在上面的一行中，我如何根据国家名称将单独的列表链接起来。如果我键入India，则此处是单独的列表，而不是列表项包含该URL，并且当用户点击它时，它会打开而不是填写输入字段。

您已经完成了大多数艰苦的工作，只需在单击列表后告诉javascript打开URL。 click事件已经存在，因此只需添加以下行：
window.open(this.children[0].href ,"_self");
这将从单击的列表项的第一个子项中找到href，然后在当前窗口中启动URL。
让我知道您是否还需要其他东西。

只需更改onclick函数即可更改窗口的位置
b.addEventListener("click", function(e) {
inp.value = this.getElementsByTagName("input")[0].value;
// get the value of href in tag a
href = this.getElementsByTagName('a')[0].href;
// open href in window
window.location.href = href;
closeAllLists();
});
