Getting java to recognize radio buttons checked

[Pattycake245]

I am trying to get java to see that a radio button is checked but it doesn't "see" it. It is a Cold Fusion app and there are a set of three buttons all with the same name but different values. When a radio button is selected and the form is submitted it is supposed to load the same page again, but with the radio button that was checked to still be checked and the other two buttons disabled. But what it is doing is disabling all of them because it is not recognizing that I have checked one of the buttons. Does this make any sense?

In it's simplest form, this is what my form looks like:

function doRadioCheck()
{
for(x=0;x<frm_monitor.elements.length;x++){
if(frm_monitor.elements[x].name.indexOf("rsch_sel") != -1){
if (frm_monitor.elements[x].value!="" && frm_monitor.elements[x].checked==true)
{
<cfset request.chk="CHECKED">
<cfset request.edit="">
}
else
{
<cfset request.chk="">
<cfset request.edit="DISABLED">
}}}
</cfif>
}


<form name="frm_monitor" action="mon_entry.cfm" method="post">
<table border align="center">
<tr>
<td Valign="left"><input type="radio" name="rsch_sel" value="VG" doRadioCheck() #request.chk# #request.edit#>#disp_vg#</td>
<td Valign="left"><input type="radio" name="rsch_sel" value="G" doRadioCheck() #request.chk# #request.edit#>#disp_g#</td>
<td Valign="left"><input type="radio" name="rsch_sel" value="NI" doRadioCheck() #request.chk# #request.edit#>#disp_ni#</td>
</tr>
</table>

<cfoutput><input type="submit" onClick="return doFormSubmit(this.form)">

<cfoutput>
</form>

Is this even possible or am I barking up the wrong tree here?

thanks, Tim

It is possible but it seems your function only looks at teh radio buttons that are already checked

 if (frm_monitor.elements[x].value!="" && [b][COLOR=blue]frm_monitor.elements[x].checked==true[/color][/b])

shouldn't you check all of them?

Oh, look at that, good point! Didn't even notice that. Yes you are right I do need to check each one and if it is checked, check it, else disable it. What would the syntax be then?

I don't do coldFusion but here is what it would look like in ASP (no javascript used at all - all logic is server-side)

<tr>
<%
  select case request("rsch_sel")
    case "VG"
      response.write "<td><input type=radio name='rsch_sel' value='VG' CHECKED></td>"&_
        "<td><input type=radio name='rsch_sel' value='G'></td>"&_
        "<td><input type=radio name='rsch_sel' value='NI' ></td>"
    case "G"
      response.write "<td><input type=radio name='rsch_sel' value='VG'></td>"&_
        "<td><input type=radio name='rsch_sel' value='G' CHECKED></td>"&_
        "<td><input type=radio name='rsch_sel' value='NI' ></td>"
    case "NI"
      response.write "<td><input type=radio name='rsch_sel' value='VG'></td>"&_
        "<td><input type=radio name='rsch_sel' value='G'></td>"&_
        "<td><input type=radio name='rsch_sel' value='NI' CHECKED></td>"
    case else
      response.write "<td><input type=radio name='rsch_sel' value='VG'></td>"&_
        "<td><input type=radio name='rsch_sel' value='G'></td>"&_
        "<td><input type=radio name='rsch_sel' value='NI'></td>"
  end select
%>
</tr>

Pattycake-

I'm a little confused. This looks like JavaScript with nested CFML, which is quite interesting to me.

Are you sure this is what you want, and not straight JavaScript?

mwolf-

I'm not sure if you had the chance to see before those posts got correctly deleted, but I want to thank you again for your kind words and recognition. It was much appreciated.

cLFLaVA - I didn't read flag them because I thought that the user was just confused - but I was VERY close to red flagging the ungrateful response that you received. It is not unusual to have a cross-forum posts between ASP or ColdFusion and JavaScript since both are often used together. Should this post be in the ColdFusion forum? Probably, since users there are more likely to have been exposed to this kind of thing. The posts to which you are referring were purely ASP and really were in the wrong forum altogether(as you pointed out).

I had red flagged them as well. As for this post, it seems it's in the correct forum, I'm just not sure what the asker is asking. There is CFML nested inside of JS, and I'm not familiar with CFML, so am trying to get clarification.

p.s. i had red-flagged them as well - there's no need to a) lash out in that manner and b) post the same question 3 times in a matter of 30 minutes.

thanks again.

cLFLaVA -

I have nested ASP in JavaScript before
var msg = "<%=request("message")%>";
or some such thing.

But from what I remember of ColdFusion, it more intuitive and can be embedded more. I think that my solution would work fine in ASP but it may be cumbersome for a ColdFusion programmer - I'm not sure.

You know what guys, I think I will do it the way mwolf00 showed. I kind of had something like that before but I wanted to try it with javascript. I thought I could use Cold Fusion variables inside the javascript code and attach those to all input fields but it is more pain to do it this way, and possibly slower than just using case statements in CF.

Thanks for the help. Those red-flagged posts aren't something I did are they?

No, another thread earlier today...
