Well, it looks like you want to iterate through all the radio buttons and disable/enable the appropriate field based on each "checked" value. Try this:
Code:<html> <head> <title>Disable Text Box</title> <script language="JavaScript"> function DisBox(fldobj) { var radios = fldobj.form.elements[fldobj.name]; for (var i=0; i < radios.length; i++) { var txtbox = radios[i].nextSibling; while (txtbox.nodeType == 3) { // make sure we get an element not a text node txtbox = txtbox.nextSibling; } txtbox.disabled = radios[i].checked ? "" : "true"; } } </script> </head> <body bgcolor="lightgreen"> <center> <form name="Distbox"> <input type="radio" name="disb" value="false" onclick="DisBox(this)"> <input type="text" name="txtb" size="30" disabled="true"> <input type="radio" name="disb" value="false" onclick="DisBox(this)"> <input type="text" name="txta" size="30" disabled="true"> </form> </center> </body> </html>
