refresh page automaticlly

[lampoin]

Hi


I have a page with a table of 1000 rows. If the user is on a f.ex 500 record row,
how can I refresh the page automatically without pressing on a 'refresh button'? I want the page to appear on the same place (500 record) and not on the begining of the same page (I know that by using META tags the page wil be refreshed and appear on the begining of the same page) .



I am looking forward to your answer as soon as posible.


Thank you in advance

what does this mean?

If the user is on a f.ex 500 record row,

can you give a little more detail on when you want the page to refresh?

I have a large table of records shown on a web page, and the user is in a middle of this page.I need to refresh the page on a regular basis,f.ex. each 10s. There is no need for returning the user at the beginning of the page and scrolling through many records, but to return the user on the same place like previously.
So the user will not notice that the page is actually refreshed.

Do you have any idea about this problem?

i get it now. it's going to be really difficult. even if you managed to get it working ( with javascript probably ) it would still jump when the data refreshed.

if data is refreshing, then you are using a server-side language to generate the page right?

the best thing for you to do is set a limit to what the user is viewing. view maybe 50 rows at a time ( whatever fits in 1 page without scrolling ) , ... then make a paging .. but when the page refreshes itself, it will never move. this will make pages load faster too since you are only looping through 50 rows of data.

maybe there is a good way, .. but i don't know it.

Yep, sounds like a pain. Even loading 500 "rows" of whatever in a static html file is going to be noticable, so it'll be slower in something dynamic. (ignoring that a visible refresh every 10s [even if it did return the user to the spot they were reading] sounds horribly annoying.)

As far as returning them to their current spot, that's even harder. How do we know where they're scrolled to? eg: They PGDN'ed several times and now "see" rows 150-164 on the screen. (obviously variable by screen size) You're looking to return them to row 150 to continue viewing with the possibility that there's new data below?

I'll let you know if I think of something, but it seems very awkward. Now if there were some form fields and the cursor was in one, it might be a bit easier.

Its best to group them, like sde said. You know how online dictionaries are constructed, and you can have a navigation on top with links to each group. In my opinion, thats the most organized way, instead of displaying that much data on one page.
