HTML Parameters? 1

[grega]

On some links, I see from the status bar that they take the form;

http://www.weblink.com/somepage.html?setting=true

Is this some method of supplying parameters to an HTML page .. if so how (briefly) is this done? I just need something to get me started

Greg.

grega,

> Is this some method of supplying parameters to an HTML page

Yes

url?paramName=paramValue

The '?' begins the 'Query String'. The string consists of ( name=value) pairs. The string must be UrlEncoded.

and to add some more parameters, separate them with &

url?param1=value1&param2=value2&...

Thanks folks ... and how do I use them in the page?

Greg.

the easiest way to use them in a page is to use asp..

asp has a querystring object that makes it easy to retrieve the vale for a key.

like:
url is

http://www.blah.com/defualt.asp?recipient=adam@aauser.com

<%
email = Request.QueryString(&quot;recipient&quot;
%>

without using asp, its a little more difficult, but you can probably parse the location.href with client side javascript.

Actually the query string is provided in the 'window.location.search' property. It can be parsed using javascript String.split() method.

Hope this helps

Often this is done as a marketing tactic. The query string doesn't actually mean anything to the page it is used on. However, it may indicate where the visitor is coming from (email campaign, banner campaign, etc.). So, in the usage statistics, it will show that page as unique from the same page with a different query string. This way you can track the effectiveness of your advertising without creating seperate pages for each campaign.
