how to check how many options in a dropdown

Question

How do I check using jquery how many options are there in a drop down?

thanks.

Answer 1

alert($('#select_id option').length);

Answer 2

$('#idofdropdown option').length;

That should do it.

Answer 3

$("#mydropdown option").length

Or if you already got a reference to it,

$(myDropdown).find("option").length

Answer 4

var length = $('#mySelectList').children('option').length;

or

var length = $('#mySelectList > option').length;

This assumes your <select> list has an ID of mySelectList.

Answer 5

$('#dropdown_id').find('option').length

Answer 6

Use the length property or the size method to find out how many items are in a jQuery collection. Use the descendant selector to select all <option>'s within a <select>.

HTML:

<select id="myDropDown">
<option>1</option>
<option>2</option>
.
.
.
</select>

JQuery:

var numberOfOptions = $('select#myDropDown option').length

Answer 7

$('select option').length;

or

$("select option").size()

Answer 8

Get the number of options in a particular select element

$("#elementid option").length

Basically just target the ID of the select and do this:

var numberOfOptions = $('#selectId option').length;
