Radio Buttons

Pre-Set Radio Button Values

This is the JavaScript -
Yes No
The Code is
See source code for this script
Note -
- No html allowed inside alert window
- If each radio button is given same name rb, then an array rb[i] is automatically created with rb[0] denoting the first button.
- Each radio button may be given a separate name, such as rb1, rb2, etc. But array is more useful for loops.

Selected Radio Button Values

This is the JavaScript -
France England Germany Italy

The Code is

<script>
<!--
 function fu()
  {
   for( i=0; i< document.rform.rb.length; i++ )
      {
       if (document.rform.rb[i].checked) 
          {
           answer = document.rform.rb[i].value;
           alert(" You selected "+answer);
          }
      }
  }
// -->
</script>

<form name="rform">
 <input type="radio" value="yes" name="rb" checked> France
 <input type="radio" value="england" name="rb"> England
 <input type="radio" value="germany" name="rb"> Germany
 <input type="radio" value="italy" name="rb"> Italy
 <p>
 <input type="button" value="Get Selected Country" onClick="fu()">
</form>

Note -
- Leaving out if condition yields pop-up for all buttons.
- if condition must be inside for loop as it uses the i variable.
- Note how the "value" in the input tag is used instead of the label.
