Javascript not working when jquery is added

问题:

I am new to javascript n jquery. I used javascript along with jquery on my script tag.When jquery is not added, the javascript works fine,but when a jquery function is added, the script is not working.....shall i convert both to javascript or both to jquery or am i missing anything.Here is my script

<script type="text/javascript">
function getLocations() {
    $.post('@Url.Action("getLocations","Home")', { 'id': $("#cities").val() },
        function (data) {
            $("#loca").html(data).show();

        });
}

$(function () {
$('.submit').on('click', function () {
    var ck = "";
    var city = $("#cities option:selected").text();
    var location = $("#loca option:selected").text();
    alert(city+"and"+location)
}
});

</script>

you forgot a )

$(function () {

    $('.submit').on('click', function () {
       ...
    })   // <---
});

if you properly indent the code blocks and if you look on the javascript console, this kind of errors become easier to be detected. Just adopt an indent style and write code adhering to it.
