Get drop down value

Question

How to determine what is selected in the drop down? In Javascript.

Answer 1

If your dropdown is something like this:

<select id="thedropdown">
  <option value="1">one</option>
  <option value="2">two</option>
</select>

Then you would use something like:

var a = document.getElementById("thedropdown");
alert(a.options[a.selectedIndex].value);

But a library like jQuery simplifies things:

alert($('#thedropdown').val());

Answer 2

Use the value property of the <select> element. For example:

var value = document.getElementById('your_select_id').value;
alert(value);
