Why my jQuery does not return to me the value of <select>
Question
My index.html :
<body>
<select id="car">
<option value="TOYOTA">TOYOTA</option>
<option value="BMW">BMW</option>
</select>
<input type=button id="get_btn" value="Get"></input>
<script src="myscript.js"></script>
</body>
myscript.js :
var btn=$('#get_btn');
btn.click(function(){
var car= $('#car').val;
alert(car);
});
When I press the get button, I expect an alert show the selected car, but I got an alert window with the jQuery val function code:
function (value) {
if (!arguments.length) {
var elem = this[0];
if (elem) {
....
Where goes wrong?

".val" is a function. Use:
var car= $('#car').val();

val is a function, not a variable. You need to amend your myscript.js code as follows:
var btn=$('#get_btn');
btn.click(function(){
var car = $('#car').val();
alert(car);
});

you have missing brackets :
var car= $('#car').val;
and should be :
var car= $('#car').val();
