Tafiyar na karo na 4 - Tafiyar da JavaScript:

        /* Tafiqan kifina bai bai bai kuma gaba da zane-gaban da zane-gaban na kalmomi a kan halittu: */
        hanyan (arr[i].substr(0, val.length).toUpperCase() == val.toUpperCase()) {
          /* 为每个匹配元素创建一个 DIV 元素： */
          b = document.createElement("DIV");
          /* 将匹配的字母加粗： */
          b.innerHTML = "" + arr[i].substr(0, val.length) + "";

          /* 插入一个输入字段来保存当前数组项的值： */
          b.innerHTML += "";
          /* 当有人单击项目值（DIV 元素）时执行的函数： */
              b.addEventListener("click", function(e) {
              /* 插入自动完成文本字段的值： */
              inp.value = this.getElementsByTagName("input")[0].value;
              /*关闭自动完成值列表，或任何其他打开的自动完成值列表： */
              closeAllLists();
          });
          a.appendChild(b);
        }
      }
  });
  /* 当有人在键盘上按键时执行一个函数：*/
  inp.addEventListener("keydown", function(e) {
      var x = document.getElementById(this.id + "autocomplete-list");
      if (x) x = x.getElementsByTagName("div");
      if (e.keyCode == 40) {
        /*如果按下箭头向下键，增加 currentFocus 变量：*/
        currentFocus++;
        /* 并使当前项目更加明显：*/
        addActive(x);
      } else if (e.keyCode == 38) { //up
        /* 如果按下向上箭头键，减少 currentFocus 变量：*/
        currentFocus--;
        /* 并使当前项目更加明显：*/
        addActive(x);
      } sa if (e.keyCode == 13) {
        /* Idan yana a kama an yi kai shifan ENTER, za kai tinga sumbiti fangxian: */
        e.preventDefault();
        if (currentFocus > -1) {
          /* 并模拟点击“活动”项目：*/
          if (x) x[currentFocus].click();
        }
      }
  });
  function addActive(x) {
    /* 将项目分类为“活动”的函数：*/
    if (!x) return false;
    /* 首先删除所有项目中的 "active" 类：*/
    removeActive(x);
    if (currentFocus >= x.length) currentFocus = 0;
    if (currentFocus < 0) currentFocus = (x.length - 1);
    /* 添加 "autocomplete-active" 类：*/
    x[currentFocus].classList.add("autocomplete-active");
  }
  function removeActive(x) {
    /* 从所有自动完成项中删除 "active" 类的函数：*/
    for (var i = 0; i < x.length; i++) {
      x[i].classList.remove("autocomplete-active");
    }
  }
  function closeAllLists(elmnt) {
    /*关闭文档中的所有自动完成列表，除了作为参数传递的那个：*/
    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]);
    }
  }
}
/* 当有人单击文档时执行的函数*/
document.addEventListener("click", function (e) {
    closeAllLists(e.target);
});
}

第五步 - 在 "myInput" 上启用自动完成功能：

将国家数组作为 autocomplete 函数的第二个参数传递：

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