我该如何处理这个AJAX（？）错误？

Question

所以我有一个错误，每次我尝试点击一个元素（由我使用jquery制作的自动完成功能生成）我只能在中间点击时访问它，但是，如果我使用箭头＆amp;每次都输入它。任何想法？我的代码是。也许我只是看不到它，但我看了几个小时

$(document).ready(function() {

    function autocomplete(inp) {
      var currentFocus;
      var arr =[];
      inp.on("input", function(e) {
          var a, b, i, val = this.value;
          closeAllLists();
          if (!val) { return false;}

          a = document.createElement("DIV");
          a.setAttribute("id", this.id + "autocomplete-list");

          this.parentNode.append(a);
