targetting f.select rails form helper with javascript

I'm trying to retrieve the value of a f.select form helper in my rails application.

The code for the f.select is (in HAML):

= f.select :level, [["L1 - Super easy", 1], ["L2 - Warm-up", 2], ["L3 - Easy exam questions", 3], ["L4 - Moderate exam questions", 4], ["L5 - Difficult exam questions", 5]], id: "level-AS"

which results in the following html:

<select id="test_level" name="test[level]">

    <option value="1" selected="selected">L1 - Super easy</option>
    <option value="2">L2 - Warm-up</option>
    <option value="3">L3 - Easy exam questions</option>
    <option value="4">L4 - Moderate exam questions</option>
    <option value="5">L5 - Difficult exam questions</option>

</select>

The f.select has an id of "level-AS" and I have managed to target it using

$('#level-AS').select()

and that gives me Object { context: HTMLDocument → new, selector: "#level-AS" } but what I want is for it to return the actual value that has been selected, i.e. "Easy" or "Hard".

I also tried 

$('#level-AS').select().val()

and I have also tried

$('#level-AS').val()

but this returns undefined....

You should simply do:

$('#level-AS').val()

Or according to your html:

$('#test_level').val()

Sidenote, instead of targeting by id, you could do:

$('select[name="test[level]"]').val()

I think your problem is that the ID in your f.select is getting lost. I think it's due to how rails is splitting up the arguments into the various sections. Try this:

= f.select :level, [["L1 - Super easy", 1], ["L2 - Warm-up", 2], ["L3 - Easy exam questions", 3], ["L4 - Moderate exam questions", 4], ["L5 - Difficult exam questions", 5]], {}, {id: "level-AS"}

You can call val() method to get value.

$('#level-AS').val()
