I am able to redirect/replace the url from the below code
function replceUrl(){
window.location.assign("https://www.example.com");
event.preventDefault();
}
After replacing the url, I want to stop page reload. I have added event.preventDefault(), but the page still reloads.
How to prevent page reload after replacing the url is the challenge
event.preventDefault() won't help you there, its purpose is to prevent the default behavior of the event that fired the function.
You won't be able to change the URL without reloading the page unless you use History API or window.location.hash
History API will let you change the last URL segment without reloading the page with this code: history.pushState({some: 'data'}, "New title", "new-url-segment") while window.location.hash = 'something' will let you change the URL fragment.
Note that the URL fragment's original purpose is to create links that scrolls to a specific id in the page once it's loaded.

I have a 3 step signup process where each step is shown on the page using javascript without a page refresh. What I am trying to do now is add a back reference to what step the user was on so if they click the browser back button they will not lose all of their progress.
So for example, as the user navigates from Step 2 to Step 3 the URL stays at www.example.com. The user then clicks the browser back button. The URL should now be www.example.com?step-2.
I'm thinking that I will somehow need to use the History API to accomplish this but if I use window.history.pushState(null, null, 'www.example.com?step-2'), the current URL would be changed as well.
How would I accomplish adding to the history without changing the current URL?
If your objective is to not change the URL, but to still allow back and forth history state changes, your best bet would be to utilize the window's hashchange event listener. This would of course utilize hash references within the URL, but the base URL won't change:
function locationHashChanged() {
if (location.hash === '#step-2') {
// Do something here
}
}
window.onhashchange = locationHashChanged;
For further info on this, refer to official documentation:

i am learning on how to use pushState to navigate url to the exact placement. When click on the button, url changes to 'upload' but does not navigate to the url page. This is what i tried;
home.html
<button onclick="loadUpload()">Upload Page</button>
<div id="upload"></div>
<script>
function loadUpload(){
history.pushState({}, "", "/upload/");
document.getElementById("upload");
}
</script>
The entire point of pushState is that it doesn't trigger navigation. It is a mechanism for saying "I am changing the state of the DOM using JavaScript, the resulting state is the same as you would get if you visited this URL" (while making the back and forward navigation buttons built into the browser work).
If you want to navigate with JavaScript then assign a new value to location.href.
location.href = "/upload/"
However, since your JavaScript doesn't do anything except navigate, you should just be using a regular link for this in the first place:
Upload Page
I have a page where there is a form which is used to Add / Edit Addresses.
In the right section of the page, there is a saved address Which has Edit link and it gives call to the same page URL with adding a new parameter say "billingID.XXXXX".
After clicking on this link, page is re loaded with the default address data auto filled.
I need this to happen on the first time load. I tried triggering click event on this Edit link on load, but I suppose it is not allowed by jQuery.
What are the other options I have with jQuery / javascript to add this URL parameter on load of page.?
You could try the Javascript History API.
https://developer.mozilla.org/en-US/docs/Web/API/History_API
It depends on what you want to do, I didn't understand you quite clear.
If you need the page to be reloaded and show the page by url, you can get 'href' value by jquery and then call window.location = $('.mylink').attr('href') + '?billingID.XXXXX';.
If you just want to replace url in browser panel, you can use History API as Kahuna suggested. E.g. you can call
window.history.replaceState(null, document.title, window.location.path + '?helloworld=1');
but then you have to update the page contents by yourself, using JS and jQuery.
you can try this:
if(window.location.href == 'requestd page href'){//http://localhost/test/test.php
window.location.href += "?billingID.XXXXX";
}
I am creating a slideshow which is changing images with jQuery. When i change the image i also change page title and page url without reloading the page. I am changing url with:
window.history.pushState({path:url},'',curentImage[3]);
rightNav.click( function(){
imageArea.append(curentImage[2]);
title.text(curentImage[4]);
window.history.pushState({path:url},'',curentImage[3]);
});
If i click back on browser it changes the url to previous one, but doesn't load that page. How can i load page with previous url when i click browser back button?
I have just figured out the solution that helps in my case. I have added event listener for popstate which is redirecting me to the url i wan, some default url, or can be set to previous url.
window.addEventListener("popstate", function(e) {
window.location.href = defUrl;
});
jQuery(document).ready(function() {
});
or
window.onload = function () {
}
doesn't triggers when URL contents '#' character at end. Any idea to get through?
example: http://beta.something.com/user.php#
javascript onload never trigger on above url. how can i get it triggered?
Without further information it's hard to be sure, but I suspect you're already on the same page, so going to a "hashed" url won't actually reload the page and the onload function won't fire.
In other words, if on the page user.php you have a link like this: foo, clicking on it won't reload the page but just moves you to the top of the document and no onload event is triggered.
The ready and load events are only triggered when the page is first loaded. When you go to the same page with a bookmark added to the URL, the page is not reloaded, the browser just scrolls to the bookmark in the page.
An URL ending with just a hash character has an empty bookmark, so the browser scrolls to the top of the page.
