i am creating a table with pagination using datatables. i have big data called using ajax. The ajax call returning 10 data at once. when first call, it takes first 10 data from ajax call. then when click next page it will take another 10 data. As i know, datatables collect all data and do it own pagination. How can i solve my problem. Example if ajax returning 100 data from backend, how will the datatables know 10 pages it need to generate. and the data will only call when we click next.
Thanks in advance.
You can either:
Retrieve 100 data records from your back end at once, calculate the number of pages needed in javascript and display 10 first records. When the next page button is clicked, your display the next 10 records, and so on.
Retrieve the first 10 data records from your back end along with the offset of the last record. Display your records to users. When the next page button is clicked, call another ajax to retrieve the next 10 data records (that should be easy since you got the offset of the last record), and display them again.
This is the general idea on how to solve your problem. Hope it helps!

I'm working on a Django project that runs a background task every time a form is submitted. It takes roughly 2sec to complete each task, when completed, the results are saved, ajax is supposed to perform page refresh but not the whole page, and what I have so far is:
$.ajax({
success: function(){
setInterval('location.reload()', 10000);
}
})
It works as intended, but it's wrong. I have rather limited experience with js. However, I'd like to refresh only the newly added row(s) in the table. I came across jquery .load() but I've been staring for a while now, please any help?
EDIT:
So js/ajax is just responsible for page refresh on a specific row like so
id
name
date
log
status
1.
task1
today
pending...
pending...
Each row has a corresponding table in the database, on task completion log and status are no longer pending but updated with DB objects.
Django handles form validation and submission on another page which gets redirected to this one with the tabular result, the user waits for a few sec and boom, ajax drops the magic.
I am using igx-grid. I am retrieving all data in one call, suppose I am on 3rd page, while filtering data it searching the data from the whole data, and it goes to "Page 1" automatically, I need a way to filter data in current page only and don't paginate to Page 1, it should be on current page only. Is there any way to do the same? Thanks in advance!!!
Edit: I am facing same issue in Server Side Pagination also.
Filtering performed on the data in any column of the igx-grid is not an operation which works only on the specific page data, but on the entire data set. If you need only data within the current page to be filtered, then the data within the current page will be less than the page size and the data state in general in the grid will go out of sync.
In order to get the current filtered data on the current page with server-side paging, you can extract the filteringExpressions from the grid and send them in the request for paging to your backend service. Then first filter the data and subsequently page it and return only the page size back. In pseudo code this will look something like:
data.Where(d => d.something meets condition).Skip(page).Take(pageSize)
The result would be something like this:
https://stackblitz.com/edit/github-w6x6a7?file=src/app/grid/grid-remote-paging-defaultTemplate-sample/remote-paging-default-template.component.html
Now the grid does reset the pages when client-side filtering is performed, because when filtering the data, the number of pages is reduced and the current page that the user is on may no longer exist.
Examples on the server-side paging and filtering in the igx-grid can be found here:

I have a database with a table having a big number of rows. I am fetching the data in this table and displaying it in an HTML table on a web page.
My requirement is to display 20 records initially and then when the user clicks a button labelled Next, I show the next 20 records and so on...
So I have initially fetched first 20 rows from the table in my PHP (server-side), and then assigned a JS function to the onclick attribute of the button labelled Next. Inside this JS function, I use an AJAX call which brings me the next 20 rows. Then within this JS function, I replace the HTML rows with these new rows.
I need something like this:
The question is that are there any plugins available which can implement that functionality for me? If a plugin is available, implementing it manually wouldn't make sense because being a rookie, I can't develop it better than the developers of that plugin.
Yes
This is called pagination - a quick search for "ajax pagination mysql php" or similar brings up a wide range of options. I can't recommend any particular one as your question is too broad; I can only reasonably go as far as a definition.
Internally they use the MySQL LIMIT keyword which may help give further things to search for or experiment with depending on your actual use case.
I am new to DataTable.js jquery plugin and trying to put my best effort to explain the stuff I want to know.
As of my requirement, I have to fetch only 10 records by default at a time when I do an ajax request even it match 100 records with the search criteria.
But the no. of records will change based on the user selection. ie. it may be 5 or 10 or 25 and so on which is available in the show records per page dropdown control.
Ex.
Consider I have 50 records that matches my search criteria and I selected 10 records to show per page. So the first ajax request provide only 10 records and it will be displayed in the table. At the same time I have to show the pagination as 1 2 3 4 5 buttons.
I want to know how to set the pagination like above using total no. of records and no. records shown per page?
Is there any way to do this?
Any help will appreciate!.
Data table basically works on html table and create pagination on table data. Datatable does not provide this type of functionality. may be following link help you
Ajax request for server side data for each page in Datatables
So I currently have a set of data that is about 5000 records. I have been using the tablesorter plugin and it has worked great for my smaller tables.
however the way I have it set up currently on the page with the large amount of records is that it retrieves all the records from the database and populates the data into the browser and then the tablesorter plugin with break it into pages of 100 records.
my issue is that the I need to get it working in a way where it will load up the first 100 records and have it so it doesn't load the next 100 records until I hit the next page button. But I still have to be able to sort through all 5000 records if I sort by any of the headers.
I am some what new to working with this so I am not sure how I could go about doing that.
so to summarise
I have 5000 records
I want to have 100 of those records display when the page loads
if I sort by any of the headers it needs to sort through all 5000 records
if I hit the next page button it needs to load up the next 100 records in line.
You should give datatables a try then.
Tablesorter has a pager plugin that can handle server side paging requests. Here's a link to the example:
http://mottie.github.io/tablesorter/docs/example-pager-filtered.html
You can run ajax requests that will handle that pagination, as well as sorting and filtering. However, you'll have to build the calls to the server. The process is pretty well documented in the documentation on Mottie's Tablesorter fork. I recently used Tablesorter to handle a table with 50,000 rows.
