HTML
Open Popup
JAVASCRIPT
function openPopup() {
window.open("http://jsfiddle.net/t45qvtap/1/show", null,
"height=200,width=400,status=yes,toolbar=no,menubar=no,location=no");
}
And you will see it working.
Just to explain further, this is the contents of the fiddle that the above code will open in an iFrame, this would be your "PopupPage.html"
HTML
This content is in an iframe
<div>
Goto Google
Goto Facebook
</div>
JAVASCRIPT
$('body').contents().find('a').each(function() {
$(this).on("contextmenu", function() {
return false;
});
});
In Javascript, I want to open my window.html file in a popup window. But it doesn't display any text. Just a blank page.
This is index.html:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
<script language="javascript">
var newwindow;
function popit(url){
newwindow = window.open(
url, '', "status=yes, height=500; width=500; resizeable=0");
}
</script>
</head>
<body>
CLICK ME!
</body>
</html>
window.html:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p>SAMPLE TEXT</p>
</body>
</html>
Why doesn't it display any text?
javascript:popit(window.html);
Replace with:
javascript:popit('window.html');
Your click handler code is syntactically incorrect:
CLICK ME!
Always, always have your developer console open to check for JavaScript errors! (edit — actually in this case there wouldn't have been an error; window.html would resolve to undefined probably! Still, keep the console open :-)
Also note that I used an "onclick" attribute instead of "href".
A GOOD working code with NO crashes.
Simple and what makes this code better is that you can use it in a JavaScript file separately and have it fairing to more then one file with the same popup size even though its different pages on popups.
Javascript
// Popup window code
function MyPopUp(url) {
popupWindow = window.open(
url,'popUpWindow','height=454,width=580,left=0,top=200,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes')
}
HTML
My PopUp
NOTE: You can also use this as onload in body for example <body onload="JavaScript:MyPopUp('MyDirectory/Page.html');"> and it will aslo work on onmouseover and others... though I do not advise this unless you want to piss off the clients visiting your page.
*Update: Ultimately I've decided that accomplishing exactly what I want here isn't possible due to the issues it poses to security. Kalle's answer below gives a solution that is closest to what I want to accomplish.
In order to solve my problem I've created scripts on both pages and will use a sort of push notification that is routed through the server in order for them to communicate.
Thanks for the help!! *
I have two pages. Both windows already exist independently. Page two has a function declared in JS.
I would like to be able to call the function in window two by clicking a link in window one.
Page 1:
<html>
<head>
<title>This is a title!</title>
</head>
<body style="background: lightblue">
Click Me!
</body>
Page 2:
<html>
<head>
<META HTTP-EQUIV="Window-target" CONTENT="my_target" />
<title>This is a title!</title>
<script type=text/javascript>
function clicked() {
alert('test');
}
</script>
</head>
<body style="background: lightblue">
</body>
Since it is on the same domain you can get this to work but would have to change the way you were doing it a little.
First off you would have to open it in a popup using this syntax rather than a new tab:
newwindow=window.open(url,'name','height=200,width=150');
and then you could simply call newwindow.clicked() after the popup is called.
update
just did a quick test and this will open it in a new tab. (sorry its been a while since I used the open function.
newwindow=window.open(url,'name');
Just noticed also that you should wait for the popup to load. So in my Example it would look a little something like this (with jQuery):
var newwindow = window.open('http://www.tylerbiscoe.com/vb/new.html');
$(newwindow).load(function(){
newwindow.clicked();
});
Ok, brand new answer. I hope this is what you were thinking. This is however, when you open page 2 from page 1.. So basically, page 1 would know who page 2 is..
Online example: http://kopli.pri.ee/stackoverflow/6832271.php
Page 1
<html>
<head>
<title>Page 1</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<style>
.ajaxlink {color: blue; cursor: pointer; border-bottom: 1px dotted blue;}
</style>
</head>
<body>
<span id="open_page_2" class="ajaxlink">Open new window</span>
<br>
<br>
Click Me!
<script>
$('#open_page_2').click(function(){
child = window.open('test2.php','page_2','width=600,height=600');
});
$('a[target=my_target]').click(function () {
child.SecondPageFunction();
return false;
});
</script>
</body>
</html>
Page 2
<html>
<head>
<title>Page 2</title>
</head>
<body>
<h1>Your seeing page 2!</h1>
<script>
function SecondPageFunction () {
alert('Second page action got triggered!');
}
</script>
</body>
</html>
The script must be a part of the page you're opening in the new window. You're absolutely correct about it being a security flaw if it was elsewise allowed.
You could add some query string argument that could be picked up onload by javascript in the page you are opening and call your function if the query string arg is present.
