jquery中带参数的调用函数

当我单击一个ID为button1的控件时,它调用一个名为getmakes的函数,我希望能够向它传递一个参数。在这种情况下,将接收数据的控件的ID。我做错什么了?

$(function () {

        $('#Button1').click(getMakes("'#output'"))
        $('#buttonClear').click(function () {
            $('#output').html('');
        });
});
function getMakes(myVar) {   
$.ajax({
    type: "POST",
    url: "WebService.asmx/dbAccess2",
    data: "{}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (msg) {
        var response = msg.d;
        $.each(response, function (index, value) {
            $(myVar).append(new Option(value, index));
        });
    },
    failure: function (msg) {
        alert('failure');
    }
});

}
