I have built an Admin section where i can see all the contents from database in a table. everything is fine but if the database table has thousands of rows I have to scroll down very deep. is there any way I can make links like `1,2,3.Next the way google search results do? or is there any even better way?
Isn't is going to be something like:
if($(document).height>2000){
//what should i do?
}
Looks like you are using jquery. If you are going to implement everything on your own it may be time consuming - although it would be fun!
To save some time, there are quite a few plugins available to achieve this. Refer:
https://datatables.net/
http://www.jqueryscript.net/table/Client-side-HTML-Table-Pagination-Plugin-with-jQuery-Paging.html
Since you may have huge data you should be using server side pagination instead of client side. Here is another SO link which explains the difference between them : Pagination: Server Side or Client Side?

I have created a simple project with two HTML page 'home' and 'details'. I have a spreadsheet of some data I want to show as list in 'home' page and on clicking shows associated details. I tried searching in internet but I was left with even more question than before. The data consist of 10 column and 1000 rows and might reach 5000 rows.
If you are facing trouble while learning DataBase, there is an alternative you can try and it is very easy to understand and implement in your code.
You can learn about JSON (JavaScript Object Notation), Simply you have to create a JSON file in which you can store the detail of all those 1000-5000 rows and render them on your Web page using JavaScript

Since a year and a half I am trying to figure out how some websites update their content in real time without AJAX method.
Please see this example website: https://pro.btcturk.com/en/basic/exchange/BTC_TRY
That website is changing many texts within content in different timing.
It means that when the server is updated with new values in the database then the website is listening to database changes and then reflecting/delivering inside content without ajax calls.
Can someone give an example how to achieve such functionality possibly using Javascript or PHP normal hand-code appreciated?
Thank you

Yes, I want something like Facebook post. But i'm unable to find any good resources for Java.
I'm making my project using Servlets and Jsp technologies. It has lots of contents in Database. I'm fetching it using Select *.. But i want to put something like Facebook for Loading more contents when scroll to bottom.
Problem is that i don't know anything about Ajax, So please how to implement it on my servlets project during fetching the data, At least give me an ideas.
HELP WOULD BE APPRECIATED!!
Regardless of technology/language, your process goes something like:
1) Request x records from service and display
2) When user reaches end of x records, fetch x more records from web service with offset = x
3) Display those records
Repeat.

I have created a webpage that takes a skill survey of students of a particular college but they are not ready to give me server yet they would want to see the prototype first how to show them the prototype without using the server but just using the web page that I have created?
A prototype shows how it works without actually working. So instead of getting real data, it can show fake data.
Your survey can show just two or three questions, and these questions can be hard-coded or loaded from a mock object, instead of loaded from the server. Also, instead of actually saving anything, it can just jump to the next question and show a text saying 'Thanks' when you are done.
That way, you can see if your survey has the right look and feel, and they can see that too. Also, it may make it a bit more clear to the server-builders what kind of implementation they need to make. A visible, 'clickable' prototype makes it easier to discuss details in the implementation.

Is there any possibility to save a DIV, that has contenteditable="true", to a MySQL Table? I need to use PHP for this (and JS as a "helper").
I though of doing something like this:
Putting a button on the site that copies the content of the contentEditableDIV to a formDIV (a DIV that is in a form with method="POST" action="send_to_mysql.php").
The button is supposed to auto-trigger the submit button/function at the same time.
But is there any other, more convenient way? I am quite a beginner in MySQL, so I couln't think of any other way yet.
I appreciate any kind of help or response.
With best regards,
Dave
Conceptually...
//contenteditable element
//read element with JS
//URIencode to PHP via JS/AJAX
//Send to database with PHP/PDO
You're in for a real can of worms if you want this to work well. Especially if you want this to work well AND be able to accept pasted content from MS Word.
