Without clicking/touching on anywhere inside page when click browser back button, navigation should be disable.
Below implementation only work when click inside page.
history.pushState(null, null, window.location.href);
history.back();
window.onpopstate = () =>{ // not getting activate without clicking inside page
console.warn('DISABLE BROWSER NAVIGATION');
history.forward();
}
one of the best way is to open your application in a popup without controls but again depending upon your requirement this may not be applicable. Hope this helps. Something like below
function openPopup(){
var pathname = (window.location.pathname);
window.open(pathname+'openpagePopup.html','','width=800,height=450,toolbar=no, menubar=no,scrollbars=no,resizable=no,dependent,screenx=80,screeny=80,left=80,top=20,scrollbars=no');
return false;
}
The otherways are not trustworthy like you can show user an alert, but can not disable the back button, as per my knowledge. If you do the below make sure you check browser compatibility.
window.onbeforeunload = function() {
return "Write something here";
};
Update : I found there is a way to handle the page history. Incase that works, I have never tried, here is a link
JS - window.history - Delete a state

I disabled browser back button using the following code on load of page
history.pushState(null, null, location.href);
window.onpopstate = function () {
history.go(1);
};
Code is working fine.I am not able to proceed for previous pages. But forward button is also disabled. I have to enable forward button on the page.
You are forcing to update url manually by using history.pushState. If you use history.pushState, it clears forward state's history.
Hence window.history.forward() returns undefined. So you cannot go to forward direction.
Kindly use warning instead of disabling back button,
window.onbeforeunload = function() {
return "some text"
};
Been doing some research, is there any way to just reload the current page on user clicking the browser back button or forward? For SPA.
I know it is not recommended to restrict users from using their browser buttons and probably not much control of them either.
I was looking into something like this:
#HostListener('window:beforeunload', ['$event'])
onPopState(event) {
console.log("Back Button detected!");
window.history.forward();
}
Update: This is closer to what I want to achieve, but if the user spams the back button, he can potentially get back to a previous screen in SPA. (I am not using { skipLocationChange: true } so that may resolve that issue.
<script>
history.pushState(null, null, location.href);
window.onpopstate = function (event) {
history.go(1);
};
</script>
I have a site where if a user navigates to a certain page then he gets a dialog notification depending on some condition on the page. The user can navigate to other pages from this page and of course can press the back button on those pages to navigate back to this page.
I'd like to detect if the user arrives via the back button to this page, so the dialog notification is not shown again (because the user has already seen it).
Is there a way to detect this reliably?
MDN list of window events
Your best possibility may be window.onpageshow = function(){};
An event handler property for pageshow events on the window.
window.onpageshow = function(event) {
if (event.persisted) {
alert("From back / forward cache.");
}
};
Input trick is not longer working. Here's the solution I use:
if (window.performance && window.performance.navigation.type === window.performance.navigation.TYPE_BACK_FORWARD) {
alert('Got here using the browser "Back" or "Forward" button.');
}
The best (although not TREMENDOUSLY reliable) way is to use the Javascript history object. You can look at the history.previous page to see if it's the next in the series. Not a great solution, but maybe the only way to figure it out.
I like use a value in an input field for this:-
<input type="hidden" id="fromHistory" value="" />
<script type="text/javascript">
if (document.getElementById('fromHistory').value == '') {
document.getElementById('fromHistory').value = 'fromHistory');
alert('Arrived here normally');
} else {
console.log('Arrived here from history, e.g. back or forward button');
}
</script>
This works because the browser repopulates the value of the field with the one the javascript puts in there if it navigates back to it from history :-)
I have a application where i have disabled the back button of IE8 by using the following code.
window.history.forward();
function noBack() {
window.history.forward();
}
I know this code takes the page back and again moves the page forward. i have called a function onload of the page which makes a textbox read only. i have used the following code to make it read only.
$("#IDofTheTextBox").attr('readonly',true);
but if i select the textbox and try to edit by pressing "BackSpace" button, IE back button is getting invoked and the textbox which was readonly is not readonly anymore. Can anyone help me how to solve this issue?
The answer is simply "NO"
If you're trying to prevent the user from losing their work, try something like:
window.onbeforeunload = function() { return "Are you sure want to leave this page?."; };
function changeHashOnLoad() {
window.location.href += "#";
setTimeout("changeHashAgain()", "50");
}
function changeHashAgain() {
window.location.href += "1";
}
var storedHash = window.location.hash;
window.setInterval(function () {
if (window.location.hash != storedHash) {
window.location.hash = storedHash;
}
}, 50);
You add the above javascript functions in the js file and onload call the function changeHashOnLoad().
its working fine in IE8. i just tested it.
I dont know what your page is trying to do... but this is what we do:
We have an assessment where we do not want the browser buttons enabled... because we run ajax/logic when the user hits next/back etc (to determine what to display next based on their inputs). Back and forward buttons can muddy that process up.
So..... we have users open our assessments in A NEW WINDOW so the back button is already disabled...(there is no prior history in a new window). Then, Our next/back buttons use window.location.replace(url); This will prevent a history item from being created. Therefore, the back/forward buttons are never enabled and they must use the next/prev buttons to navigate our tool.
I would not try to muck with the buttons outside of something like the example I provided.
I am trying to handle browser back button event but i could not find any solution.
I want to ask user if he clicks on browser back button using "confirm box" if he chooses ok i have to allow back button action else i have to stop back button action.
Can any one help me in implementing this.
Warn/confirm User if Back button is Pressed is as below.
window.onbeforeunload = function() { return "Your work will be lost."; };
You can get more information using below mentioned links.
Disable Back Button in Browser using JavaScript
I hope this will help to you.
You can also add hash when page is loading:
location.hash = "noBack";
Then just handle location hash change to add another hash:
$(window).on('hashchange', function() {
location.hash = "noBack";
});
That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.
