Hello all;
Here's an interesting idea / question:
1) With CSS2 in both NS6 and IE 5.0 + , it's easy to manipulate HTML in a particualr object directly and to change it on the fly without hitting the server and without refreshing the page. If you aren't familiar with that, you can do it by sticking whatever HTML block you want to manipulate inside a DIV that has an ID, like this:
<DIV id="dynamicblock">
I'm some stuff you want to replace on the fly
</DIV>
Then, if you happen to have some javascript variable in which you have plugged something new, you can
document.getElementById("dynamicblock"
.innerHTML=yourvariable;
And poof!
OK, now the thing that is neat about that is that you can make major page alterations without refreshing the page.
What I would LOVE to do is to set the content of an identified object (as seen above) by poking something into it directly returned from the server. Something like this:
document.getElementById("dynamicblock".innerHTML =
Has anyone figured out a way to do something like this?
The problem is that I don't want to refresh the page the user is viewing every time I ask the server for some data. I have a CGI that peeks at a database delta table ( a change table). This table tells me what of some values have changed since the last time I happened to look at it. I use it to alter the display on the client side based on a changing state an the server. The CGI returns what has changed, and the client manipulates the display via javascript to reflect the changes. NOW, One way to make all this invisible to the user is to return that information into a tiny frame that the user can't really see (as an array, for example) and to manipulate the view frame based on that data. But that's a cumbersome approach. It would be much much nicer if I could directly target an object ID with the results of the server query.
Anyone know of a way to do that?
Thanks
