I am making a redirect using window.location.href to Listing view after an Item is added to DB after successful CREATE operation.
But what it does, it simply fetches old page (not showing the newly added item) that was previously in borwser's cache.
I want it to fetch every think from server, just like we use true parameter in document.location.reload(true) to load a fresh copy of page from server.
You can use this:
window.location.href = "http://www.mywebsite.com/products?t="+ (new Date().getTime());
Or:
window.location.href = "http://www.mywebsite.com/products?t="+ Math.random();

I am designing a HTML page, and I would like to send a simple message (or trigger some action) when the user intentionally request updating (update button on the web browser, pressing F5... or whatever any other manual method that could exist) of the HTML file.
Something like:
window.onmanualupdaterequest = alert("You requested update");
Or whatever the correct procedure could be.
How could I do this?
Further notes:
I have tried the window.onbeforeunload function (example), but it does not exactly solve the problem (I would say it has not the same behavior as user request).
I would like to ignore the autoupdate case (like in setInterval or similar functions or scripts) from the manual update case. This question is about the manual one.
The classical Android swipe-down update method for a web page is considered here as a manual update method.
My idea would be to use the sessionStorage to save the window.location.href on pageload. If the user reloads the page the stored location should match the current url:
window.addEventListener('load', function () {
const lastUrl = sessionStorage.getItem('lastUrl');
if(lastUrl && lastUrl === window.location.href) {
alert("You requested update");
}
sessionStorage.setItem('lastUrl', window.location.href);
});
I'm attempting to remove a url parameter status from the url but in the following alert, the parameter is still there.
var addressurl = location.href.replace(separator + "status=([^&]$|[^&]*)/i", "");
alert(addressurl);
location.href= addressurl;
How do i solve?
You are confusing regex with strings.
It should be:
var addressurl = location.href.replace(separator, '').replace(/status=([^&]$|[^&]*)/i", "");
Javascript context in web pages are to the page you are working on.
When you reload, redirect or move to any other page, javascript changes done in previous page will not be there. This has to be handled from server side.
Refresh repeats the last request to the server, which is going to ignore your javascript changes. Instead navigate to the new url with window.location = addressurl;
I can use location.reload(true) to refresh the page and refetch the page. I want to redirect the user to a new URL and clear the cache.
More specifically, I have a "Clear all cookies" button that redirects the user to the homepage after being clicked. I want the homepage to be refreshed.
Do something like:
var loc = window.location.href; // or a new URL
window.location.href = loc + '?n=' + new Date().getTime(); // random number
EDIT: The only option for reloading static resources (see comment below) would be to append the random number to their URLs server-side by listening for the 'n' query string.
Sorry, but you can't clear the cache with Javascript.
I have a script that runs on some pages. The problem is that I attach the script on the page load, but all links on the page make requests and change the contents from the response. (The url's hash changes)
I need a way to check when the "page" is finished loading to add my scripts.
The problem:
somesite.com/home (event load is fired)
*user clicks a link*
somesite.com/home#profile (event load isn't fired, the page is
already loaded, but the contents are
being changed through ajax calls)
How can I do that? I'm thinking on adding a watcher that will check the page all the time and call the corresponding script.
How can I check if the page is sending a request and execute something when the request ends? (I guess it's possible since Firebug does that)
You could use setInterval, and check every 500 ms for changes in the location hash:
var oldHash = '';
setInterval(function(){
var newHash = location.hash;
if(oldHash != newHash){
oldHash = newHash;
// do something
}
}, 500);
In my web app, a user can click an item in a list, and I modify the url in their browser:
<li>Horse</li>
<li>Cow</li>
<li>Goat</li>
function onListItemClicked() {
window.location.hash = item.name;
}
this will change the url in the user's browser to:
www.example.com#Horse
www.example.com#Cow
www.example.com#Goat
if I'm reading correctly, we can't get the # part of the url servlet-side, right? If the user copies and pastes the url from their browser to friend, it would be cool if I could generate the page already initialized with the item they clicked.
It looks like this is not possible, I'll have to load the appropriate page via javascript after the document finishes loading,
Thanks
No, you can't do this from the server side on. URL fragments are purely client side. You need to do this in the client side during page load.
window.onload = function() {
var hash = window.location.hash;
// Do your business thing here based on the hash.
}
