Running a Web agent without changing URLs. (IE only)

Here is a real timesaver and improved usability for the user - only one server hit and no time lost.

How many times do we have to run a Web agent to update information on other documents - while not wanting to move from this URL? We have to save this document - call the agent and then have the agent put us back here - 2 server hits and delayed time for the user. Potential cache nightmare if trying to use history.go(-x).

Here is a real timesaver and improved usability for the user - only one server hit and no time lost.

This can also be a good trigger to run agents in other databases especially when your LotusScript cannot access other servers. Pass any/all relevant information in the Query_String_Decoded you can run any agent anywhere you like - whenever you like.

Create a link on your document to call a javascript function The function then uses innerHTML to create an invisible IFRAME. (The IFRAME has height=0 width=0 so occupies no space on the form.) The src of the IFRAME is such that an agent is called and runs right there - without changing the URL of the existing page.

on the form passthru HTML - <DIV id="divBookmark"></DIV>
call the OpenAgent function below

function OpenAgent(){
	//link is the would-be URL of your agent
	var link="http://servername/database.nsf/agentname?openagent"
	//create the IFRAME in the div as innerHTML
	var sTemp="<IFRAME src='"+link+"' width=0 height=0></IFRAME>
	document.all.divBookmark.innerHTML=sTemp
}

A working example could be a "Send Email" button which links to an agent to send the mail - without having to move from this page. You could pass the user's name etc in the Query_String_Decoded.

When the agent is complete you could have it print a return to notify the user
Print <SCRIPT>alert('Email Sent')</SCRIPT>
