How do I check, using jQuery, how many options are there in a drop down menu?
Thanks.

You will use the following command to determine if there are any options within the select box. var length = $('#selectBoxId > option'). length; console. log(length);
If you press the " L " key on your keyboard once the drop-down menu is selected it would immediately scroll down to that option. This tip is helpful for large drop-down menus with several options (e.g., selecting a state or country).
To get the value of a select or dropdown in HTML using pure JavaScript, first we get the select tag, in this case by id, and then we get the selected value through the selectedIndex property. The value "en" will be printed on the console (Ctrl + Shift + J to open the console).
You can use the jQuery :selected selector in combination with the val() method to find the selected option value in a select box or dropdown list.
var length = $('#mySelectList').children('option').length;
or
var length = $('#mySelectList > option').length;
This assumes your <select> list has an ID of mySelectList.
