I have add this code in the body tag. the web page keeps on refreshing like a loop.
<body onload="window.location.reload()">
I tried searching for a Javascript code or for a condition that will make it stop. I found a ways to do it but when I test it, they are not working.
I'm sorry but it is not possible to refresh the page 1 time once the page is completely loaded.
I want only once load page when i open the page. Can any one please tell me
You could do something like:
When the page loads, read the URL.
If there is no fragment identifier (e.g., #reloaded), add the fragment identifier and reload the page.
If there is a fragment identifier (e.g., #reloaded), don't reload.
This isn't necessarily a fool-proof technique, but might serve your purposes.
window.onload = function() {
if (window.location.hash !== "reloaded") {
window.location = window.location + "#reloaded";
window.location.reload();
}
}

First I used include('pageName.php'); for every page I wanted to load.
Now I decided to rewrite everything and to load a page in a <div id="page_content"></div> with the jQuery function: $('#page_content').load(pageurl, {access:true});
I hope this is the best practice. Because I want to reduce load time on my web application by not refreshing the whole website with all CSS and JS files but just to refresh content when clicked on a new page.
Currently I am using the following function to load pages into the division and to pushState to history:
//Dynload pages
$("a[rel='dynload']").click(function(e) {
e.preventDefault();
var page = $(this).attr("page");
var pageurl = "pages/" + page + ".php";
$('#page_content').load(pageurl, {access:true});
if(pageurl!=window.location){
window.history.pushState({path:pageurl},'',page);
}
//stop refreshing to the page given in
return false;
});
This works perfectly.
I have this button that triggers this function and gives for attribute page="index_content" . The function will load this page to the division and the state is being pushed into the history.
However. We get an url something like this: https://mywebsite.com/index_content
The problem is, when I load this specific URL into my browser I get : "Page not found" ofcourse, because it is trying to search for the index_content folder which does not exist.
Is there a way to check the url by my PHP/jQuery script and to load the correct page into the division? If not, how can I solve this for a generic case.
When I add a new page, I want to spend no- to very less time on the pageswitcher function.
In that way I can also handle non-existing pages.
Thanks in advance!
I have to do some kind of operation on the page refresh or reload. that is when I hit next page or Filter or refresh on the grid. I need to show some confirmation box over this Events.
is there any event which can tell you page is doing filer? refresh or paging? using javascript?
Thanks
If it is refreshing (or the user is leaving the website/closing the browser), window.onunload will fire.
// From MDN
window.onunload = unloadPage;
function unloadPage()
{
alert("unload event detected!");
}
https://developer.mozilla.org/en/DOM/window.onunload
If you just want a confirmation box to allow them to stay, use this:
window.onbeforeunload = function() {
return "Are you sure you want to navigate away?";
}
You can create a hidden field and set its value on first page load. When the page is loaded again, you can check the hidden field. If it's empty then the page is loaded for the first time, else it's refreshed. Some thing like this:
HTML
<body onLoad="CheckPageLoad();">
<input type="hidden" name="visit" id="visit" value="" />
</body>
JS
function CheckPageLoad() {
if (document.getElementById("visit").value == "") {
// This is a fresh page load
document.getElementById("visit").value = "1";
}
else {
// This is a page refresh
}
}
There are some clarification notes on wrestling with this I think are critical.
First, the refresh/hidden field system works on the beginning of the new page copy and after, not on leaving the first page copy.
From my research of this method and a few others, there is no way, primarily due to privacy standards, to detect a refresh of a page during unload or earlier. only after the load of the new page and later.
I had a similar issue request, but basically it was terminate session on exit of page, and while looking through that, found that a browser treats a reload/refresh as two distinct pieces:
close the current window (fires onbeforeunload and onunload js events).
request the page as if you never had it. Session on server of course has no issue, but no querystring changes/added values to the page's last used url.
These happen in just that order as well. Only a custom or non standard browser will behave differently.

My url format is like :
http://domain.in/home
http://domain.in/books/notes
http://domain.in/books/notes/copy
I've called a javascript function on window.load to check if the url has changed or not.
If the url has been changed then code is executed else it will return and checks again after 5 sec.
My code is :
window.onload = function(){
setInterval(function(){
page_open();
}, 5000);
};
function page_open(){
var pages=unescape(location.href);
pages=pages.substr( pages.lastIndexOf("studysquare.in/") + 15 );
// gives book if url is http://studysquare.in/book
//alert("pages"+pages+"\n\n recent"+recent);
if (pages==recent) { return; }
recent=pages;
alert("Reached down now the code will execute.");
}
The problem now is : when the url is like :
http://domain.in/book
Single level deep, then everything works fine. But when the url is like
http://domain.in/book/copy or http://domain.in/book/copy/notes
Then nothing works.....
Any help to check 3 level deep url change in javascript every 5 sec ? :)
Hi sorry I forgot to tell that... I've .htaccess file which doesnt allow to navigate the page when any length url after the domain.in/ is written.... that means only single page remains open and not affected by the url change...
When the user changes the URL, the browser unloads the entire page they're currently on (including your javascript, hence it stops running) and then loads the next page. No javascript is able to run across page changes. You can't monitor a change in the URL like you're doing if they're navigating to another page.
The best way to catch a change in the URL is to add an onUnload event to the body object to fire your javascript when the browser unloads the page just before starting to load the new page the user has requested -- but I'm not sure that's going to help achieve your goal of tracking their recent page views (if that's what you're looking to do).
Sounds like a history plugin such as jQuery address would help you a lot.
It lets you handle the event when the URL is changed, so you can load in new content as required.
My page runs on php for no js-users. For users with javascript on I load all content dynamic fromt the index in combination with the hashchangevent. So the links all look like www.page.com/#page.php, with a # before it. If the user types it in that way every thing works like charm and the content is being loaded over the index.php
But if a user would enter www.page.com/page.php the page of course ends up on the php page and the dynamic page will of course not work any more except the user will hit the index page and go on navigate from that. So that's not a cool way.
My Question:
How can I redirect user from:
www.page.com/page.php
to
www.page.com/#page.php
when they typed in www.page.com/page.php in the Browser
Of course only with javascript. The Page should work without javascript on normally with php.
Thank you.
When the page loads, change the window.location to the desired URL by deconstructing and reassembling the URI. Unfortunately, you'll have to include this on every page (i.e., page.php) on which you'd like the redirect to happen.
$(document).ready(function () {
// Insert the pathname after the hash, but skip the leading '`'
window.location = "/#" + document.location.pathname.slice(1);
});
It's slightly less clean, but you could also remove the window.location bit from .ready() entirely. This would effect an small performance improvement.
If you want the hash-redirect to affect only the last element of the current path, use the code below, instead.
window.location = "./#" + document.location.pathname.split('/').pop();
I have a scenario to refresh the browser after the page is loaded for first time or one time.
Because the data is not showing properly when the pages is loaded,and when i refresh the browser it is showing.I don't know the reason.
Many Thanks
So you only want the browser to refresh once? Do something like this.
window.onload = function(){
if(!document.location.hash){
window.location = "#loaded";
}
}
or jquery
$(document).ready(function(){
if(document.location.hash){
window.location = "#loaded";
}
});
But in all honesty this is just a temporary solution. As much as you try to cover it up with quick fixes. I guarantee it will come back to haunt you. Well written and structured code will last a lifetime and can always be reused on future projects.
Invariably, you're going to have to use some JavaScript. What you want is for your refresh code to run when the page is completely loaded. You could use the HTML onload event, but there are problems with this (e.g. it will fire before any images are loaded). I would suggest using JQuery's ready() event, if you want to be sure it fires after the entire page is loaded.
Example:
// NOTE: This will only work with JQuery loaded.
$(document).ready(function(){
location.reload(true);
});
Making this only fire on the first page load is a bit more tricky. You could add an anchor suffix to the URL to keep track of whether you've refreshed the page yet or not, and then only refresh if it is not present in the URL:
$(document).ready(function(){
if(location.hash != "#")
{
// Set the URL to whatever it was plus "#".
// (The page will NOT automatically reload.)
location = "#";
// Reload the page.
location.reload(true);
}
});
Alternatively, you could use the query string, since this will automatically refresh the page when changed:
$(document).ready(function(){
var marker = 'r'; // 'r' is for "refreshed"
if(location.search != "?"+marker)
{
// Set the URL to whatever it was plus "?r".
// (This will automatically force a page reload.)
location = "?"+marker;
}
});
Caveat: With either of these samples, if your user bookmarks the page after the "#" or "?r" tag has been added to the URL, the page won't refresh when they revisit the page. If you want it to be bulletproof, you might have to use a cookie instead.
