history.replaceState() example?
JavascriptAjaxHtmlJavascript Problem Overview
Can any one give a working example for history.replaceState? This is what w3.org says:
> history.replaceState(data, title [, url ] )
>
> Updates the current entry in the session history to have the given data, title, and, if provided and not null, URL.
Update
This works perfectly:
history.replaceState( {} , 'foo', '/foo' );
URL is changing, but title is not changing. Is that a bug or am I missing something? Tested on latest Chrome.
Javascript Solutions
Solution 1 - Javascript
Indeed this is a bug, although intentional for 2 years now.
The problem lies with some unclear specs and the complexity when document.title
and back/forward are involved.
See bug reference on Webkit and Mozilla. Also Opera on the introduction of History API said it wasn't using the title parameter and probably still doesn't.
> Currently the 2nd argument of pushState and replaceState — the title > of the history entry — isn't used in Opera's implementation, but may > be one day.
Potential solution
The only way I see is to alter the title element and use pushState instead:
document.getElementsByTagName('title')[0].innerHTML = 'bar';
window.history.pushState( {} , 'bar', '/bar' );
Solution 2 - Javascript
Here is a minimal, contrived example.
console.log( window.location.href ); // whatever your current location href is
window.history.replaceState( {} , 'foo', '/foo' );
console.log( window.location.href ); // oh, hey, it replaced the path with /foo
There is more to replaceState()
but I don't know what exactly it is that you want to do with it.
Solution 3 - Javascript
history.pushState
pushes the current page state onto the history stack, and changes the URL in the address bar. So, when you go back, that state (the object you passed) are returned to you.
Currently, that is all it does. Any other page action, such as displaying the new page or changing the page title, must be done by you.
The W3C spec you link is just a draft, and browser may implement it differently. Firefox, for example, ignores the title
parameter completely.
Here is a simple example of pushState
that I use on my website.
(function($){
// Use AJAX to load the page, and change the title
function loadPage(sel, p){
$(sel).load(p + ' #content', function(){
document.title = $('#pageData').data('title');
});
}
// When a link is clicked, use AJAX to load that page
// but use pushState to change the URL bar
$(document).on('click', 'a', function(e){
e.preventDefault();
history.pushState({page: this.href}, '', this.href);
loadPage('#frontPage', this.href);
});
// This event is triggered when you visit a page in the history
// like when yu push the "back" button
$(window).on('popstate', function(e){
loadPage('#frontPage', location.pathname);
console.log(e.originalEvent.state);
});
}(jQuery));
Solution 4 - Javascript
look at the example
window.history.replaceState({
foo: 'bar'
}, 'Nice URL Title', '/nice_url');
window.onpopstate = function (e) {
if (typeof e.state == "object" && e.state.foo == "bar") {
alert("Blah blah blah");
}
};
window.history.go(-1);
and search location.hash
;
Solution 5 - Javascript
The second argument Title does not mean Title of the page - It is more of a definition/information for the state of that page
But we can still change the title using onpopstate event, and passing the title name not from the second argument, but as an attribute from the first parameter passed as object

Solution 6 - Javascript
According to MDN History doc
There is clearly said that second argument is for future used not for now. You are right that second argument is deal with web-page title but currently it's ignored by all major browser.
Firefox currently ignores this parameter, although it may use it in the future. Passing the empty string here should be safe against future changes to the method. Alternatively, you could pass a short title for the state to which you're moving.

I really wanted to respond to @Sev's answer.
Sev is right, there is a bug inside the window.history.replaceState
> To fix this simply rewrite the constructor to set the title manually.
var replaceState_tmp = window.history.replaceState.constructor;
window.history.replaceState.constructor = function(obj, title, url){
var title_ = document.getElementsByTagName('title')[0];
if(title_ != undefined){
title_.innerHTML = title;
}else{
var title__ = document.createElement('title');
title__.innerHTML = title;
var head_ = document.getElementsByTagName('head')[0];
if(head_ != undefined){
head_.appendChild(title__);
}else{
var head__ = document.createElement('head');
document.documentElement.appendChild(head__);
head__.appendChild(title__);
}
}
replaceState_tmp(obj,title, url);
}
Solution 8 - Javascript
Suppose https://www.mozilla.org/foo.html executes the following JavaScript:
const stateObj = { foo: 'bar' };
history.pushState(stateObj, '', 'bar.html');
This will cause the URL bar to display https://www.mozilla.org/bar2.html, but won't cause the browser to load bar2.html or even check that bar2.html exists.
Solution 9 - Javascript
Consider this as URL: http://localhost:4200/inspections/report-details/60c88e4e76b14c00193f5bef
let reportId = '60c88e4e76b14c00193f5bef', scope = "dynamic"
window.history.replaceState(null, null, `inspections/report-details/${reportId}?damagePart=` + scope );
This will yield output
http://localhost:4200/inspections/report-details/60c88e4e76b14c00193f5bef?damagePart=dynamic/
