    Previous radion button checked

    I have 3 radio buttons - isPartOf, isNotPartOf, and delete

    I do some onscreen subtotaling when the buttons are clicked.

    This a list of contacts and each contact has these 3 radio buttons with a sub-total of the number of contact in the company.

    When the contacts are initially displayed all are part of the group. So the default "isPartOf" is checked.

    The status of each individual can then be changed.

    Clicking either "isNotPartO f" or "delete" will subtract 1 from the count.

    Then clicking "isPartOf" adds 1 back to the count.

    Here is the problem - If the user first clicks "isNotPartO f" that decrements 1 and then clicks "delete" for the same person that decrements again.

    I only want to subtract if the radio button that is being de-selected is "isPartOf"

    So is it possible to know which button was de-selected when "deleted" is selected.

      It would be easier to understand if you would post the code. Anyhow you can always store the data in Arrays and then compare the data to see what was deselected.

          In this case there is no code to post. Your point about the array is well taken, but may be more overhead than I am willing to put into the page.

          The question was simply can you detect which button is de-selected in a group of radio buttons when another is selected?

              Maybe this will help you:

              [code=html]
              <html>
              <head>
              <script language="JavaS cript">
              var Selected = '';
              function doSelect(Object )
              {
              alert('The deselected is: ' + Selected + ',\nThe selected is: ' + Object.value);
              Selected = Object.value;
              }
              </script>
              </head>
              <body>
              <input type="radio" name="list" onclick="doSele ct(this)" value="isPartOf ">isPartOf< br>
              <input type="radio" name="list" onclick="doSele ct(this)" value="isNotPar tOf">isNotPartO f<br>
              <input type="radio" name="list" onclick="doSele ct(this)" value="delete"> delete
              </body>
              </html>
              [/code]

                  That is very nice. Yes that is what I was looking for. Although on the first selection the alert did not give the deselect.

                  I even added the "checked" to the first button

                  Code:
                   <html>
     <head>
     <script language="JavaScript">
         var Selected = '';
         function doSelect(Object)
         {
             alert('The deselected is: ' + Selected + ',\nThe selected is: ' + Object.value);
             Selected = Object.value;
         }
     </script>
     </head>
     <body>
         <input type="radio" name="list" onclick="doSelect(this)" checked value="isPartOf">isPartOf<br>
         <input type="radio" name="list" onclick="doSelect(this)" value="isNotPartOf">isNotPartOf<br>
         <input type="radio" name="list" onclick="doSelect(this)" value="delete">delete
     </body>
 </html>
                  So thank you very much for the help.

                  I did solve the problem another way. I removed the "deleted" button when the "isNotPartO f" was selected.

                  And then if "isPartOf" was reselected, I restored the button

                  use this translation
                  exp_ = isPartOf
                  rem_ = isNotPartOf
                  del_ = delete

                  Code:
                  	if (cAction == 'rem_')
	{
		var elem = document.getElementById("del_"+cKey);
		elem.parentNode.removeChild(elem);
	}
	if (cAction == 'exp_' && !document.getElementById("del_"+cKey))
	{
		cVal  = document.getElementById("attr_"+cKey).innerHTML
		cVal += '<input ';
		cVal += 'type="radio" ';
		cVal += 'id="del_'+cKey+'" ' ;
		cVal += 'onclick="changeStatus(this);" ';
		cVal += 'value="RemoveFromCompany" ';
		cVal += 'name="'+cKey+'"/> ' ;
 
		document.getElementById("attr_"+cKey).innerHTML = cVal
	}

                      No problem ;)

                      BTW, adding checked won't fix the problem, you should have set the Selected variable to the default value in the <script>

                      [code=html]
                      <html>
                      <head>
                      <script language="JavaS cript">
                      var Selected = 'isPartOf';
                      function doSelect(Object )
                      {
                      alert('The deselected is: ' + Selected + ',\nThe selected is: ' + Object.value);
                      Selected = Object.value;
                      }
                      </script>
                      </head>
                      <body>
                      <input type="radio" name="list" onclick="doSele ct(this)" checked value="isPartOf ">isPartOf< br>
                      <input type="radio" name="list" onclick="doSele ct(this)" value="isNotPar tOf">isNotPartO f<br>
                      <input type="radio" name="list" onclick="doSele ct(this)" value="delete"> delete
                      </body>
                      </html>
                      [/code]
