is there an error here ?

[Guest]

Please check the string in "stralertscript ".

if ( ds.Tables["studentTestpaper"].Rows.Count == 0 )
{
stralertscript = "<script language='javascript'> "+
" function alert() "+
" { "+
" alert ('Testpaper not found'); "+
" return true; "+
" } </script> ";

Page.RegisterStartupScript ("stralertscript", stralertscript);
}

What I wanted to do was to pop up an alert message. The IF function works
fine, but the alert doesn't appear. Should I use RegisterStartupScript or
RegisterClientScriptBlock ?

TIA
Andrew.

My guess is that your problem is the name of your function. You have a
function named "alert" which is a javascript built-in function. It's no
different than if you tried to name your function "if" or "true" Simply
renaming the function to something else. Use RegisterClientScriptBlock.

In addition to incorrectly using "alert" as your function name, you say
"What I wanted to do was to pop up an alert message".
So I understand that when the page loads on the client side you want the
message to pop up? Then something must call the function as well. If so,
then changing your "stralertscript =" to the following will give the pop up,
and use RegisterClientScriptBlock

stralertscript = "<script language='javascript'> "+
" alert ('Testpaper not found'); "+
"</script> ";

Hi,

Thanks for your reply. I tried changing that alert word to stralert, but it
still doesn't work, i simply do not see any alert msges pop-ing up on my
screen, lolz....

I found out that I could use this line to solve my problem:
Response.Write("<script language='javascript'> alert('Testpaper not found');
</script>");

This works. I do see an alert message pop-up.
Still dun know why my previous code does not work. The debugger just goes
pass those lines.

cheers,
Andrew.
