How to disable the back button in the browser without going back? Below is the way that i have tried.
<html>
<head>
<script>
window.onload = function(){
window.history.forward();
};
</script>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
the best thing you can do is:
window.onbeforeunload = function() { return "your message here"; };
A workaround to "disable" the back button is create a page that redirects you to the page you want to show after a little time.
For example with this code for the first page:
<html>
<head>
<script type="text/javascript">
setInterval(function(){
window.location.href='secondPage.html';
},50);
</script>
</head>
<body>
</body>
</html>
If the user press the back button, the previous page will reopen the desired page.
However, remember that users will hate you for that.

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.
Essentially, all I want to do is open an external web page after the current page is loaded via java script.
open my page -> javascript tells browser to open external page -> external page being loaded into the broser
How may I accomplish this?
you may use this
<html>
<head>
<script type="text/javascript">
function load()
{
window.location.href = "http://externalpage.com";
}
</script>
</head>
<body onload="load()">
<h1>Hello World!</h1>
</body>
</html>
<html>
<head>
<script type="text/javascript">
function load()
{
window.location.href = "http://externalpage.com";
}
</script>
</head>
<body onload="load()">
<h1>Hello World!</h1>
</body>
</html>
Hope it should be window.location. Check the code.
Technically you can:
location.href = "http://example.net/";
… but you should perform an HTTP redirect instead as that is more reliable, faster and better food for search engines.
You can also use the "open" method to open the source file or url on a new window.
window.open("anyfile.*");
or
window.open("http://anylocation.com");
Hi please try this code for page loading time we will redirect whatever u configured the urls.
<!DOCTYPE html>
<html>
<head>
<script>
function myFunction() {
window.open('https://google.com');
}
</script>
</head>
<body onload="myFunction()">
</body>
</html>
<body>
<script>
document.body.innerHTML += 'Link';
document.getElementById("link").click();
</script>
<body>
I have a page for redirect purpose, I want to redirect user to another page once it hits this page:
<!DOCTYPE html>
<html>
<head>
<title>Open App</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
alert("test"); //this shows up.
$('#openApp').click(); //this button is not clicked.
});
</script>
</head>
<body>
redirect
</body>
</html>
I want the redirect happen once this page is load. But the click function is not fired. I have to click the link by myself to redirect to google.com.
I normally wouldn't give you an alternative as an answer, but looking at your comments, it looks like you're just trying to redirect.
You can use window.location.replace('http://www.google.com'); for that.
$(document).ready(function () {
window.location.replace('http://www.google.com');
});
See also, this answer.
It's not possible to trigger a click event without any user interaction. In other words, if the function being called wasn't called from a user interaction, the click event will not get triggered.
In your case, simply update the window.location attribute:
window.location = 'http://www.google.com';
try this fiddle mate, added script is
$(document).ready(function () {
//this shows up.
$('#openApp')[0].click(); //this button is not clicked.
});
I want to open hash #home automatically on page load. I tried
<body onload=window.location='#home'>
JS way:
<html>
<head>
<script type="text/javascript">
function load()
{
window.location.href = "#home";
}
</script>
</head>
<body onload="load()">
<h1>Hello World!</h1>
</body>
</html>
And html redirect
<meta http-equiv="refresh" content="0; url=#home" />
All ways are too slow (about 2-3 sec. to redirect after page load). Is there any better (faster) way to automatically open #home on page load?
Do this:
<body onload="window.location.hash='home'">
I think this is the fastest way.
To redirect to the specified tag, set the id of any div or control with "home".
<html>
<head>
<script type="text/javascript">
function load()
{
window.location.href = "#home";
}
</script>
</head>
<body onload="load()">
<h1>Hello World!</h1>
<div id="home">Some content</div>
</body>
</html>
I found best solution. There is no load time. It check hash and if there is no hash (first page load) open hash tab #home. Example:
<script type="text/javascript">
$(document).ready(function(){
var x = location.hash.replace("#","");
if (x==="")
{
window.location.href = "#home";
}
});
</script>
Really i tried many ways but this is the best and fastest.
*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.
