Subject RE: Appending html:option to a html:link
Date Thu, 01 Jul 2004 13:58:05 GMT
Shove any parameters from your map in to the queryString using jstl

<c:forEach items="${mapOfParams}" var="bleh"><c:set var="blehString" value="${blehString}&${bleh}"/></c:forEach>

  var queryString = "?<c:out value="${blehString}" />";

would give you :

  var queryString = "?foo=bar&cheese=yummy";

(thats assuming each value in mapOfParams was a url param in the form "name=value" otherwise
you would get queryString = "?foo&cheese"; if you see what I mean)

Thank you for your reply.

The only thing that is missing from this are the map of attributes that
I was originally appending to the html:link.  Is it a case of - you can
have one or the other?

Cheers,

Chris
