javascript - Show div if radio value selected -

-

i show div if radio value selected hide again if different value selected

<input type="radio" name="timespan" id="timespan" value="ongoing" checked>on-going <input type="radio" name="timespan" id="timespan" value="history">historical   <script type="text/javascript">         $(document).ready(function() {           $('.end_date').css('display','none');               $('#timespan').click(function () {                var selected = $(this).find(':checked').val();                     if(selected == 'history') {                    $('.end_date').css('display','block');                 } else {                    $('.end_date').css('display','none');                  }           });                }); </script>

if history selected want elements class end_date show, otherwise if ongoing selected them hidden

html markup should not include 2 elements same id, id on page should unique, instead add class timespan both radio buttons.

in code .hide() , .show() can used in place of setting display property block or none.

also instead of finding checked radio button, can assume clicked button checked. simplifies code $(this).val(); instead of $(this).find(':checked').val();

html

<input type="radio" class="timespan" name="timespan" value="ongoing" checked>on-going <input type="radio" class="timespan" name="timespan" value="history">historical <div class="end_date">end date</div>

javascript

    $(document).ready(function() {       $('.end_date').hide();           $('.timespan').click(function () {            var selected = $(this).val();                 if(selected == 'history') {                $('.end_date').show();             } else {                $('.end_date').hide();              }       });            });
