javascript - 如何使用把手用于带有 javascript 的自动完成搜索栏？

问题描述

目前我正在为幽灵 cms 制作一个自动完成搜索栏，我必须使用把手。我已经使用 html 完成了它，这是错误的，所以我可以做些什么来实现把手模板。这是html部分

<div class="autocomplete" style="width:300px;">
   <input id="myInput" type="text" name="myCountry" placeholder="Search">
</div>

Javascript部分是：-

<script>
function autocomplete(inp, arr) {
  var currentFocus;
  inp.addEventListener("input", function(e) {
      var a, b, i, val = this.value;
      closeAllLists();
      if (!val) { return false;}
      currentFocus = -1;
      a = document.createElement("DIV");
      a.setAttribute("id", this.id + "autocomplete-list");
      a.setAttribute("class", "autocomplete-items");
      this.parentNode.appendChild(a);
      for (i = 0; i < arr.length; i++) {
        if (arr[i].substr(0, val.length).toUpperCase() == val.toUpperCase()) {
          b = document.createElement("DIV");
          b.innerHTML = "<strong>" + arr[i].substr(0, val.length) + "</strong>";
          b.innerHTML += arr[i].substr(val.length);
          b.innerHTML += "<input type='hidden' value='" + arr[i] + "'>";
          b.addEventListener("click", function(e) {
              inp.value = this.getElementsByTagName("input")[0].value;
              closeAllLists();
          });
          a.appendChild(b);
        }
      }
  });
  inp.addEventListener("keydown", function(e) {
      var x = document.getElementById(this.id + "autocomplete-list");
      if (x) x = x.getElementsByTagName("div");
      if (e.keyCode == 40) {
        currentFocus++;
        addActive(x);
      } else if (e.keyCode == 38) { 
        currentFocus--;
        addActive(x);
      } else if (e.keyCode == 13) {
        e.preventDefault();
        if (currentFocus > -1) {
          if (x) x[currentFocus].click();
        }
      }
  });
  function addActive(x) {
    if (!x) return false;
    removeActive(x);
    if (currentFocus >= x.length) currentFocus = 0;
    if (currentFocus < 0) currentFocus = (x.length - 1);
    x[currentFocus].classList.add("autocomplete-active");
  }
  function removeActive(x) {
    for (var i = 0; i < x.length; i++) {
      x[i].classList.remove("autocomplete-active");
    }
  }
  function closeAllLists(elmnt) {
    var x = document.getElementsByClassName("autocomplete-items");
    for (var i = 0; i < x.length; i++) {
      if (elmnt != x[i] && elmnt != inp) {
        x[i].parentNode.removeChild(x[i]);
      }
    }
  }
 document.addEventListener("click", function (e) {
      closeAllLists(e.target);
  });
}

var countries = ["Afghanistan","Albania","Algeria","Andorra","Angola","Anguilla","Antigua","Argentina","Armenia","Aruba","Australia","Austria","Azerbaijan","Bahamas","Bahrain","Bangladesh","Barbados","Belarus","Belgium","Belize","Benin","Bermuda","Bhutan","];

autocomplete(document.getElementById("myInput"), countries);
</script>

所以，我的问题是我在 .hbs 文件中执行此操作，我不知道如何将把手用于搜索功能。如果我尝试创建一个

{{#each}} 
  {{somedata}}
{{/each}}

我应该如何将我的车把部分与我的 javascript 部分链接起来是行不通的。我有人用 jquery 做这件事，但它只是让我头疼。所以任何人都可以帮忙。PS：-如果您无法理解，我也会分享更多详细信息。
