CFLOOP In CFGRID

Question

I am populating the grid from a query that displays the
perosn's name, date of attachment and attachment name, etc etc. I
am offering the option to delete these attachments based on two
criteria.
1. The session.role is the administrator role.
2. The owner of the attachment (the person that put it up)
can delete the attachment.
The problem I am having is that more than one person can add
an attachment to the file. I want to be able to limit the items
they can delete to those that they put up. Is it possible to cfloop
through the grid so if the person is the owner I can give them the
check box, if they are not the owner it is inactive. Here is the
code I am working with:
<cfgrid name="attachmentList" query="attachmentsQuery"
height="220" rowheaders="false"
onchange="#launchAttachment#" selectmode="edit">
<!--- Delete Only If Session. Role is 10 Or session.admin
is Owner --->
<cfif session.role EQ 10>
<Cfset enable = "yes">
<cfelseif Session.admin IS
#trim(attachmentsQuery.AttachOwner)#>
<Cfset enable = "yes">
<Cfelse>
<Cfset enable = "no">
</cfif>
<cfgridcolumn name="checked" header="Delete"
type="boolean" width="46" display="#enable#"/>
<cfgridcolumn name="AttachOwner" display="no">
<cfgridcolumn name="AttachID" display="no">
<cfgridcolumn name="AttachName" header="Attachment"
select="no" />
<cfgridcolumn name="Name" header="Attached By"
select="no" />
<cfgridcolumn name="DateTimeKey" header="Attach Date"
mask="MM/DD/YYYY" select="no" />
<cfgridcolumn name="AttachmentType" header="Attach Type"
select="no" />
</cfgrid>

You you can use CFML inside of a JavaScript <script..> block to dynamically build the JavaScript code to send to the client.  It is a very powerful technique for building highly interactive web sites.
Just realize that all the JavaScript code is going to be completely built by the CFML and then sent to the browser client through the web server where the JavaScript is executed completely independent of anything that is running on the server.  The JavaScript can not read or write variables on the server or vice-a-versa.  But it is quite easy to export variable values from ColdFusion to JavaScript.  It is a bit more work to export variable values back requiring either the browser or JavaScript to make a new request of the server to send the data.  AJAX does allow this to happen behind the scenes making it look like the data is being shared.  But in reality it is being passed back and forth with independent HTTP requests and responses.
