Having read Imar Spaanjaars excellent note on "sharing a server-side variable with client-side" I can see a solution to this problem but I wonder if there is a more 'direct' approach.

I need to use an interval timer to change a short text quotation. These quotations come from a mySQL database table. I have set up an interval timer with javascript and a sql call to extract the random quotation. I need to connect the two. I had hoped to call the asp routine from client side Javascript but unless I have missed something, that needs Remote Scripting but the server I am using does not seem to support RS.

I see that I can read the set of strings (not too many at present) into a session or application array at run time and choose one of those at random at intervals.

But is there some way of triggering some asp code from an interval timer and passing the result of that call back to the client side javascript thus bypassing the need to hold the quotations in a session array?

any help would be appreciated.

Regards

Nick

You have two basic choices, either load all the quotes on first access onto the client and then select one at random entirely client side, you never need return to the server. Alternatively have something like an iframe or frame whose content is refereshed periodically, each time a different quote is displayed.
You don't need remote scripting.

The quotes are only one liners - so I propose to change the content of a <span> element once I get a fix (as per your other post)and pull out a random quote on the client side as you suggest. I had intended to load the quotes into an application array but I see that application level arrays aren't allowed.

Hii Nick,Joe
I have another approach to your question.

<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">
function NextQuotation() {

var obj = new ActiveXObject( "Microsoft.XMLHTTP" );
var url = "http://myurl/GetQuotation.asp"
obj.open( "POST",url, false );
 obj.send();
 nextquotation=obj.responseText
 alert(nextquotation);
}
</SCRIPT>
<form name="test">
<input type="text" name="quotation_id" >
<input type=button name="getQuote" onclick="NextQuotation()">
</form>


And my "GetQuotation.asp" ASP page is like
<% response.write "hii" %>

Since You want to get quotation from the database (MySQL) u can pass the quotation id to the url i.e (GetQuotation.asp page) and get then next quotation and display the quotation randomly .
Hope ,It will help to find the solution.

Cheers :)

Thank you Vinod. I will have a closer look at that. Does using an ActiveXObject present problems with non IE browsers? I need to do a bit of work to understand that side better.

I do have Joe's suggestion working OK now but all ideas help.

Thanks - Nick

ActiveX controls only work with IE.

Where will you be in 100 years?
Try new FreshView 0.2!

That is what I wondered and I can't be sure that is all my clients will use.
Thanks
