<select>我尝试默认隐藏，当我点击Edit按钮时我想显示它。但它没有按预期工作。
请在下面找到我的代码。
<!DOCTYPE html>
<html>
<head>
<script>
function update_country() {
if(document.getElementById("Editbtn").value == 'Edit'){
document.getElementById("country").style.display = 'none';
document.getElementById("Editbtn").value = "Update";
document.getElementById("countries").style.visible = 'true';
}
}
</script>
<style>
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 100%;
}
td, th {
border: 1px solid #dddddd;
text-align: left;
padding: 8px;
}
tr:nth-child(even) {
background-color: #dddddd;
}
</style>
</head>
<body>
<h2>HTML Table</h2>
<table>
<tr>
<th>Company</th>
<th>Contact</th>
<th>Country</th>
</tr>
<tr>
<td>Alfreds Futterkiste</td>
<td>Maria Anders</td>
<td id="country">Germany</td>
<td id="countryOption" visible =false>
<select name="countries" id="countries" >
<option value="Germany">Germany</option>
<option value="India">India</option>
<option value="France">France</option>
<option value="Italy">Italy</option>
</select>
<input id="Editbtn" type="button" value="Edit" onclick="update_country()">
</td>
</tr>
</table>
</body>
</html>
Am trying to modify `Country` column by click on the `edit` button. once i clicked on edit button existing `<td>` tag should be hidden and `select>` tag should be visible to select other country and update the column by clicking on the `udpate` button
