removing the display:none according to your code you are using bootstrap after removing it if it not working check the jquery and javascript links pattern like

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

answer2: 回答2:

you have style display:none on it change it to block

or you could opt for a (small bit of js) option and go for this

Here is a fiddle

var mytextbox = document.getElementById('country');
var mydropdown = document.getElementById('dropdown');

mydropdown.onchange = function(){
    mytextbox.value= " ";
     mytextbox.value = mytextbox.value  + this.value;
}
textarea, select{display:block; vertical-align:top;  height:27px;}
<select id="dropdown">
<option value="aichach">Aichach</option>
<option value="allende">Allende</option>
<option value="atlanta">Atlanta</option>
<option value="bangalore">bangalore</option>
<option value="berlin">Berlin</option>
<option value="bristol">bristol</option>
<option value="calgary">Calgary</option>
<option value="california">California</option>
<option value="campuchia">Campuchia</option>
<option value="carapicuiba-sao-paulo">Carapicuíba - São Paulo</option>
<option value="conakry">Conakry</option>
<option value="dallas">Dallas</option>

Ref

你有风格显示:没有它改变它阻止

或者你可以选择一个(点点JS)选择走这

这里有一把小提琴

var mytextbox = document.getElementById('country');
var mydropdown = document.getElementById('dropdown');

mydropdown.onchange = function(){
    mytextbox.value= " ";
     mytextbox.value = mytextbox.value  + this.value;
}
textarea, select{display:block; vertical-align:top;  height:27px;}
