如果找不到结果，jQuery自动完成

Question

我已经完成了jQuery自动完成脚本的工作。该脚本运行正常。但是，当响应为“未找到结果”时，不应激活location.href。在这种情况下，location.href就在那里。

jQuery：

$(document).ready(function($) {
  $("#customers").autocomplete({
    source: "/core/country/fetch_customers.php?cc=<?php echo $agencyid; ?>",
    minLength: 2,
    select: function(event, ui) {
      var code = ui.item.id;
      if (code != '#') {
        location.href = '/view-customer/' + code;
      }
    },
    response: function(event, ui) {
      if (!ui.content.length) {
        var noResult = {
          value: "",
          label: "No results found"
        };
        ui.content.push(noResult);
      }
    },
    // optional (if other layers overlap autocomplete list)
    open: function(event, ui) {
      $(".ui-autocomplete").css("z-index", 1000);
    }
  });
});
