I have a dropdown list with several option, each option has a name attribute. When I select an option, a different list of checkboxes needs to appear - when another options is selected, that checkbox list should disappear and another one be displayed.
I have created these checkbox lists and given them an ID that correlates to the name attribute of the option selected. I am trying to use the following code to display the correct checkbox list
$(document).ready(function(){
$('#band_type_choices').on('change', function() {
$('.checkboxlist').hide();
$('#checkboxlist_' + $(this).attr("name") ).css("display", "block");
});
However nothing is happening.
Here is my dropdown options:
<select id="band_type_choices">
<option vlaue="0"></option>
<option value="100" name="acoustic">Acoustic</option>
<option value="0" name="jazz">Jazz/Easy Listening</option>
<option value="0" name="acoustic_jazz">Acoustic + Jazz/Easy Listening</option>
<option value="0" name="party">Party</option>
<option value="0" name="acoustic_party">Acoustic + Party</option>
<option value="0" name="jazz_party">Jazz/Easy Listening + Party</option>
<option value="0" name="acoustic_jazz_party">Acoustic + Jazz/Easy Listening + Party</option>
</select>
and an example of one of the lists:
<div class="checkboxlist" id="checkboxlist_acoustic" style="display:none;">
<input type="checkbox" class="checkbox keys" name="keys" value="100" />Keys<br>
<input type="checkbox" class="checkbox acou_guit" name="acou_guit" value="100" />Acoustic Guitar<br>
<input type="checkbox" class="checkbox drums" name="drums" value="100" />Drums<br>
<input type="checkbox" class="checkbox alt_sax" name="alt_sax" value="100" />Alto Sax<br>
<input type="checkbox" class="checkbox ten_sax" name="ten_sax" value="100" />Tenor Sax<br>
<input type="checkbox" class="checkbox clarinet" name="clarinet" value="100" />Clarinet<br>
<input type="checkbox" class="checkbox trombone" name="trombone" value="100" />Trombone<br>
<input type="checkbox" class="checkbox trumpet" name="trumpet" value="100" />Trumpet<br>
<input type="checkbox" class="checkbox flute" name="flute" value="100" />Flute<br>
<input type="checkbox" class="checkbox cello" name="cello" value="100" />Cello<br>
<input type="checkbox" class="checkbox violin" name="violin" value="100" />Violin<br>
</div>
$var = jQuery("#dropdownid option:selected"). val(); alert ($var); Or to get the text of the option, use text() : $var = jQuery("#dropdownid option:selected").
$('#mySelectBox option'). each(function() { if ($(this). isChecked()) alert('this option is selected'); else alert('this is not'); });
Syntax of jQuery Select Option$(“selector option: selected”); The jQuery select option is used to display selected content in the option tag. text syntax is below: var variableValue = $(“selector option: selected”).
For anyone who comes across this late, like me.
As others have stated, name isn't a valid attribute of an option element. Combining the accepted answer above with the answer from this other question, you get:
$(this).find('option:selected').text();
In your codethis
refers to the select element not to the selected option
to refer the selected option you can do this -
$(this).find('option:selected').attr("name");
The Code is very Simple, Lets Put This Code
var name = $("#band_type_choices option:selected").text();
Here You don't want to use $(this).find().text()
, directly you can put your id name and add
option:selected
along with text()
.
This will return the result option name. Better Try this...
$(this).attr("name")
means the name of the select tag not option name.
To get option name
$("#band_type_choices option:selected").attr('name');
Firstly name
isn't a valid attribute of an option
element. Instead you could use a data
parameter, like this:
<option value="foo" data-name="bar">Foo Bar</option>
The main issue you have is that the JS is looking at the name
attribute of the select
element, not the chosen option. Try this:
$('#band_type_choices').on('change', function() {
$('.checkboxlist').hide();
$('#checkboxlist_' + $('option:selected', this).data("name")).css("display", "block");
});
Note the option:selected
selector within the context of the select
which raised the change event.
