Java-script and vb.net

[Bart Schelkens]

Hi,

how can I execute a piece of Java-script after a piece of vb-net-code has
been executed?

Thx

javascript should (probably, I don't exactly know what you want to do) execute
on the client-side, and vb.net on the server side. There is NO way to mix execution
on these two platforms. (unless you are prepared to solve some complicated
communication issues)

You CAN use RegisterStartup Script or RegisterClientS cript to generate (java)script
from server side code, which can get executed when it finally arrives on the client.

Hans,

the problem i'm trying to solve is this:

My website consists of 2 frames.
I have a button in Frame1 that checks some things on my database.
According to the result of those checks, I need to refresh my Frame2.
I got some java-script to refresh my screen but I can't get it executed at
the correct time.
And apparently there's no VB.Net code to get the same result.

Just use RegisterStartup Script() or even a Literal WebControl to insert your
javascript to refresh frame2.

When your server-side code finished, the browser will reload and case the
scripts to be excuted.

Actually, I think when the page reloads, your frame2 should be refreshed
automatically. If it does not
seems to refresh, try disable the cache and set expire at "page" tag first.

I've put this code in a function that I call to register the script :
js = "<script language=JavaSc ript>"

js &= "function RefreshMainFram e(item){" & vbCrLf

js &= "window.open('h omepage.aspx',' mainFrame');" & vbCrLf

js &= "}"

js &= "</script>"

RegisterStartup Script("Refresh MainFrame", js)

The script is registered fine, but it doesn't execute.

What did I do wrong?

RegisterStartup Script("Refresh MainFrame", js)

The script is registered fine, but it doesn't execute.

What did I do wrong?

You specified a function, but didn't call it anywhere.
Add a "RefreshMainFra me(..)" call after the function
definition (by the way, that "item" argument isn't used
in your code?)

"StartupScr ipt" is rendered at the end of the page,
so everything important should already exist before
any script tries to access it, but you still have to *call*
functions.
"ClientScri pt" is rendered at the start of the page,
so that functions defined in that block are available
when they are referenced later.

A note: the first parameter of RegisterStartup Script
doesn't specify "a function to be called", but is just
a server-side identification string. If you can generate
this script from multiple places (it's in a control, and you
might use multiple copies of that control), then you
can use this identification to find out if it's already generated.

You mean that i should write it like this :

js = "<script language=JavaSc ript>"

js &= "function RefreshMainFram e(){" & vbCrLf

js &= "window.open('h omepage.aspx',' mainFrame');" & vbCrLf

js &= "}" & vbcrlf

js &= "RefreshMainFra me()" & vbcrlf

js &= "</script>"
