javascript - Counting the number of option tags in a select tag in jQuery

Question

How do I count the number of <option>s in a <select> DOM element using jQuery?

<select data-attr="dropdown" id="input1">
  <option value="Male" id="Male">Male</option>
  <option value="Female" id="Female">Female</option>
</select>

I want to find the number of <option> tags in the <select> DOM element, since with that I want to open the settings panel with that number of input fields with the corresponding option value from the drop-down box in it and to change it again in the preview panel.

The above drop-down box is in my preview panel which is generated by jQuery.

Answer 1

$('#input1 option').length;

This will produce 2.
