当布尔值设置为true时，如何获取一个HTML / ASP行的背景颜色？

Question

I've got a table generate on page-load that is full of data. When the user clicks an ID, that row needs to highlight. Right now, I've got it so that when the user clicks the ID, a boolean is set true, and then some other stuff happens. I have it set so that when the boolean is true, that row will be highlighted. However, this isn't happening. Can you help me figure out why?

<%  
    If RS.RecordCount > 0 then 
        Do While Not RS.EOF
            if RS("ROLL_ID") = IntRollID then
                boolDetailTable = true
            end if
%>              
<TR <% if boolDetailTable = true then %> bgcolor "#CCFF00" <%end if%>>
    <a target=_top href="<% = getInfo(RS("ROLL_ID"))%>" onMouseOver="window.status='Click to get info';return true;" onMouseOut="window.status='';return true;">
    <TD style="width: 9%; cursor: hand; border-right: none; align: center; vertical-align: center;" 
        title="Click to get info">
        <font color="navy"><%= RS("ROLL_ID")%></font>
    </TH>
    </a>
    <TD style="width=25%"  style="font-size: 12pt" align="center">&nbsp; <% = RS("ROLL_FINISH_DESC") %></TD>
    <TD style="width=20%" style="font-size: 12pt" align="center">&nbsp; <% = RS("ROLL_DIAMETER") %></TD>
    <TD style="width=20%" style="font-size: 12pt" align="center">&nbsp; <% = RS("ROLL_CROWN") %></TD>
    <TD style="width=10%" style="font-size: 12pt" align="center">&nbsp; <% = RS("ROLL_LOCKOUT_YN") %></TD>
</TR>
<%

        RS.MoveNext()
        Loop        
    end if
%>

Answer 1

如果你有一个，请尝试.css

tr.active{color:#CCFF00;}

Answer 2

For starters you need to change one of your tags in the code below - you need to start with either the <th> or end with the </td> as you have a mismatch.

For this example I changed </TH> to </TD>

You will also notice I added an onClick(this.parent); to the <td>

<TD onClick="SetColor(this.parent);" style="width: 9%; cursor: hand; border-right: none; align: center; vertical-align: center;" 
    title="Click to get info">
    <font color="navy"><%= RS("ROLL_ID")%></font>
</TD>

The OnClick will send the elements parent - in this case the row itself ( <tr> ) to a function called SetColor(elem)

Have a javascript function like this in your page:

function SetColor(elem){
      elem.style.backgroundColor = "#ff0000";
}

This should change the row to a red color for you.
