jQuery select change show/hide div event

Question

I am trying to create a form which when the select element 'parcel' is selected it will show a div but when it is not selected I would like to hide the div. Here is my markup at the moment:

This is my HTML so far..

    <div class="row">    
    Type
        <select name="type" id="type" style="margin-left:57px; width:153px;">
                <option ame="l_letter" value="l_letter">Large Letter</option>
                <option name="letter" value="letter">Letter</option>
                <option name="parcel" value="parcel">Parcel</option>
        </select>                    
</div>

<div class="row" id="row_dim">
    Dimensions
        <input type="text" name="length" style="margin-left:12px;" class="dimension" placeholder="Length">
        <input type="text" name="width" class="dimension" placeholder="Width">
        <input type="text" name="height" class="dimension" placeholder="Height">
</div> 

This is my jQuery so far..

  $(function() {
    $('#type').change(function(){
        $('#row_dim').hide(); 
        $("select[@name='parcel']:checked").val() == 'parcel').show();   
    });
});

Answer 1

Use following JQuery. Demo

$(function() {
    $('#row_dim').hide(); 
    $('#type').change(function(){
        if($('#type').val() == 'parcel') {
            $('#row_dim').show(); 
        } else {
            $('#row_dim').hide(); 
        } 
    });
});

<script>  
$(document).ready(function(){
    $('#colorselector').on('change', function() {
      if ( this.value == 'red')
      {
        $("#divid").show();
      }
      else
      {
        $("#divid").hide();
      }
    });
});
</script>

Do like this for every value Also change the values... as per your parameters

Answer 3

Try:

if($("option[value='parcel']").is(":checked"))
   $('#row_dim').show();

Or even:

$(function() {
    $('#type').change(function(){
        $('#row_dim')[ ($("option[value='parcel']").is(":checked"))? "show" : "hide" ]();  
    });
});

change your jquery method to

$(function () { /* DOM ready */
    $("#type").change(function () {
        alert('The option with value ' + $(this).val());
        //hide the element you want to hide here with
        //("id").attr("display","block"); // to show
        //("id").attr("display","none"); // to hide
    });
});
