Beware infinite refresh if not in a function!

Re: force to refresh browser
Thanks!
well, window.location .reload(true) does whenever control is hit that line,
it does refresh.
What I want to do is server side trigger send message to client browser to
refresh it.

Technically, you can't in a normal cross-browser internet environment
(that is, activeX, applets, and COM notwithstanding ).
If the page should be refreshed every so often, put it in a setTimeout.
This is common.
If the user updates the DB via a popup with the main window on a
particular page you want to refresh, write a script as output to the
popup that calls window.opener.l ocation.reload( true).
Other situation, please elaborate. We can probably find something that
works for you.

Re: force to refresh browser
Thank you for your help.
I'm displaying hotel information from DB.
What I want to is
First, I will get the hotel list and display with no rate. ( since getting
rate takes time)
Whenever rate information is ready to update. refresh user's browser.
but how?
Thanks.

If you are getting the hotel list from the DB, getting the rate should
take an inconsequential amount of time, especially if the DB is set up
properly and a concise SQL statement is used. Views can be helpful for
this if the rate is a calculated field or is keyed by a number rather
than a hotel name.
Rates do not change often enough to need to refresh the user's browser
more than with a setTimeout for some amount of time.
Perhaps what you really need is help with your SQL query.
If you're not getting the hotel list from the DB, why not? That is much
easier than manually changing pages. :)
The DB must have the hotels in there or it would be impossible to look
up rates.
How I would do this: query the DB for the list of hotels and rates and
write the whole thing dynamically at once. I do much more complicated
things with billing data for one of my pages and it takes less than 10
seconds to run and load.

Re: force to refresh browser
Thanks.
I did not explained in detail so I can avoid some confusions.
But I guess it did more harm than good.
Hotel list are coming from our DB and rate are coming from GDS in XML.
I have a java object created with list first and displays and trying to
update as soon as I got XML response.
XML response is quite slow. ( you know there is nothing I can do).
I can wait XML and display all together. but I'm just seeking a way to
display list of hotel first with some animation indicating
rate is being updated and display rate when it's available.
is that make sense now?

Yes, much.
Okay, there really isn't a good way that I know of (cross-browser) to do
this. If you're using IE only (intranet application) let me know,
because you have more options. Generally speaking, once the page is
written, the server knows nothing else about it. It can't refresh the
browser, because the connection is over. COM and ActiveX are exceptions,
but are IE only (AFAIK).
Anyway, the way I would handle this is with an "invisible" iframe
(styled to hidden or 1px by 1px the same background color as the main
page). I would have the iframe wait for the XML, then when it is
received, update the encompassing page. This doesn't require a refresh,
just DHTML.
That still requires NN6+/IE5+ and other browsers that support
iframes/DHTML, but it's better than IE only. Last I checked at my site,
95% of my viewers had browsers that were IE5+ or compatible (opera can
spoof this so be careful).
Do your target users have updated browsers? Do they have permissions to
update their browsers if they need to (i.e. people at schools and
libraries do not.)?
I'm sure there are other ways to handle this, such as applets, COM,
ActiveX, etc, but all require knowing quite a bit about your users'
browsers. For example, using an applet is a bad idea if your users
access the site from public facilities, since they don't have permission
to install an updated JVM should they need to.

The pages I gave you show that. test2 updates test1. I used a form for
ease and quickness, but you could do any block-level element.
What you do is have the query / xml run in what was my test2.htm. When
it loads, the xml is done. When it loads, have the script write to what
was my test1.htm.

Re: force to refresh browser
then Until test2 is fully updated user is not seeing test1?
Well, my task is while user watching test1.
updates test2 and when update test2 is done refresh test1.
so user can see updated info.
is user has to wait test2 is updated and while doing updating, user don't
see any info.
It is kinda same as before.
