Coldfusion: Block certain fields based on input field

I have a form with 7 fields (fields 1 thru 7). If field1=A, fields 2, 3 and 4 should be blocked and fields 5, 6 and 7 can be entered. If field1=B, the other side around, fields 2, 3 and 4 can be entered and fields 5,6 and 7 blocked.

How can I accomplish this in coldfusion?

Thanks.

Coldfusion is a server side technology therefore it cant make changes dynamically on the client side.

However you can use javascript ( theres also cfscript which is similar to javascript ) ::

<script>
function chkMyField(){
      if (document.form1.radio1[0].checked==true){
            document.form1.txt2.disabled=true;
            document.form1.txt3disabled=true;
            document.form1.txt4disabled=true;
            document.form1.txt5.disabled=false;
            document.form1.txt6.disabled=false;
            document.form1.txt7.disabled=false;
            document.form1.txt5.focus();
      } else if (document.form1.radio1[1].checked==true){
            document.form1.txt2.disabled=false;
            document.form1.txt3.disabled=false;
            document.form1.txt4.disabled=false;
            document.form1.txt5.disabled=true;
            document.form1.txt6.disabled=true;
            document.form1.txt7.disabled=true;
            document.form1.txt2.focus();
      } else {
            document.form1.txt2.disabled=true;
            document.form1.txt3.disabled=true;
            document.form1.txt4.disabled=true;
            document.form1.txt5.disabled=true;
            document.form1.txt6.disabled=true;
            document.form1.txt7.disabled=true;
      }
}
</script>

<body onLoad="chkMyField();">

<form name="form1">
<input type="radio" name="radio1" value="A" onChange="chkMyField();"/>
<input type="radio" name="radio1" value="B" onChange="chkMyField();"/><br />


<input name="txt2" size="10" value="" /><br />
<input name="txt3" size="10" value="" /><br />
<input name="txt4" size="10" value="" /><br />
<input name="txt5" size="10" value="" /><br />
<input name="txt6" size="10" value="" /><br />
<input name="txt7" size="10" value="" /><br />
</form>

</body>

Also remember validate on server side as java script can be easily disabled and you can't do anything about it. In case something is invalid, return to the page with an error message.

I tried your code and it worked fine with the radio button but actually I have a drop down list with 5 values.
If the field is value1 then it should do part 1, else it should do part 2. I don't know scripting very well. How do I do I change the if line ( if (document.form1.radio1[0].checked==true)) to handle a drop down field?

Thanks. Errol

say you have
<select name="select1">......</select>

Then you change the code posted by stu215 in
if (document.form1.select1.selectedIndex == 0){
...
} else if (document.form1.select1.selectedIndex == 1){
...
} else {
....
}
