It never ceases to amaze me that many developers strive for code reuse
and modularization and separating business logic from presentational
code but rarely seem to apply the same principles to their HTML coding ;-)
Regardless of the CF syntax used (iff / <cfif>), here's a more efficient
way to code this functionality:
The following CSS code should be put in an external style sheet:
..evenRow {
background-color: #ccc;
}
..oddRow {
background-color: #fff;
}
Then in the cfm template:
<cfset rowClass = "oddRow">
<table>
<cfoutput query="someQuery">
<cfif someQuery.CurrentRow mod 2>
<cfset rowClass = "oddRow">
<cfelse>
<cfset rowClass = "evenRow">
</cfif>
<tr class="#rowClass#">
<td>#someQuery.CurrentRow#</td>
<td>some data</td>
</tr>
</cfoutput>
</table>
This way the actual colors used are not hardwired in the template and
can be changed from the CSS file and the HTML markup is separate from
the presentation.
Cheers!
