javascript - jQuery Get Selected Option From Dropdown

Usually I use $("#id").val() to return the value of the selected option, but this time it doesn't work.
The selected tag has the id aioConceptName

html code

Name



    choose io
    roma
    totti

Answer

For dropdown options you probably want something like this:

var conceptName = $('#aioConceptName').find(":selected").text();

The reason val() doesn't do the trick is because clicking an option doesn't change the value of the dropdown--it just adds the :selected property to the selected option which is a child of the dropdown.
