使用jQuery在HTML中选择下拉列表中隐藏选项更改时的div

Question

To get straight to the point here's I want to accomplish. I want to hide a certain DIV when a certain <OPTION> in <SELECT> was selected.

Here's my HTML markup:

THE SELECT

<select name="cutoffselect" id="cutoff" class="text ui-widget-content ui-corner-all" style="padding-right: 80px;">
        <option value="">Choose One</option>
        <option value="daily">Daily</option>
        <option value="weekly">Weekly</option>
        <option value="semimonthly">Semi Monthly</option>
        <option value="monthly">Monthly</option>
  </select>

and the DIV I want to hide if DAILY was selected.

THE PERIOD

<div class="input-group-addon" style="width:20%;" title='Filter By' id = "perioddiv">   
    <!--PERIOD-->
       <label for="period" style="padding-right: 10px;margin-top:7px;" visible="false">Period</label>
          <select name="period" id="period" class="text ui-widget-content ui-corner-all">
                <option value="">Choose Period</option>
                <option value="">1</option>
                <option value="">2</option>
                <option value="">3</option>
                <option value="">4</option>
                <option value="">5</option>
          </select>
    <!--PERIOD-->
  </div>

I have tried using different query but I cannot do what I want. Here's the query I used but its not functioning and if I may ask for another jQuery suggestion that actually might work the greater. Thanks to all in advance.

HERE'S THE QUERY

  <script type="text/javascript">
     $("#cutoffselect").change(function(){
       $("#perioddiv div:eq(" + $(this).attr("selectedIndex") + ")").show();
    });
  </script>

Answer 1

this will do it:

<script type="text/javascript">
     $(function(){
         $("#cutoff").change(function(){
             if($(this).val()=='daily'){
                 $('#perioddiv').hide();
             }
             else{
                 $('#perioddiv').show();
             }
         });
     });
  </script>

To hide div with id=perioddiv when daily option selected, you can try below jquery:

<script type="text/javascript">
     // bind change event using '#cutoff' as select id="cutoff"
     $("#cutoff").change(function(){
       // hide if selected value is "daily"
       if($(this).val() == "daily")
          $("#perioddiv").hide();
       else
          $("#perioddiv").show();
    });
  </script>

Using the ID's you can easily sort this out by using:

$("#selectorID").hide();

    }

Check if the selected option is daily and then hide the div.

$(document).ready(function(){

    $('#cutoff').change(function(){

        if($('#cutoff option:selected').val() == 'daily')
        {
            $('#perioddiv').hide();
        }
        else
        {
            $('#perioddiv').show();
        }

     });

});

try this:

    if($(this).val() == "daily") {
        $('#perioddiv').hide();
    }

});
