Tatu - Ongeza CSS:

Kifaa kinahitaji kuwa na kina kina kina kina.

* { box-sizing: border-box; }
body {
  font: 16px Arial;
}
.autocomplete {
  /* Kifaa kinahitaji kuingia kwa kina kina kina kina: */
  position: relative;
  display: inline-block;
}
input {
  border: 1px solid transparent;
  background-color: #f1f1f1;
  padding: 10px;
  font-size: 16px;
}
input[type=text] {
  background-color: #f1f1f1;
  width: 100%;
}
input[type=submit] {
  background-color: DodgerBlue;
  color: #fff;
}
.autocomplete-items {
  position: absolute;
  border: 1px solid #d4d4d4;
  border-bottom: none;
  border-top: none;
  z-index: 99;
  /* Kufaa kusababisha kufikia kufikia kwa kina kina cha kifaa: */
  top: 100%;
  left: 0;
  right: 0;
}
.autocomplete-items div {
  padding: 10px;
  cursor: pointer;
  background-color: #fff;
  border-bottom: 1px solid #d4d4d4;
}
.autocomplete-items div:hover {
  /* Kama inasaidia kufikia vitu kwa kumtaarifu kwa kifungu: */
  background-color: #e9e9e9;
}
.autocomplete-active {
  /* Kama inasaidia kufikia vitu kwa kibatili cha kifungu: */
  background-color: DodgerBlue !important;
  color: #ffffff;
}

Taratibu ya nne - Ongeza JavaScript:

function autocomplete(inp, arr) {
  /* Mfano wa kuzingatia au kuzingatia kwa uraifu ni wa kuzingatia kwa kifaa cha jina na mifano yenye uwezo wa kuzingatia: */
  var currentFocus;
  /* Tukio ambao linategemea kufikia kwa sababu ya kuita kwenye kiini cha jina: */
  inp.addEventListener("input", function(e) {
      var a, b, i, val = this.value;
      /* Kufungua orodha ya thamani za kuzingatia ambazo zilizofunguliwa: */
      closeAllLists();
      if (!val) { return false;}
      currentFocus = -1;
      /* Kuunda kiini cha DIV kinachohusiana na mifano (maadili): */
      a = document.createElement("DIV");
      a.setAttribute("id", this.id + "autocomplete-list");
      a.setAttribute("class", "autocomplete-items");
      /* Kuongeza kama mtoto wa kiini cha kifaa cha kuzingatia jina: */
      this.parentNode.appendChild(a);
      /* Kufikia kila kipengele cha mazingira wa kifaa... */
      for (i = 0; i < arr.length; i++) {
        /* Tukioleza kama vitu vya kwanza vya kiini cha jina la kawaida linapatikana kwa ujumbe wa kawaida: */
        if (arr[i].substr(0, val.length).toUpperCase() == val.toUpperCase()) {
          /* Create a DIV element for each matching element: */
          b = document.createElement("DIV");
          /* Bold the matching letters: */
          b.innerHTML = "<strong>" + arr[i].substr(0, val.length) + "</strong>";
          b.innerHTML += arr[i].substr(val.length);
          /* Insert an input field to save the value of the current array item: */
          b.innerHTML += "<input type='hidden' value='" + arr[i] + "'>";
          /* Execute a function when someone clicks on the item value (DIV element): */
              b.addEventListener("click", function(e) {
              /* Insert the value of the auto-complete text field: */
              inp.value = this.getElementsByTagName("input")[0].value;
              /* Close the auto-complete value list, or any other open auto-complete value list: */
              closeAllLists();
          });
          a.appendChild(b);
        }
      }
  });
  /* Execute a function when someone presses a key on the keyboard: */
  inp.addEventListener("keydown", function(e) {
      var x = document.getElementById(this.id + "autocomplete-list");
      if (x) x = x.getElementsByTagName("div");
      if (e.keyCode == 40) {
        /* If the down arrow key is pressed, increase the currentFocus variable: */
        currentFocus++;
        /* And make the current item more prominent: */
        addActive(x);
      } else if (e.keyCode == 38) { //up
        /* If the up arrow key is pressed, decrease the currentFocus variable: */
        currentFocus--;
        /* And make the current item more prominent: */
        addActive(x);
      } else if (e.keyCode == 13) {
        /* If the ENTER key is pressed, prevent the form from being submitted: */
        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>
