Dinamic string read from database

coldspirit

Here it goes:
Is there a way to make this string being read in real-time(pseudo real-time).
Say it will display 6000 symbols and once, and then there will be 4 scroll buttons(2 up and 2 down/ by lines and by lot of lines at once)

*Also add there a button to find your book-mark. It will most likely produce a lot of stress on the server and database, since I will have to duplicate books for each reader to have their own marks. Maybe it can be done with just some ordinary code without actually messing with database.

However without making marking function available, the code should be easy.
But I don't really know how to do it.

The point I need a web-link to not reload the page - only reread the information from text field and scroll it.

The Idea is to make it look like scrollable web-book reader.

Can you advise me how to do it or where to start?

if i'm understand your question right jquery may help you to make such a scroll:
Check the jQuery.ScrollTo plugin, you can scroll to determined positions (fixed or absolute), using selectors, DOM elements, and more...

look to the demos...

You can have an unlimited length area where you catch bookmark events. You can save the coordinates.

Maybe this helped.

Well JS is client side, and well it's not php, I'll try it anyway.
Also it seems that the string (table, data, whatever) inside <div> is loaded all at once.
What I need is: load info every time I click on scrollDown button. The upper line is erased and can't be read again without clicking scrollUP, while the lower line appears and can be read.
The amount of information accessible to a reader is limited to a certain amount of lines at a time.

The idea was to make it with php.
The thought was to make a function that will send itself to a server and then server must send back the portion of html-code to a certain part of a page(refreshing data inside <div> only). I'm not sure if it's possible with php =), is there a function that will produce portion of page reload?

you are asking a client side question, php has no idea about scrolling\buttons theses are client side issues.

Ajax is what you need to update the text with out reloading the page.
