Compare search results page

1.   Next to each results on my search page is a check box.
2.   If a user selects at least two boxes, then clicks a button at the bottom called "Compare".
3.   Clicking on the "Compare" button should take them to a split page that has details of both selected records.

I see this feature often on the web. Just not sure how it can be accomplished in coldfusion. Any suggestions?

yes you can.
1) you can pass the parameters in the form and bring to next page
2) the page has loop over table column ...
i) loop over the number of the variables passed..if two checkbox then two column
ii) then loop over query and bring their info back from database
iii) display them together

this will be big loop with
column, query, display ...
this way you can do as many as you want...

use this function

<cfscript>
function fnModified( unmodified, modified )
{
      var stringReturn = '';
      unmodified = trim(arguments.unmodified);
      modified = trim(arguments.modified);
      if ( compareNoCase(unmodified, modified) EQ 0 )
      {
            stringReturn = unmodified;
      }
      else
      {
            stringReturn =  "[original] ";
            if ( arguments.unmodified IS "" )
            {
                  stringReturn = stringReturn & "(NULL)";
            }
            else
            {
                  stringReturn = stringReturn & "<span style='color: gray; font-weight: normal;'>#arguments.unmodified#</span>";
            }
            stringReturn = stringReturn & "<br>[edited] <span style='color: red;'>" & arguments.modified & "</span> ";
      }
      return stringReturn;
}
</cfscript>

it works like this

#fnModified( "test1", "test2" )#
