Is it possible to append something into another route ?
For example,
I had an input in Order page and once it submits, it will append the data in Kitchen Page and refreshes the content without refreshing the whole page itself.
EDIT: Can someone give an example syntax ?

In my last post I was asking how to let the user decide on pagination numbers. I thought I had figured it out, but now it appears I messed something up, as the pagination seems to work but as soon as you go to the next page, it's blank and the number of pages is set to 1.
importeren.blade.php page (this is where the data of the imported file(s) is shown). This also has the pagination links for Laravel, I feel the error could be within there but I am not 100% sure.
DataController index method that loads the amount of pages as specified by the user:
Here is a short clip displaying what happens once I enter the results for the amount of records to be displayed per page.
I do not know what I am missing, but if anyone could help out that'd be amazing.
You should append your parameter to each pagination link.
To do so you can use {{$datas->appends(['paginate_number' => request('paginate_number')])->links()}}
I will suggest to change method="POST" to method="GET" in the form.
First try as a static like this
$datas = Data::paginate(10);
If it works then you have to change $request->input('paginate_number')
I am developing a website in Laravel 5, It has a Jobs page where data loaded through ajax which have many filters. When I open a link and come back to the previous page (Jobs page) by clicking the browser back button, it showing me Json data on the browser window instead of loading the whole page.
Kindly let me know how to solve this issue.
If you're using the same url for the JSON request as you are for the html request then the browser will simply be returning the last response to that url which will be the JSON data.
There are a few different ways to overcome this but essentially you'll have to modify your url so that the browser treats them as different responses.
One way would be to append a query string value to the ajax call e.g. ?json.
A slightly more complex yet more flexible approach would be to create separate controllers for your views and JSON data and then prefix your JSON routes with something like /api e.g.
For the view
example.com/jobs -> Pages/JobsController#index
For the json data
example.com/api/jobs -> Api/JobsController#index
I'm new to Django so apologies if this is a really stupid question but I'm trying to get a table to reload database values and when I open the page in a browser it loads ok initially but when it tries to reload nothing appears to happen. When I look in the network section of inspect element I can see repeated 404 page not found errors. I've been searching stack exchange etc. for a few days and I've tried various types of quotes etc. round the url tag but no joy. I'd really appreciate any help anyone can give me on this. I'm using python 3 and django2.

The problem is a simple typo: you have a space between the { and the % in your url tag. This is causing Django to not recognise it as a tag, so the Ajax is using the literal string "{ % url ... }" as the URL which explains the mess you see in the terminal. Remove the space.
(Note, you still might not get the result you expect, since your Ajax function returns a complete HTML page but you are inserting that result inside a div in an existing page; you probably either want to replace the whole page or return a template fragment from your view.)
I'm using a script from https://css-tricks.com/rethinking-dynamic-page-replacing-content/ to partially refresh pages.
But the title of the page remains unchanged and is thus confusing to users.
Is there a sensible solution to amend that script?
You can change page title as you load pages in ajax with
document.title='sometitle'
I am new to ajax and i wanted to know if we can load a complete new page and not just a part of it using ajax. Please give a small example script for understanding if this is possible. Here i am trying to display only one url to user while i change from one page to another when he clicks on any of the links in the page.
You can of course request for a new page and load it via body.innerHTML = ajax.responseText;
I would strongly recommend against this though for reasons outlined in this post: Why not just using ajax for Page Requests to load the page content?
The whole premise really is that with
AJAX you don't need to reload the
whole page to update a small
percentage of that webpage. This saves
bandwidth and is usually much quicker
than reloading the whole page.
But if you are using AJAX to load the
whole page this is in fact
counterproductive. You have to write
customised routines to deal with the
callback of the AJAX data. Its a whole
lot of extra work for little to no
increase in performance.
General rule for where to use AJAX: If
your updating >50% of your page, just
reload, else use AJAX.
You will not only need to request for the new page, but then also take care of ensuring the old styles on the current page are removed and don't interfere with the new page. Theres all sorts of problems associated with what your trying to do. It's possible, but I recommend not to do it.
edit: actually you might be able to just do document.write(ajax.responseText) which should take care of overwriting everything in the document, including css styles etc. Though still don't recommend it.
When you're finished with processing the AJAX request simply use this JS line:
window.location.replace('<URL of the new page>');
This has exactly the effect of loading the new page via
....
When you make an AJAX request, a request goes off and brings you the contents of the URL that you have requested. Now technically you can do whatever you like with the contents (which could be HTML), you can replace any element within the DOM with it. Be careful however of replacing EVERYTHING on the page, you are more likely just going to want to replace what is within the tags.
If what you want to do is show one URL for multiple pages, AJAX is overkill. Why not just use an IFRAME?
This could be useful if your page was unsure if it was expecting back errors to be inserted onto the page or a "new" submission confirmation page. This can be used when you want to put a validation servlet (or whatever) in front of the submission servlet (or whatever). If the page always hits the validation servlet, you hide the submission servlet which actually performs the data update. In the case where the validation passes, forward to the submission servlet. The user never knows what happened in the background.
When the page gets a response back you could just look at the first portion of the response text and determine if it had a keyword set by the server, which means this is a new page. Remove the keyword from the text, and do document.write(ajax.responseText); as described previously. Otherwise insert the response text into your errorBox div and let the user retry submission.
