You could also use innerText:
您还可以使用innerText：
function navratna()
{
var y=document.getElementById("navrat");
y.innerText="ahoj";
}
<body>
<table border="1">
<tr>
<td height="20" width="100" id="navrat">
</td>
</tr>
</table>
<input
type="button" value="pokus" onclick="navratna()"/>
</body>

valueis a property of form elements only. You have to use innerHTML:
value仅是表单元素的属性。你必须使用innerHTML：
function navratna()
{
var y = document.getElementById("navrat");
y.innerHTML = "ahoj";
}
There are also various other attributes to set only text (which would be the most appropriate in your situation), but they differ from browser to browser. innerHTMLis the best cross-browser way.
还有各种其他属性可以仅设置文本（最适合您的情况），但它们因浏览器而异。innerHTML是最好的跨浏览器方式。

Use innerHTMLinstead of value.
使用innerHTML代替value。
function navratna()
{
var y = document.getElementById("navrat");
y.innerHTML = "ahoj";
}
