此 HTML 代码用于选择旅行的日期和目的地。我想在自动完成功能之外显示我的结果（目的地）。
如何在框中调用自动完成结果（ jquery中的confirm检查语句）？if else
这是我的代码。
<!DOCTYPE html>

<title>Pick a Date</title>

// JavaScript Document
$(document).ready(function() {
$("#departing").datepicker();
$("#returning").datepicker();
$("button").click(function() {
var departing = $("#departing").val();
var returning = $("#returning").val();
var places = ["Canada","China","Chicago","Japan","Germany","London","Moskow","Paris","Phillipins","India","Russia","Srilanka"];
$("#tags").autocomplete({
source: places,
select: function(event, ui) {
$('#tags').text(ui.item.value);
}
});
if (departing === "" || returning === "") {
alert("Please select departing and returning dates.");
} else {
confirm("Would you like to go to " + ???? + " on " + departing + " and return on " + returning + "?");
}
});
});
